Testo completoAbstract (sommario):
The possibility to replace a part of soybean meal in sow, piglet and growing finishing pig feed by high and low alkaloid varieties of two species of lupines was examined in this study. 50 Polish Landrace sows and their progeny were allocated to 5 groups. Two varieties of Lupinus angustifolius: low (Graf) in group II and high alkaloid (Karo) in group III and Lupinus luteus: low- (Mister) in group IV and high alkaloid (Parys) in group V, partly replaced soybean meal (control). Apparent digestibility was evaluated using the same feeds on 30 barrows: around 40 kg (grower) and 80 kg (finisher). Litter weight of piglets from lupine groups was significantly lower than that from control group. Between 35th and 84 day piglet fed with low-alkaloid lupine (Graf) gained better than others and than soybean meal. Feed enzyme supplement has only limited effect on piglet and growing pig performance. During the whole fattening period there was no significant difference in weight gains except group fed high-alkaloid cv. Karo which was the worst. Meat of pigs fed with lupines was poorer in PUFA n-3 than control. Results suggest low alkaloid varieties of blue and yellow lupine, given in moderate amount, give similar results in growing pig feeding than soybean meal but meat quality is lower.

Testo completoAbstract (sommario):
The expediency of fusarium resistant lupines usage in organic farming for improving soil fertility and producing high protein feed for livestock is justified in this article.
Organic production excludes the use of mineral fertilizers and pesticides. In these circumstances, increases the value of cultures that positively affect the fertility of soils and their phytosanitary status. These crops include annual fodder lupine (yellow, white and angustifolia), especially varieties that are resistant to disease.
Having the highest nitrogen-fixing ability among annual legume crops, lupins, depending on the type and conditions of cultivation, can accumulate from 80 to 300 kg/ha of environmentally pure symbiotic nitrogen in biomass. Plowing the green mass (30-45 t/ha) is equivalent to the corresponding amount of manure or introduction of 5-7 t/ha of ammonium nitrate. 30 kg/ha of phosphorus and 50 kg/ha of potassium are entering the soil with plant remains. Therefore, lupine provides itself with nutrients and still leaves up to 150 kg/ha of nitrogen in the soil after harvesting for subsequent crops in crop rotation.
In organic production, fusariosis resistant varieties of lupines are also interesting as a source of high protein feeds for livestock. They are building up to 60 t/ha of biomass, which contains more than one ton of digestible protein. In grain of the fodder varieties contains 40-52% of crude protein, 5.5-6.0% of fat, 10-12% of sugar.
The characteristic of fusarium resistant varieties of lupins (yellow, white and angustifolia), created in the NSC "Institute of Agriculture NAAS" and included in the Register of Plant Varieties of Ukraine is presented in this article. These varieties are practically not affected by fusariosis under the production conditions and do not require the use of fungicides during the growing season. They can be grown in crop rotation with a return period of 2-3 years, whereas for unstable it took 6-7 years. Because of the inability to use in organic farming fungicide to prevent crop losses from anthracnose, it is necessary to use predominantly angustifolia lupine varieties, which are now more tolerant to this disease, prevent sowing of infected seeds and adhere to crop rotation.
Fusarium-resistant varieties of lupins are suitable for cultivation in poucous and sown crops, and in mixtures with other crops.

Abstract The aim of the study was to determine the usefulness of two protein concentrates composed of rapeseed meal and new cultivars of narrow-leaved and yellow lupine, peas in laying hen diets and their influence on birds’ performance and egg characteristics. The experiment was conducted with 180 layers kept in individual cages. The birds were randomly assigned to three treatments, with 60 hens in each and during the period of 17 weeks, they were fed diets: I - containing soybean meal as a protein source, II - containing protein concentrates composed of mixture of lupines, peas (19.48% of diet) and rapeseed meal, III - containing protein concentrates composed of a mixture of lupines and peas (27.68% of diet). The body weight, laying rate, egg weight, feed intake and feed conversion ratio (FCR) and egg characteristics were registered. After 9 weeks of experiment, a decrease of laying rate was recorded in treatment III. The mean value of laying rate for 17 weeks amounted to 82.7 (I), 82.5 (II) and 75.9% (III) (P<0.01). The egg weight was diversified already after 4 weeks of egg production and averaged 57.9 (I), 55.9 (II) and 54.9 g (III) (P<0.05). Feed intake amounted to 108 (I), 111 (II) and 104 g per hen/day (III), and FCR was 2.05, 3.17 and 2.23 kg/kg egg weight, respectively. As to egg characteristics, increases of white index (P<0.05), Haugh unit score and yolk colour in treatment III were observed but egg shell thickness was found significantly reduced. In conclusion, the use of about 27.68% of legume seed in laying hen diet affected negatively performance results but about 19.48% of these seeds and 8% rapeseed meal in diets could be accepted as a soybean meal substitute.

Lupins (Lupinus; Leguminosae) as a high protein, high energy, nitrogen-fixing grain legume, have the potential to be used as a home-grown feedstuff to replace soya (Glycine max) in livestock feeds in the UK. Lupins are not typically grown in the UK but their high feed value and the low alkaloid concentrations in new varieties have prompted a renewed interest in their use (Wilkins and Jones, 2000). Traditionally, white lupin (Lupinus albus) is the predominant species fed as a soya replacement to dairy cows in Europe and the USA but recent research has shown advantages of growing yellow lupins (Lupinus luteus) in the UK compared with white lupins. This study reports on the effects of feeding concentrate diets containing yellow lupin compared with soya bean meal on intakes, milk productivity and milk composition in dairy cows.

Testo completoAbstract (sommario):
In the experiment, the effect of additive on the fermentation quality of lupine was examined, by comparing with the untreated control. Fresh green Lupine (Lupines lupine), variete Juno, dry matter content 187.15 g/kg at full waxy stage of maturiy were chopped to the legth of cut ca 30–50 mm. The crop was artificially wilted for a periody 24 h and ensiled as described above. Lupine were ensiled for 98 days in laboratory silos, capacity about 4 L alone or with supplementation of feed additive (5, 10, 20, 30, 40, 50 or 70 kg/tone forage respectively). The composition and as effective substances of this silage ingredient were dry whey (30%), maize meal (40%) and dry molases (30%). The silages fermented rapidly and changes in volatile fatty acids (VFA) production (P<0.01) and in sum of acids were noted. The different supplementation of additive in our experiment conditions increased significantly (P<0.01) the dry matter content, and decreased statistically significantly (P<0.01) the pH value. The higher DM content was in all experimental silages, but the highest DM content (P<0.01) was in silage with addition of 70 kg/t (231.58Ī0.91 g/kg). All treated silages were well fermented with low levels of ammonia and pH. The different addition of this aditive increased significantly (P<0.01) the contents of lactic acid and total content of acids in comparison with control silage. The experimental silage with higher (5%, resp. 7%) feed supplementation was of better quality (significantly higher ratio LA/sum of acids, higher content of lactic acid, lower NH3 content and pH value) than the control silage, or silage with lower concentration. In experiment feed additive–treated silages (by groups of 5 or 50 and 70 kg/t) had significantly higher alcohol content than untreated silage. It was concluded that feed additive used as a silage additive improved fermentation of lupine, reduced acetic acid and ammonia production and increased silage nutritive value.

Testo completoAbstract (sommario):
Lupins (Lupinus spp.) are an ancient yet important legume crop. In Europe, the protein-rich seeds serve as livestock feed and have the potential to be a healthy vegetarian component of human diets. In some regions in north-eastern Europe, lupins are heavily damaged by two Curculionidae species, the lupin root weevils (LRWs) Charagmus gressorius (syn. Sitona gressorius) and Ch. griseus (syn. S. griseus). Narrow-leaved lupins (L. angustifolius) and white lupins (L. albus) are most affected. The weevils feed on lupin leaves, whereas their larvae feed on root nodules. Therefore, the larvae cause major root damage by creating lacerations that allow soil-borne plant pathogens to enter the plant tissue. These infestations lead to considerable yield losses and markedly reduced N-fixation of the root nodules. This review summarises the current knowledge on the origin, geographical distribution, and biology of these rarely described weevils. It focuses on management strategies, including preconceived insecticide use and potential ecological management methods, as key components of an integrated pest management programme against LRWs in Europe.

Testo completoAbstract (sommario):
The rough-seeded lupins are better adapted to alkaline soils than the domesticated lupins currently in use in commercial agriculture in southern Australia. Lupinus pilosus and L. atlanticus are two species of rough-seeded lupins that are undergoing domestication, and could be very valuable for sheep as a supplementary feed. However, there is little information on the nutritive value of these lupins. Two experiments were conducted to evaluate the nutritive value of L. pilosus and L. atlanticus, compared with L. angustifolius, which is widely used as an animal feed in Australia. The results showed that the rough-seeded lupins examined had larger seeds, a greater proportion of seed coat in the whole seed, and a higher fibre content in the seed coat than domesticated lupins. Nitrogen (N) content in the kernel of the various lupin species was similar. The high fibre content in seed coat did not appear to limit the digestion of the seeds by sheep as demonstrated by the high potential degradability of seed dry matter (DM) for all lupin species. There were no significant differences betweenL. pilosus,L. atlanticus, andL. angustifolius as a supplementary feed provided at low levels in DM digestibility (DMD), apparent energy digestibility (AED), and N-balance, suggesting that L. pilosus and L. atlanticus could be used in place of L. angustifolius. AlsoL. atlanticus could be substituted for L. angustifolius at high levels of supplementation as there were no differences in DMD, AED, apparent N digestibility, and N-balance when these species were fed to sheep as a supplement to barley straw. Supplementation with lupin seed at 150 g/day significantly improved DM intake by 195 g/day, DMD by 8.7, and AED by 11.4 percentage units. However, a high level of lupin supplementation in a diet based on barley straw did not increase DMD and AED of the diet.

Soya bean (Glycine max) meal is an important component of animal feed and oil seed rape and palm kernel cake and meal are typically used in commercial concentrate diets for sheep in the UK.. Lupins (Lupinus; Leguminosae) as a high protein, high energy, nitrogen-fixing grain legume, have potential as a home-grown livestock feed in the UK (Wilkins and Jones, 2000). Research has been conducted on the effects of narrow-leafed lupins (Lupinus angustifolius) (Hill, 2005) but there have been few studies on the effects of yellow lupins (Lupinus luteus) when fed to sheep. This study investigated the effects of incorporating either yellow lupins, narrow-leaf lupins or soya bean meal into the concentrate diets of finishing lambs on lamb productivity and carcass characteristics when compared to a commercial UK lamb finisher diet.

The seeds of sweet lupine cultivars (Lupineus species) have been used with increasing frequency as a source of proteins replacing proteins of animal origin or soybean in feed compounds. The seeds of sweet lupine cultivars contain an average of about 33-40% crude protein in dry matter, the lipid content ranges from 5 to 13%. The profile of amino acids is relatively beneficial, however, with slightly lower content of lysine (1.46%) and methionine (0.22%). The main storage carbohydrates in the seeds are the β-galactans that comprise most of the cell-wall material of the kernel and the cellulose and hemicellulose of the thick seed coats. Lupine seeds contain about 40% non-starch polysaccharides (NSP) and a negligible amount of starch. High coefficient of protein digestibility (> 90%) has been reported in sweet lupine cultivars, but lower digestibility of energy (~ 60%). Lupineus species contain negligible amounts of trypsin inhibitor so they do not require preheating before being used as an ingredient in feeds for monogastric animals. The efficiency of lupine seeds in the diets for pigs is characterized by controversial results of growth and feed conversion under both mechanical treatment and enzyme supplementation. The results of production efficiency obtained at the testing of lupine cultivars (L. albus, L. angustifolius) for pigs were beneficial at supplementation of the lacking nutrients or dehulling. The submitted paper summarizes national as well as foreign knowledge of the nutritive value of cultural lupine seeds, and deals with the possibility increasing nutrition and production efficiency in the diets for pigs.

Testo completoAbstract (sommario):
Organic Soybean cultivation experiences an upscale at the moment in Switzerland. As in the rest of Europe, Switzerland is still heavily dependent on protein imports. After years of stakeholders efforts of the development of a value chain for organic soybeans for human nutrition, various attempts to develop the soybean cultivation for feed proved to be fruitful despite the fact that Swiss price level is beyond competition for world market prices. The organic farmers themselves decided to become, at least partially, more independent from overseas soybean imports by opting for organic soybeans of European origin since 2019. Furthermore, Bio Suisse decided that from 2022 on, all ruminants under Bio Suisse certification must be fed with feed of Swiss origin, concentrates are limited to 5% of the ration. Since many years numerous projects are carried out to increase the domestic protein production by developing suitable production systems for peas, faba beans, lupines and soybeans with stakholders along the value chain. Since more than 30 years, Swiss breeders successfully develop 00 to 000 soybean varieties with a focus on human nutrition, organic soybean cultivation and the respective value chains from breeding to endproduct is developing strongly. This article will shed light on particular aspects and drivers, specific measures, relevant projects and cultivation techniques of organic soybean production in Switzerland in the past years and will give an outlook on the future of organic soybeans.

Testo completoAbstract (sommario):
Several lupin (Lupinus) species are native to southern Spain (2). The white lupin, Lupinus albus L., is the most important crop, and its seeds are used for human consumption and animal feed. Accessions of three indigenous species, L. albus, L. angustifolius L., and L. luteus L., and an introduced species from South America, L. mutabilis Sweet, were planted during October in replicated yield trials in acidic soils (pH 6.5) in the Sierra Morena Mountains (elevation 350 m) north of Córdoba. Root and crown rot disease was widespread and very serious on the indigenous lupins, particularly in several patches of white lupin cultivars. Infected plants were devoid of feeder rootlets, and the tap roots, crowns, and lower stems were necrotic and turned dark brown to black. Rotted roots were colonized heavily by fungal oospores. Many affected plants wilted and died before flowering. A Phytophthora sp. was isolated consistently from the necrotic roots and crowns of symptomatic white lupins. The same fungus also was isolated from the necrotic root tissues of the other indigenous lupin species. Isolates of the fungus from diseased white lupins were homothallic and produced oospores rapidly and abundantly on corn meal and V8 agars. Antheridia were amphigynous, and aplerotic oospores ranged from 22 to 32 μm (average 27 μm). Nonpapillate, ovoidobpyriform sporangia were produced only in water on simple sympodial sporangiophores. Cultures on V8 agar grew at 5 to 30°C (optimum ≈25°C). The species was identified as Phytophthora erythroseptica Pethybr. based on morphology of oospores, sporangia, and other cultural characteristics (1). Koch's postulates were fulfilled by planting seeds of white lupin cv. Multulupa in sterile potting soil infested with a blended culture on V8 agar from a white lupin isolate of P. erythroseptica and reisolating the fungus after 28 days from lesions that developed on the roots and crowns of inoculated plants incubated in a greenhouse at 16 to 26°C. The fungus was not isolated from white lupins seeded in potting soil inoculated with sterile V8 agar. In pathogenicity tests, two isolates of P. erythroseptica from white lupins caused severe symptoms on the roots and crowns of inoculated white lupin cv. Multulupa similar to those observed on white lupins naturally infected in field trials. These isolates also caused root and crown rots on inoculated L. luteus and L. angustifolius. The fungus did not infect the roots or crowns of tarwi (L. mutabilis cv. SCG 20), alfalfa (Medicago sativa cv. Moapa), bean (Phaseolus vulgaris cv. Contender), chickpea (Cicer arietinum cv. Blanco Lechoso), faba bean (Vicia faba cv. Arboleda), lentil (Lens culinaris cv. local), pea (Pisum sativum cv. Lancet), soybean (Glycine max cv. Akashi), or subterranean clover (Trifolium subterraneum cv. Seaton-park). The tests were repeated, and the results were similar. This is the first report of P. erythroseptica infecting Lupinus spp. References: (1) D. C. Erwin and O. K. Ribeiro. 1996. Phytophthora Diseases Worldwide.

Testo completoAbstract (sommario):
Australia is the world’s leading source of lupin grain, producing ~1 million tonnes annually, of which 30% is used by the domestic livestock industry and the rest is exported for use in animal diets, including dairy cows. The domestic dairy industry uses ~70 000 tonnes annually, mainly as a supplementary feed source in pasture-based systems. Although much published information exists on the nutritive value of lupins for dairy cows, it tends to be fragmented and, in some important instances, exists only in the form of reports or publications outside the mainstream scientific journals. This paper aims to present a critical assessment of the current knowledge regarding the nutritional value of lupins as a feed for dairy cows, and offers recommendations for future research. For cows grazing pasture or fed diets based on conserved pasture or cereal hay, the mean fractional response to lupin feeding was 0.53 kg milk/kg DM lupins, with a range of 0–0.97 kg/kg. The mean fractional forage substitution rate was 0.54 kg DM/kg lupins, and this appeared to be independent of the type of basal forage. In experiments using cows fed iso-nitrogenous and iso-energetic total mixed rations, substituting oilseed protein such as soybean meal with cracked lupin grain had no significant effects on yield of milk, fat, and protein, but it reduced milk protein concentration and had mixed effects on fat concentration. There were no significant differences in milk yield or in fat or protein concentration when lupins were substituted for other pulse grains such as faba beans or peas. Treatment of lupin grain with heat or formaldehyde reduced lupin protein degradability in the rumen, but was not shown to have consistent benefits over untreated lupins in terms of increased milk yield. Substitution of cereal grains with an equivalent weight of lupins in dairy concentrate rations generally resulted in increased yield of milk, fat, and protein, and a higher fat concentration. The higher yield responses in most cases could be explained on the basis of the higher metabolisable energy content of lupins compared with cereal grains, although the contribution from a potentially lower incidence of rumen lactic acidosis could not be discounted. Feeding Lupinus albus lupins to cows significantly increased the concentration of C18 : 1 in milk and reduced that of C12 : 0–C16 : 0, thus shifting the fatty acid profile of milk towards national dietary guidelines for improved cardiovascular health in human populations. Although the review lists some recommendations for improving the nutritive value of lupins, current commercially available cultivars possess characteristics that make them attractive as a feedstuff for dairy cows.

SUMMARYThough bitter white lupin (Lupinus albus L.) is a traditional crop in Ethiopia, sweet lupins are new to the country. As a result, the nutritional value of low-alkaloid lupins has not been evaluated under Ethiopian conditions. Crude protein, amino acid and alkaloid contents of 16 cultivars of three annual lupin species grown in four lupin growing locations (Merawi, Finoteselam, Kossober-1 and Kossober-2) of Ethiopia were evaluated. Location × cultivar interaction was a significant source of variation for all traits (p < 0.0001). In all locations, blue entries had either similar (p ≥ 0.0584) or higher (p ≤ 0.0235) forage crude protein content than the Local Landrace, white group and yellow entry. Compared with the Local Landrace, white and blue entries, the sole yellow entry had higher (p ≤ 0.0148) seed crude protein content at all locations except at Kossober-2, where it had similar (p = 0.8460) crude protein content as white entries. The Local Landrace had the highest forage and seed alkaloid contents. However, sweet blue Vitabor and Sanabor entries had the lowest forage and seed alkaloid contents, respectively. Low alkaloid and higher crude protein contents of sweet lupins grown in Ethiopia show the possibility to use sweet lupin forage and seeds as cheap home-grown protein source for livestock feed and human food in the country. However, for more reliable information, the laboratory results need to be verified by animal and human evaluations of the crop.

"Peas-oats-vetch" is a traditional annual forage crop in Newfoundland, cut as needed in late fall, and fed as fresh feed. We tested the potential of increasing yield biomass and N concentration of the annual forage mixture through the substitution of white lupin (Lupinus albus L.) for pea (Pisum sativum L.) in 1990 and 1991. On mineral soils, lupin and pea were seeded at rates of 10, 20, 40, and 80 seeds m−2 in 132 seeds m−2 oat (Avena sativa L.) mixtures, and compared with pure-stand oat. Oat-lupin and oat-pea mixtures, planted at similar seeding rates, were also harvested at weekly intervals between 8 and 14 wk after planting. Oat-lupin, oat-pea and pure-stand oat were evaluated in an additional experiment on peat soils. On mineral soils, oat-lupin mixtures yielded forage with similar, or greater, dry matter yields and N concentration than pure-stand oats and oat-pea mixtures. Greatest yields were attained when mixtures were planted with 20 to 40 lupin seeds m−2, and harvested 10 to 12 wk after early summer planting. On peat soils, white lupins were susceptible to diseases that did not affect peas, resulting in oat-lupin yields that did not differ from pure-stand oats. White lupin can be considered an alternative legume in oat-legume mixtures grown on mineral soils in eastern Newfoundland. Key words: Lupinus albus L., Pisum sativum L., oat-legume forage, podzolic soil, peat soil

Testo completoAbstract (sommario):
Summary. The seeds of lablab (Lablab purpureus) and lupin (Lupinus angustifolius) were investigated as supplements for young sheep. In experiment 1, rumen-cannulated sheep were offered low quality roughage ad libitum alone or supplemented with about 5, 10 or 20 g/kg liveweight whole lupin or lablab seed. Rumen ammonia concentrations were increased by each level of both supplements, and the increases were greater with lupins than with lablab. The pH of rumen fluid was decreased by both supplements, particularly when the higher levels were fed. Dry matter of broken seeds of both legume species rapidly disappeared from synthetic fibre bags incubated in the rumen. Roughage dry matter disappearance from synthetic fibre bags decreased (P<0.05) when 20 g/kg liveweight lupins was fed, and this level of both supplements reduced (P<0.05) roughage intake. Total dry matter intake was increased more by lablab than by lupins, but dry matter and organic matter digestibility tended to be increased to a lesser extent by lablab. Overall, digestible organic matter intake and liveweight gain were increased to similar extents by both supplements. Wool growth was lower (P<0.05) with lablab than lupins, particularly at the highest level of supplementation, suggesting that availability of some amino acids was lower with lablab supplement. In experiment 2, rumen-cannulated sheep were fed low quality roughage ad libitum and supplemented with about 10 g/kg liveweight of either lupin or lablab seed. Lectins and protease inhibitors present in the lablab seed disappeared rapidly from synthetic fibre bags incubated in the rumen. In conclusion the nutritional value of lablab seed as a supplement for sheep fed low quality roughage was similar to that of lupin seed for liveweight gain, but was lower for wool growth.

Testo completoAbstract (sommario):
The demand for ovine milk and ovine dairy products is constantly increasing due to their exceptional sensorial characteristics and their health benefits for consumers. However, dairy fat content and composition are of particular concern for consumers as well as the medical community, as there are risk factors for coronary disease, diabetes mellitus, cancer, and other serious diseases. For this reason, attempts have been made to control/regulate the fat composition of ovine milk by modifying sheep dietary intake of polyunsaturated fatty acids. In this experimental trial, a group of sheep were fed for 30 days a diet enriched in flaxseeds and lupines, feed ingredients rich in omega-3 fatty acids, aiming to investigate the effects on fat composition and the microbiota of ovine milk. Chemical analysis of the collected milk showed that the omega-3 and omega-6 content was increased. On the opposite, the atherogenic and thrombogenic indexes decreased. Of importance was the semi-protective effect on the udder by the increased omega-3 dietary intake, as depicted by its impact on the biodiversity of the pathogenic microbiota. These findings suggest that ovine milk could be modified under specific conditions to be more appropriate for the consumption by people belonging to high-risk groups for various diseases.

Abstract The possibility of replacing soybean meal with a mixture of legume seeds and rapeseed press cake (RPC) was evaluated on 60 pigs weighing about 30 kg at the beginning of the experiment. Pigs were allocated to 5 experimental groups. Group I (control) received standard feed mixture containing soybean meal as a main protein source. Next groups received rapeseed press cake (RPC) mixed with fodder pea (Pisum sativum var. Ramrod) - group II, field bean (Vicia faba var. Kasztelan) - group III, blue lupin (Lupinus angustifolius var. Regent) - group IV or yellow lupin (Lupinus luteus var. Mister) - group V. Soybean protein was replaced by experimental protein sources at about 30% in grower (17% legumes, 13% rapeseed press cake) and at 100% in finisher diets (experimental proteins in equal ratio accounted for about 55% of mixture protein). Limited feeding was used, water was available ad libitum. Half the animals in each group received mixtures supplemented with fibrolytic enzymes Ronozyme VP and Ronozyme WX. Apparent digestibility of feed nutrients was estimated using the balance method on 30 fatteners not used in the fattening experiment, weighing about 40 kg for grower and 70 kg for finisher diets. Gross composition of legume seeds and RPC, amino acid composition of their protein, glucosinolate content in RPC and tannin content in faba bean and alkaloids in lupins were analysed. Carcass traits and meat quality were also estimated. Legume protein content ranged from 19.6% (pea) to 39.8% (yellow lupin). RPC protein contained more sulphur amino acids than legume protein. There was no significant difference in protein and fat digestibility. Body weight gains of fatteners fed with blue lupin were comparable to controls but significantly lower than those of the remaining groups. Supplemental enzymes improved body weight gains of fatteners receiving field bean. There was no significant difference in carcass traits and meat quality except for sensory analysis. It is concluded that the mixture of RPC and legume seeds can replace soybean meal in fattener feed.

Testo completoAbstract (sommario):
Over recent years, the demand for livestock products in Ethiopia is increasing; most of this demand is coming from urban centers, especially from Addis Ababa, as the buyers are demanding better quality and more hygienic produce. This has fueled interest in better quality animal feed, mainly from larger-scale commercial livestock producers. With this background, there has been interest in stimulating plant-based protein production that can be incorporated into livestock feed. Small quantities of lupins are grown (less than 20,000 ton per year) in the North Western part of Ethiopia for human consumption. These lupins are bitter due to their alkaloid concentration and are unsuitable for livestock feed. If non-bitter (sweet) varieties are grown, then they could be a source of protein for animals as is the case in some countries, such as Australia. The Ethiopian market for livestock feed was surveyed and segmented to evaluate the opportunities for lupins. The survey revealed that the livestock sector in Ethiopia is suffering from feed shortage both in terms of quality and quantity. Lupin, as a potential protein source feed has an opportunity to be incorporated into the livestock feed industry. Currently it is estimated that if sweet lupins were available, the short-term demand from commercial livestock producers and feed processors market segment is 20,000 t/year. In the medium-term, it is expected that as the national poultry production expands, there will be an increased demand from the large feed mill factories to around 35,000 to 40,000 t/year grain for high quality protein such as lupin. It is recommended that the already started sweet lupin promotion in the country has to be done at scale. In addition, production of sweet lupin in Ethiopia should be focused on the commercial farming sector and the marketing should be through the large-scale processors or direct to large-scale livestock producers.

Testo completoAbstract (sommario):
An experiment was conducted to determine the appropriate dietary concentration of albus lupins that would lower feed intake and decrease backfat while optimizing the effect on the growth rate of immunocastrated male pigs. The pigs were fed albus lupins (varying from 0 to 200 g/kg) from 2 weeks after the last immunization against GnRF for 14 d prior to slaughter (where d 0 is the day of the last immunization against GnRF). Increasing the dietary albus lupin concentration decreased daily gain for d 15 to 28 (p = 0.004). Daily feed intake also decreased as the concentration of the albus lupins increased for d 15 to 28 (p < 0.001). Carcass weight and backfat decreased as the concentration of dietary albus lupins increased (p = 0.011 and p = 0.024, respectively). The albus lupin concentration to maximize growth rate, minimize feed intake, maximize carcass weight and minimize backfat depth was 120, 142, 62.7 and 138 g/kg, respectively.

Testo completoAbstract (sommario):
In order to fi ll the existing protein defi ciency in the rations of farm animals in particular dairy cows it is necessary to input feed lupins as widely as possible in crop rotations. Lupin is a very versatile forage crop it can be used in feed as herbage, in the form of haylage, silage, in compound feed as a protein additive, as well as a green manure crop to increase soil fertility. Questions of protein nutrition should be to be quickly resolved, both in the production of protein and in its standardized rational use. Unbalanced protein rations increase feed consumption per unit of production, thereby increasing its prime cost. In the world soya is generally recognized as a protein feed, but in the Kaliningrad region as in most of regions in our country, it does not maturate being a heat-loving crop. Under these environments the inclusion of extruded lupine grain in the composition of energy-protein concentrates for the production of compound feed has become an alternative to replacing expensive soya. The researches have been carried out it the cattle farm of LLC “Temp” in the Guryevsky area in the Kaliningrad region (March-May 2019) on feeding lactating cows energy-protein concentrate from extruded grain of narrow-leaved lupine, fl ax, triticale, subjected to heat treatment on a press extruder. For this purpose two groups of lactating cows of Black-and-White breed (control and experimental) have been formed using the method of pairs of analogs per 11 heads in each. Cows of the control group have received the main ration of the farm, and cows of the experimental group in addition to the main ration have received compound feed with extruded energy-protein concentrate based on lupine. As a result of research, the positive infl uence of energy-protein concentrate based on lupine in compound feed on the dairy productivity of cows has been established. Recipes of concentrate and compound feed with concentrate for lactating cows, the volume of inclusion of components in the concentrate and in the compound feed have been calculated. During the experiment, the milk yield in the experimental group of cows has increased by 62,4 kg or 8,0 %, than in the control group. From the cows of the experimental group the conditional profi t has been received in the amount of 1684,8 rubles per head.

Testo completoAbstract (sommario):
Poll Dorset x (Border Leicester x Merino) lambs were weaned at 6 weeks and fed ad libitum diets of whole wheat, oat or barley grain with 0, 15, 30, 45,60 or 75% lupin grain, or all lupin grain, for 11 weeks. All diets included 10% hay. The lambs adapted to diets containing barley and wheat more quickly than to diets containing oats. Digestibilities of grain DM with hay alone were: wheat 83%, oats 73%, barley 75%, and lupins 83%. Inclusion of lupins in wheat-based diets had no effect on digestibility or intake of feed or weight gain of lambs. Inclusion of lupins with oats increased digestibility ( P < 0.05) and intake of feed (P< 0.05) and caused a slight rise in feed intake:liveweight gain ratio, but greatly reduced feed intake:carcass gain ratio (P< 0.05). Inclusion of lupins with barley increased digestibility and intake of feed (P< 0.05), and caused a slight fall in the feed intake:liveweight gain ratio (P<0.05) and a large fall in the feed intake:carcass gain ratio (P<0.05). Responses to lupins were generally most pronounced as lupin content increased from 0 to 30%. Liveweight, carcass weight, wool growth, abdominal fat and muscle depth at rib 12 were all linearly related to intake of digestible DM (P<0.05). Dressing percentage increased up to a maximum as daily intake of digestible DM increased to 0.55 kg/sheep and then fell (P<0.05). Liveweight was greater, but dressing percentage less, for lambs fed oats than for those fed barley or wheat (P<0.05). Carcass weights of lambs fed different grains were therefore similar at the same intakes of digestible DM.

Abstract The article presents the material on the most up-to-date, the global problem of protein deficiency in complete feedback for fish. One of the ways to solve this problem may be the use of white lupine (Lupinus Albus) in the structures of feed recipes. An important condition for the successful development of fish farming and the implementation of planned products for the production of products, to ensure food safety, occupy feeding issues. The decision of this issue puts a number of tasks to ensure feedback, rational methods of production, on the basis of advanced scientific achievements that contribute to the technological, economic development of the industry. Therefore, in experienced formulations of complete feed, the main task was to replace the white most expensive protein component into Lupine, that is, fish flour. In the first experienced recipe, the amount of lupine natives was 10%, which made it possible to reduce the fisherous flour content by 7%. The second experimental recipe in its structure contained lupine white without a shell in an amount of 22%, this made it possible to reduce the content of fish flour by 14%. The third experienced rechart contained Lupine without a shell of 25%, which made it possible to reduce the content of fish flour by 19%. Consequently, the use of white lupine in the formulations of complete feed, makes it possible to improve their nutritional value. And the use of lupine without a shell makes it possible to replace high-fingered animal feed in greater volume.

Testo completoAbstract (sommario):
Two experiments were conducted to examine the nutritive value of yellow lupins for weaner pigs. Using a completely randomised block design, Experiment 1 was conducted to determine the optimum inclusion level for yellow lupins (cv. Wodjil) in the diet of weaner pigs (6.14 kg ± 0.278). Experiment 2 was conducted using a 2 × 2 factorial design to examine whether supplementation of an enzyme preparation (VegPro) either in a soybean meal-based diet (0 g/kg yellow lupins) or in a yellow lupin-based diet (150 g/kg) improved performance of piglets (6.17 kg ± 0.317). In Experiment 1, the feed conversion ratio significantly increased at week 1 (linear effect, P = 0.040) and at week 3 (quadratic effect, P = 0.010) as the concentration of yellow lupins increased in the diet. In Experiment 2, supplementation with the enzyme preparation improved the feed conversion ratio in the pigs fed the lupin-based diet only but not in the pigs fed the soybean meal-based diet in week 2 (interaction P = 0.001). The results indicate that the optimum inclusion levels of yellow lupins for piglets immediately after weaning was 150 g/kg, and supplementation of a multi-enzyme preparation to a yellow lupin-based diet for the weaner pigs improved performance relative to the soybean meal-based diet.

The article is devoted to the current world problem of vegetable protein deficiency, the solution of which can be white lupine. Particular attention is paid to assessing the bioavailability of nutrients from white lupine (Lupinus albus) in the body of non-human primates M. Mulatta. Because primates are phylogenetically closer to humans than other laboratory animals, which is very convenient for modeling and studying the digestibility of nutrients in diets. The purpose of the article is to study the digestibility of nutrients in lupine in the structure of complete feed and its effect on the biochemical parameters of the blood. As a result of the research, it was found that the inclusion of white lupine in the structure of the diet allows to improve the bioavailability of nutrients of complete feed, when included in the structure of the diet of white lupine in an amount of 10%, it made it possible to improve the digestibility of crude protein in relation to the control group by 5.5%, crude fat by 0.99%, crude fiber by 1.84%, BEV by 7.99%, crude ash by 4.67%, calcium (Ca) and phosphorus (P) by 6.99%, and 1.02 %. With the inclusion of 20% white lupine in the structure of the diet, it made it possible to improve the digestibility of crude protein in relation to the control group by 9.28%, crude fat by 6.5%, crude fiber by 5.98%, BEV by 2, 78%, crude ash by 11.28%, and absorption of calcium (Ca) and phosphorus (P) by 9.93% and 8.68%. At the same time, the results of hematological analyzes generally indicate the safety of consuming white lupine for 35 days.

Testo completoAbstract (sommario):
The response of 9-month-old Angus steers, grazing sandplain lupins during summer and autumn and fed oat and oat plus urea supplements, or grazing hay made from the lupins and fed no supplement, was studied in two experiments. In the first experiment there were 3.3 t DM/ha present at the start of grazing. Average daily weight changes over 84 days were -0.548, -0.274 and 0.333 kg/day (P<0.05) for steers fed 0, 1 and 2 kg oats/steer.day respectively. The steers grazing lupin hay averaged -0.417 kg/day. There were 8.4 t DM/ha present at the start of the second experiment and the daily weight changes by steers fed 0, 2 and 6 kg oats plus urea/head.day were - 0.012, 0.524 and 0.952 kg/day (P<0.05), respectively. The steers grazing lupin hay gained 0.215 kg/day. No obvious clinical signs of lupinosis were observed in either experiment. However, in the first experiment the lupins were toxic, liver damage occurred and lupinosis may have contributed to the lower growth rates. In both experiments steers not fed a supplement made compensatory weight gains during winter and spring, when all steers were run together on mixed clover-grass pasture.

Testo completoAbstract (sommario):
Lupins are high in crude protein, cell wall materials, and gross energy but uncertainty about the bioavailability of nutrients and adverse effects on feed intake limit their use in the pig industry. Three experiments were conducted to determine the effect of lupins on retention time in the digestive tract by determining the average time it took for ingested polyethylene beads to pass through the digestive tract of pigs fed wheat-based diets containing various lupin species and fractions. In Expt 1, pigs were restrictively fed (1.8 kg/day) diets containing either predominantly wheat or predominantly wheat plus 400 g/kg peas or L. angustifolius seeds or kernels. The retention times of diets containing 400 g/kg of L. angustifolius seeds or kernels were significantly greater than those containing wheat alone (66.4 and 64.3 v. 48.8 h, P < 0.05, s.e.d. = 7.7 h), while that for the diet containing 400 g/kg peas was intermediate (55.8 h). In Expt 2 and 3, pigs were fed 1 of 6 wheat-based diets balanced for digestible energy (DE) and amino acid composition and containing either animal protein or 350 g/kg of peas, and L. angustifolius seeds or kernels, or L. albus seeds and kernels. Pigs were restrictively fed (1.5 kg/day) for Expt 2 or fed ad libitum for Expt 3. The mean retention time of the L. albus diets was greater than the other diets in both experiments. Feed intake and daily gain were reduced in pigs fed diets containing L. albus. Despite having lower feed intakes, pigs fed diets containing L. albus had more digesta in the stomach and small intestine at slaughter than the pigs consuming the diets not containing lupins. Appropriate physical treatment or enzymatic supplementation of L. albus diets may alleviate some of the feed intake problems.

The aim of this study was to determine and evaluate the chemical composition of the seeds of the genus Lupinus and soybeans. The chemical analyses were carried out in frequently grown lupin varieties in Europe (AMIGA, ANDA, ATU, BORUTA, BUTAN, DIETA, JUNO, KARO, PRIMA, ROSE, SONET and WATT) and two locally grown varieties of soybeans (KORADA and VISION). The contents of individual substances in analysed lupin seeds showed large differences in chemical composition of individual lupin varieties (crude protein: 317.06 - 458.86 g kg-1; lipids: 52.15 - 125.76 g kg-1; fibre: 101.21 - 154.23 g kg-1; non-nitrogenous extractive substances: 285.94 - 436.47 g kg-1; starch: 41.31 - 102.65 g kg-1; organic matter: 951.75 - 966.24 g kg-1; ash: 33.76 - 48.25 g kg-1; calcium: 2.29 - 5.10 g kg-1; phosphorus: 4.62 - 8.04 g kg-1; magnesium: 1.36 - 2.51 g kg-1; acid detergent fibre: 133.13 - 209.25 g kg-1). Lupin seeds were characterized by high contents of crude protein; in some varieties they significantly exceeded the content of crude protein in soybeans. In contrast to lupine seeds, soybeans contained a significantly higher content of lipids and lower content of fibre including acid detergent fibre. In lupin seeds, a negative correlation coefficient was found between the crude protein and BNLV content (r = -0.93) and between crude protein and starch content (r = -0.79). A positive correlation (r = 0.76) was found between the starch and BNLV content in lupin seeds. The results of the study provide information not only for growers regarding the choice of individual lupin varieties, but also for breeders who intend to use lupin seeds as suitable components for feed rations and mixtures.

Recent work on the agronomy and the genetic make-up of a new strain of lupin, which could be grown on almost half the agricultural land in England and Wales, has resulted in improvements in the yield and protein content of lupins. The protein content of lupins, at 37 % of the dry matter, is higher than that of either peas or beans and therefore lupins could be an important source of home-grown protein. There is little information available on the potential of new strains of lupins as a protein source in the feed of ruminants, particularly in conjunction with forage maize.

Testo completoAbstract (sommario):
A completely randomised design study with a 3 × 2 factorial arrangement was conducted. A total of 480 male broiler chickens were used to determine the influence of phytase addition, plant protein source [soybean meal, soybean meal + 200 g/kg of blue lupin meal (Lupinus angustifolius L.) or soybean meal + 200 g/kg yellow lupin meal (Lupinus luteus L.)] on performance of broiler chickens, ileal calcium (Ca), phosphorus (P) and protein digestibility, tibia bone characteristics and nitrogen-corrected apparent metabolisable energy. All diets were deficient in Ca, available P as well as lysine and total sulfur amino acids. Birds fed different protein sources were characterised by similar bodyweight gain and feed intake during the whole trial but feed conversion ratio was higher when birds were fed supplemented with yellow lupin meal (P < 0.05). Phytase improved bodyweight gain and feed conversion ratio regardless of protein source (P < 0.05). Diets supplemented with 200 g/kg blue or yellow lupin meal were found to be lower in nitrogen-corrected apparent metabolisable energy than soybean meal diets (P < 0.05). Birds fed diets supplemented with phytase were characterised by higher utilisation of Ca and P than birds whose feed was not supplemented with phytase (P < 0.05). Tibia bone ash as well as Ca content was similar across protein sources (P > 0.05), whereas tibia P content was lower when soybean meal or blue lupin meal was used (P < 0.05). Birds fed diets supplemented with blue lupin meal were characterised by the highest tibia P content (P < 0.05). Birds fed phytase-supplemented diets were characterised by higher tibia Ca and P content irrespective of protein source.

Testo completoAbstract (sommario):
Lupin grain typically provides the main source of protein in most lamb finisher diets in Western Australia. The aim of this work was to determine whether alternative sources of nitrogen could provide a less expensive means of achieving the desired rate of liveweight gain and carcass characteristics. Fifty-one crossbred lambs were finished using 3 different sources of crude protein. These sources were either: (i) a control diet consisting of lupins, oats, barley and cereal chaff in which lupins provided 49% of the nitrogen (lupin diet); (ii) a diet consisting of a combination of cereal grain and urea (urea diet); or (iii) a diet in which lupins were partially replaced with expeller canola meal (canola diet). Diets were isonitrogenous (14.4% crude protein) and isoenergetic (10.5 MJ ME/kg DM). Lambs were gradually introduced to the diets over 2 weeks before being fed the diets ad�libitum for 5 weeks.Lambs fed the canola diet performed the best in terms of feed intake and liveweight gain while those fed the urea diet performed the worst. Respective growth rates for sheep fed the canola, lupin and urea diets were 272, 233 and 180 g/day, respectively, with significant (P<0.05) differences only between the canola and urea diets. Equivalent dry matter intakes for the 3 groups were 1660, 1570 and 1380 g/day respectively, with sheep fed the urea diets being significantly (P<0.05) lower than the other two. Acidosis was considered to be a major cause of the poor performance of sheep fed the urea diet, with 3 sheep from this treatment showing inappetance and markedly reduced growth rates ('shy feeders'). Lambs finished on all 3 diets produced acceptable carcasses. Carcass weights followed the trend of growth rates, but there were no significant differences between diets in carcass weight, dressing percentage, GR tissue depth, C�site fat depth, eye muscle area, muscle pH or meat colour. At the price of the feeds used in this trial, the canola meal diet was the cheapest feed per kilogram of liveweight gain despite being the most costly diet per tonne of feed.

Lupinus albus seeds from low-alkaloid varieties are a valuable alternative source of protein for reducing the dependence on soybean meal for the feeding of monogastric animals. Therefore, the aim of this research was to evaluate the dehulling influence of lupine seeds (L. albus, cv. Amiga) and the effect of their use in the laying quails feed on live performance and egg quality. A total of 200 laying quails (Coturnix japonica), with an age of 10 weeks, were randomly assigned to five experimental groups (five replicates/group). Each group was randomly assigned to one of five dietary treatments: the control group (C) diet was based on soybean meal, while the experimental groups received either 200 g/kg (WLS20) or 250 g/kg (WLS25) of whole lupine seeds in their diets, or 200 g/kg (DLS20) or 250 g/kg (DLS25) of dehulled lupine seeds in their diets. The results show that by dehulling the lupine seeds, the nutritional value of the seeds increased. The use of dehulled lupine seeds in the diet of laying quails did not affect the live performance (egg production, feed intake, feed conversion ratio), yolk cholesterol content, and physico-chemical quality indices of the eggs, compared with control. The presence of dehulled lupine seeds in the diet improved the nutritional quality of the yolk lipids because of the increase in the content of polyunsaturated fatty acids. Thus, the lipid quality indices of the yolk became more favorable to consumer health because of an increase in the h/H ratio (hypocholesterolemic/Hypercholesterolemic FA) and a decrease in the atherogenic index and thrombogenic index values. The higher content in carotenoids also contributed to the higher nutritional quality of the eggs obtained by lupine utilization. In conclusion, dehulling of lupine seeds had a positive influence on the nutritional quality of the seeds, the live performance of quails, and the quality of eggs.

Testo completoAbstract (sommario):
The objective of this study was to determine the effect of alkaloids present in blue lupine (Lupinus angustifolius) seeds on the growth rate, selected indicators of carbohydrate and lipid metabolism, and liver morphology in rats. The experimental material comprised 32 Wistar rats at around 3 weeks of age, with an initial body weight of 81 g. During a 28-day feeding trial, the rats were fed diets containing the seeds of three blue lupine cultivars, Baron, Zeus and Wersal, with different alkaloid concentrations (0.36, 0.41, 0.56 mg/kg, respectively). Diets containing the seeds of three blue lupine cultivars reduced the feed intake and significantly limited the growth rate of experimental rats, compared to the control group. Lupine alkaloids had no effect on the serum concentrations of glucose and total cholesterol in rats, whereas elevated triglyceride concentrations were noted in experimental groups, relative to the control group. Diets containing the seeds of blue lupine cultivars Zeus and Wersal induced changes in alanine transaminase activity. A histopathological analysis of the liver revealed parenchymatous degeneration, which was more advanced in rats fed diets with the seeds of blue lupine cultivars Zeus and Wersal than in the control group, and congestion of portal vessels, which was more severe in rats fed the seeds of blue lupine cultivars Baron and Zeus.

Testo completoAbstract (sommario):
Two hundred and twenty-four crossbred male pigs (Large White × Landrace, initial bodyweight 27.2 kg ± 0.22) were used to determine the influence of dietary Australian sweet lupin (ASL) inclusion level and enzyme supplementation on growth performance, carcass composition and meat quality. The experiment was a 4 × 2 factorial design with the respective factors being ASL inclusion level (Lupinus angustifolius L., cv. Mandelup; 200, 250, 300 and 350 g/kg, in replacement of soybean meal) and enzyme supplementation (without or with supplemental enzyme; Allzyme SSF). Pigs (7 pigs per pen × 4 replicates per treatment = 28 pigs per enzyme by lupin-level combination) were fed grower diets between 27 and 50 kg, finisher diets between 50 and 75 kg and pre-sale diets between 75 and 107 kg, and daily gain and feed intake were measured weekly. At ~107 kg liveweight, the pigs were slaughtered at a commercial abattoir and carcass composition was measured. Meat quality (pH, surface exudate, drip loss, cooking loss, meat colour and shear force) was measured from selected pigs (n = 18) fed the lowest and highest lupin diets without enzyme supplementation. Increasing the ASL inclusion level to 350 g/kg did not alter (P > 0.05) growth performance of pigs and did not influence (P > 0.05) carcass composition and meat quality. Likewise, addition of supplemental enzyme had no effect (P > 0.05) on growth performance and carcass composition. Lack of performance response to added enzyme complex is likely due either to the use of enzyme complex that was not substrate-specific for the lupin non-starch polysaccharides or to the high specification of the experimental diets, which was inevitable when increasing inclusion levels of lupins. The results show that a current variety (Mandelup) of ASL can be used in grower/finisher diets up to 350 g/kg without compromising growth, carcass composition or meat quality of pigs.

Testo completoAbstract (sommario):
During a three-stage fattening period, 30 weaners, gilts and young boars of a three-breed cross – ♀ (Landrace x Yorkshire ) x ♂ Duroc – were fattened from body weight 27.2 to 117.5 kg. The animals were divided into three groups of 10, a control (K) and two experimental groups (D1 and D2). The pigs were fed total mixed rations and their daily weight gain and feed conversion were monitored. Soybean extraction meal was the only source of protein in the mixtures for the control pigs. In the mixtures for the experimental animals, the soybean extraction meal was partially replaced with seeds of yellow lupine. The proportion of the seeds was constant, irrespective of the stage of fattening, at 7.5% (D1) or to 15% (D2). After fattening and slaughter, basic carcass parameters were determined: hot carcass weight (kg), backfat thickness between the 3rd and 4th rib (mm), thickness of m. longissimus dorsi (MLD) and meatiness (%). Economic calculations, i.e. the differences between revenue (sale of the fatteners) and costs, were performed as well. The introduction of 7.5% and 15% yellow lupine in the mixtures for the experimental fatteners did not negatively affect the results of fattening. Daily weight gains in groups K, D1 and D2 were very good, amounting to 1,056 g, 1,075 g and 1,081 g, respectively (P>0.05). Feed consumption per kg of BW gain was also good: K – 2.72, D1 – 2.72, and D2 – 2.69 kg/kg. The carcass parameters in the groups were similar (statistically insignificant differences). A simplified analysis of production efficiency showed a positive rate of change, i.e. D1 vs. K – 18.53% and D2 vs. K – 8.56%, which confirms the benefits of using yellow lupine seeds in pig fattening.

Testo completoAbstract (sommario):
Narrow-leaved lupine (Lupinus angustifolius L.) is a cultivated multipurpose species with a very short history of domestication. It is used as a green manure, and for feed and food. This crop shows good prospects for use in pharmacology and as a source of fish feeds in aquaculture. However, its genetic potential for the development of productive and adaptable cultivars is far from being realized. For crop species, the genetic base of the cultivated gene pool has repeatedly been shown as being much narrower than that of the wild gene pool. Therefore, efficient utilization of a species’ genetic resources is important for the crop’s further improvement. Analyzing the information on the germplasm collections preserved in national gene banks can help perceive the worldwide diversity of L. angustifolius genetic resources and understand how they are studied and used. In this context, the data on the narrow-leaved lupine collection held by VIR are presented: its size and composition, the breeding status of accessions, methods of studying and disclosing intraspecific differentiation, the classifications used, and the comparison of this information with available data on other collections. It appeared that VIR’s collection of narrow-leaved lupine, ranking as the world’s second largest, differed significantly from others by the prevalence of advanced cultivars and breeding material in it, while wild accessions prevailed in most collections. The importance of the wild gene pool for the narrow-leaved lupine breeding in Australia, the world leader in lupine production, is highlighted. The need to get an insight into the species’ ecogeographic diversity in order to develop cultivars adaptable to certain cultivation conditions is shown. The data on the testing of VIR’s collection for main crop characters valuable for breeders are presented. Special attention is paid to the study of accessions with limited branching as a promising gene pool for cultivation in relatively northern regions of Russia. They demonstrate lower but more stable productivity, and suitability for cultivation in planting patterns, which has a number of agronomic advantages. Analyzing the work with narrow-leaved lupine genetic resources in different national gene banks over the world helps shape the prospects of further activities with VIR’s collection as the only source of promising material for domestic breeding.

Full-fledged feeding of animals is the basis for the manifestation of their genetic potential of productivity and transformation of feed nutrients into products. This is possible only with the introduction of feeds into the diets that ensure their fullness with energy, protein, minerals, vitamins in the necessary quantities and ratios. In this regard, the narrow-leaved lupin is of great interest. In terms of protein content and amino acid composition, it is almost equivalent to soy. In addition, unlike soy, lupin grain does not contain trypsin inhibitors, which allows it to be used for ruminants without pretreatment and in sufficient quantities. As a result of exploratory research, compound feeds-concentrates containing extruded grain of lupine, fodder beans (50%), flax, paisa, as well as crushed cereals were developed and tested. New recipes of compound feeds with a high content of the energy-protein complex of crops grown in the Kaliningrad region ensure high productivity of animals. In the cows of the experimental groups for 60 days of the accounting period of cows, the average daily milk yield of natural milk was higher by 2.05 and 3.27 kg. Milk of basic (3.4%) fat content was obtained by 165 kg and 265 kg, milk fat by 5.63 kg and 9.04 kg and milk protein by 4.55 kg and 6.97 kg. At the same time, their cost is significantly less than soy, sunflower and rapeseed meal purchased outside the region. Taking into account the cost of feed, additionally received from the sold products, in comparison with the control, for the I experimental group 13483 rubles and II experimental 21255 rubles, from every 15 cows.

Testo completoAbstract (sommario):
The narbon bean (Vicia narbonensis) is a grain legume which shows agronomic potential in southern Australia. In the present study narbon beans (50 and 100 g kg-1) were compared with lupins (Lupinus augustifolius) and field peas (Pisum sativum) (100 g kg-1), in starter diets for broiler chickens. There were two control diets one which contained soybean meal (1 10 g kg-1) and a second which contained meat and bone meal (65 g kg-1) as the major protein supplement. The diets were fed from 1 to 2 1 days, each to 48 male chickens. There were no significant effects (P< 0.05) of dietary inclusion of narbon beans at either 50 or 100 g kg-1on feed intake, liveweight, liveweight gain or feed conversion ratio of broiler chickens when compared with the other protein sources.

Testo completoAbstract (sommario):
The article is devoted to the current problem of providing rations with a source of protein with a high biological value. Such a source is suggested to be white lupine and products of its processing. Since, white lupine exceeds the protein content of peas, vetch and other legumes by more than 10%. And the significant content of fat in its composition allows, when using it, to reduce or completely abandon the use of sunflower oil in the diet. This favorably distinguishes white lupine from soybean and sunflower meal and cake, as well as partially animal feed, which are currently used as the main sources of fodder protein. This statement is confirmed in our experiments. As a result, it was found that the use of white lupine in the structures of complete feeds can improve the nutritional value of rations. It has a positive effect on the increase in live weight in animals with the inclusion of native white lupine in the structure of the diet in an amount of 10% to 33%, respectively, with a content of lupine in the diet of 20%, the increase in live weight is 95% higher. Provides a decrease in the cost of the resulting complete feed, when lupine is included in its structure in an amount of 10% by 4.35% and with a lupine content of 20%, the cost of 1 kg of compound feed is reduced by 14.49%. The use of white lupine allowed the experimental animals to use the food efficiently. The lowest costs were observed in the 3 test group. Energy costs were lower by 48.80%, crude protein by 47.22% and digestible protein by 51.3%. In the 2 experimental groups, the costs of metabolic energy, crude protein and digestible protein were lower by 25.00%, 26.38% and 39.20, respectively. Thus, the inclusion of white lupine in the structure of the diet helps to improve the nutritional value of rations, to reduce the cost of nutrients and feed, improving the economic indicators of the maintenance of animals.

Testo completoAbstract (sommario):
Sweet white lupin (Lupinus albus) is an emerging crop in Ontario and, in 1993, up to 600 ha acres of lupin were planted. This crop is adapted to cool and moderately warm climates, is frost-resistant to −2 °C, requires sandy to loamy soils, requires inoculation with Bradyrhizobium sp. to achieve high yields, and improves soil structure and nutrients when included in a crop rotation. The crop requires 119–135 d to mature and is thermosensitive; both traits can reduce yield in seasons with unfavourable environments. The crop is not particularly competitive with weeds and effective weed control is a critical factor in crop production. Lupin is attacked by several pathogens and insects but knowledge on appropriate pest management practices needs to be improved. The harvested seed of sweet white lupin is primarily used as an on-farm source of protein. Seeds do not require heat treatment prior to being used as animal feed and can be included as a part of the protein component in the diets of ruminants, swine and poultry. High protein digestibility and high fibre content of lupin seeds can limit incorporation into the diets of ruminants and swine, respectively. Lupin can be beneficial in human diets because milk from lupin-fed animals contains more unsaturated fatty acids and less saturated fatty acids than milk from animals fed soybean meal. Sweet white lupin has several advantages and disadvantages as an emerging crop in Ontario, but additional research and development are needed. Key words: Lupin (sweet white), Lupinus albus

Abstract The limiting factor of yield is often the insufficient supply of plants with nutrients during the growing season. In this regard, it is necessary to find new techniques that provide a solution to this problem. The article presents the results of studies of micro-fertilizers on the yield and quality of white lupine grain. The use of Aquamix ST fertilizers and potassium Metaborate contributed to an increase in the yield of white lupine grain by an average of 37.5 and 35.4%. In all variants of applying Aquamix ST, an increase in the protein content in the white lupine grain of the Pilgrim variety was found. The excess over the control varied from 5.0 to 5.8 %. The use of Aquamix ST and potassium Metaborate on vegetative plants reduced the alkaloid content of lupin grain by 24.7 … 34.6%. Treatment of white lupine crops in the budding phase with Aquamix ST and potassium Metaborate increased the carotene content in the grain by 34.3 - 25.0%, respectively. The analysis of the data showed that the maximum amount of lysine and carotene was characterized by a variant that includes pre-sowing treatment of seeds with Aquamix ST and subsequent treatment of vegetating plants in the budding phase. On average, over the years of research, the use of micro and macro fertilizers led to an increase in feed units and digestible protein with the yield of lupine grain. More valuable in terms of feed were the options that combine high yield with high grain quality. The greatest collection of digestible protein of 1.26 t/ha, feed units of 6.0 t/ha and exchange energy of 54.8 GJ/ha was provided by Aquamix ST in the variant with pre-sowing seed treatment and two treatments for vegetation. Potassium metaborate, used for the treatment of vegetative plants in the budding phase, showed almost the same results.

Testo completoAbstract (sommario):
The dietary selenium (Se) requirement has been determined for cobia Rachycentron canadum using purified diet; however, its role in the utilisation of plant-derived ingredients has not been evaluated in the species. Therefore, a 3 x 2 factorial experimental design involving three inclusion levels (0, 210 and 315 g/kg) of lupin Lupinus angustifolius kernel meal (LKM) and two concentrations (0 and 0.8 mg/kg) of Se was used to evaluate the effects of Se supplementation in conjunction with LKM on the growth, feed utilisation and physiological responses in the cobia. Six isonitrogenous (46.5 % crude protein) and isoenergetic (21 MJ/kg gross energy) diets were formulated and fed to cobia for 7 weeks in a flow-through seawater system. The results showed significant effects of Se supplementation and its interaction with dietary lupin on the growth and feed efficiency of cobia. Se supplementation significantly improved the growth and feed utilisation efficiency in cobia fed lupin-based diets. The nutrient digestibility of fish fed supplemental Se lupin-based diets was significantly higher than that of fish fed diets without Se supplementation at each inclusion level of LKM. There were no significant effects of dietary Se supplementation on the survival, muscle composition or muscle amino acids, whereas regression analysis indicated a positive linear relationship between tissue Se accumulation and dietary Se levels. An enhancement of haematological responses was also observed in cobia fed Se-supplemented diets. In summary, cobia fed lupin-based diets required higher dietary Se supplementation for higher feed utilisation efficiency than previously quantified for the casein-based diet.

Testo completoAbstract (sommario):
Two experiments were undertaken to determine the effectiveness of different S sources, in combination with flavomycin, fed with a lupin supplement, to increase wool growth and liveweight gain in 16-month-old Merino sheep fed wheat chaff. In the first experiment, ewes were fed wheat chaff (600 g/sheep) every day and the equivalent of 250 g/day of lupin grain twice weekly. An initial period of 7 weeks was used to quantify differences in wool growth and liveweight gain between individual sheep. Different S sources [2% gypsum, 12% fishmeal, 1.2% DL-methionine or 1.2% hydroxymethyl-methionine (Mepron)] were then added to the lupin grain with or without the addition of flavomycin and fed to sheep for a further period of 7 weeks. Wool growth was significantly increased (P < 0.05) only in the sheep fed lupin grain with the addition of fishmeal and fishmeal with flavomycin. Wool growth was significantly decreased (P<0.05) in the sheep fed lupin grain with the addition of gypsum or Mepron (+flavomycin). Liveweight gain was significantly increased (P < 0.05) in the sheep given methionine, Mepron or fishmeal. In the second experiment, ewes were offered wheat chaff ad libitum every day and the equivalent of 250 g/day of lupin grain twice weekly. After an introductory period of 2 weeks, different S sources (2% gypsum or 1.2% DL-methionine) were added to the lupin grain with or without the addition of flavomycin and fed to sheep for a period of 8 weeks. Wool growth was only increased (P < 0.08) in the sheep fed lupin grain with the addition of methionine with flavomycin. This treatment also resulted in a change in the pattern of chaff consumption. Liveweight gain was increased significantly (P < 0.05) in the sheep given gypsum, methionine or flavomycin. Poor quality feed supplemented with lupin grain appears to have sufficient N and S for wool growth. When sheep fed restricted amounts of poor quality feed are supplemented with lupins, increases in liveweight gain can be achieved with the addition of flavomycin, with or without S, to the lupins.

Tests results have been got on gray forest soil in the South-West of the Non-Chernozem zone of Bryansk region in the stationary experiment in the All-Russian Research Institute of Lupine in 2015–2018. The aim of the test was to evaluate a hectare of crop rotation area of four field lupin crop rotation (winter wheat – bare oats – winter triticale – lupin) for production of feed and energy effectiveness at different technics of the main soil cultivation. The variant of dump ploughing with deep loosening once in four years for lupin has the highest productivity of feed and energy effectiveness per a hectare of crop rotation area. Each crop of the crop rotation has high indices of yield and quality of grain products at this way of soil cultivation. The tested four-field lupin crop rotation is more energetically stable at the variant of the main soil cultivation — traditional ploughing with deep loosening. Efficiency coefficient of the crop rotation was 3.15 in the first cycle and the coefficient of energy effectiveness was 2.15. The other variants of the main soil cultivation could be used too in multiform farms of a region to provide quite high profitability.

Testo completoAbstract (sommario):
Poll Dorset x (border Leicester x Merino) lambs were removed at 3, 5, 7 or 9 weeks of age from their dams which were being fed drought rations of either wheat or oat grain with 0, 15,30,45 or 60% lupin grain (0.9 kg/ewe.day) and hay (0.3 kg/ewe.day). These weaned lambs were fed the same grain rations ad lib. until they were 17 weeks old and were also offered hay at 10% of the total ration. Survival of the lambs after weaning, had all lambs remained under treatments, would have been 75 and 25%, respectively, for lambs fed wheat or oat grain with no lupins and 75% for those fed lupins and weaned at 3 weeks. Increasing lupin content from 15 to 60% increased wool growth by 80 �m/day (P< 0.05) and liveweight at 17 weeks of age by 4.6 kg(P< 0.1) but did not affect feed intake. Efficiency of feed conversion to liveweight (FCR) was better at 15 and 60 than at 30 and 45% lupin content (P<0.05). Lambs fed wheat had higher intakes and liveweights than lambs fed oats, but their FCR was poorer (P< 0.05). Lambs weaned at 5 weeks and fed wheat were 7 kg heavier at 17 weeks than their counterparts fed oats, but this difference decreased with increasing weaning age to 1 kg for lambs weaned at 9 weeks (P< 0.05). Mean daily growth rates of lambs fed wheat and oats were 210 and 169 g/sheep respectively from 12 to 17 weeks (P< 0.05). I conclude that lupin grain is a desirable supplement for high cereal grain rations for early weaned lambs but it would generally be undesirable to wean the lambs at less than 5 weeks of age.

Testo completoAbstract (sommario):
In Europe, the most appropriate strategy to replace soybean meal (SBM) in animal feed has been the development of diets containing locally produced protein sources. One of these sources is lupine (Lupinus spp.). The effect of the total substitution of SBM by white lupine (WL) and yellow lupine (YL) seeds in the diets of growing rabbits and of gender on meat quality and the fatty acids (FA) profile were evaluated. Sixty hybrid weaned rabbits (New Zealand × Californian) (20 rabbits per diet), were fed diets that contained 150 g/kg of SBM (SBMD) and WL (WLD) or YL (YLD) for 35 to 69 days. At the end of this period, 30 rabbits (10 rabbits per diet) were slaughtered to evaluate the carcass and meat characteristics and the FA profile of the longissimus dorsi (LD) muscle. In general, the carcass and meat characteristics (pH and colour) were not affected (p > 0.05) by diet or gender. Further, there was no observed effect (p > 0.05) of gender on meat FA and on the calculated indexes related to human health. However, diet had an effect (p < 0.05) on the FA profile, FA categories, and calculated indexes related to human health. The meat from rabbits fed SBMD presented higher (p < 0.05) saturated FA (SFA; 44 vs. 39 g/100 g average on lupine diets) and lower (p < 0.05) polyunsaturated FA (PUFA; 24 vs. 28 g/100 g average on lupine diets). Our results showed that SBM may be completely replaced by WL or YL, improving the quality of LD muscle FA in terms of nutritional quality for humans.

In experiment 1, groups of Merino ewes, 4-6 years old, were given daily wheat chaff 500 g plus vitamin and mineral supplements, or wheat chaff 800 g and pelleted feed containing lucerne, lupin and barley 350 g plus mineral and vitamin supplements. Diets provided 0.5 and 1.2 times maintenance requirements. On each plane of nutrition, lupins 750 g were given or not given 10 days before oestrus. In experiment 2, the same planes of nutrition were used and sheep were injected daily with insulin 15 IU, or left untreated. Ovulation rate increased in response to lupin feeding at both planes of nutrition. Exogenous insulin, given as a daily single injection did not increase ovulation rate.

Abstract. The purpose is to establish the effectiveness of growing narrow–leaved lupine for grain in the conditions of the Sverdlovsk region. For the first time, new varieties of narrow-leaved lupin of the All-Russian Lupin Research Institute were used for ecological testing in these soil and climatic conditions in single-species crops when grown for grain. Research methodology and methods. The main method of conducting research was the laying of field experiments. Research in 2016–2017 they were conducted at the site of the Ural Research Institute, in 2021–2022 in the educational and experimental farm of the Ural State Agrarian University, located in the forest-steppe zone of the Sverdlovsk region. The main observations and records were carried out according to the methodology of the Institute of Feed. The yield was determined by the weight method with the selection of average samples. Results. In 2016–2017, 5 varieties of narrow-leaved lupine were studied: Raduzhnyy, Uzkolistnyy 53, Belozernyy 110, Smena, Vityaz’, and in 2021–2022, 3 varieties: Siderate 46, Bryanskiy kormovoy and Vityaz. All varieties of narrow-leaved lupine had side branches and beans on them before harvesting. The greatest number of lateral stems and beans was observed in the varieties Raduzhnyy and Vityaz’ in 2017 – 4.2–4.3 pcs. In 2016, the yield of narrow-leaved lupine grain from 1.13 to 1.54 t/ha was obtained on dark gray soil. In more favorable moisture conditions in 2017, the productivity of narrow-leaved lupine was 2-3 times higher than in the previous year in all varieties except for the Uzkolistnyy 53 variety. In acutely arid conditions 2021–2022 on podzolized chernozem, varieties of narrow-leaved lupine: Bryanskiy kormovoy, Vityaz’ and Siderat 46 provided grain yields from 1.34 t/ha for the Siderat 46 variety to 2.45 t/ha for the Vityaz’ variety. Scientific novelty. The effectiveness of growing new varieties of narrow-leaved lupine in the conditions of the Middle Urals was studied for the first time. Varieties have been established that allow obtaining high grain yields.

AbstractVehicle transportation represents acute stress to animals with release of catecholamines and glucocorticoids from the adrenal gland resulting in impaired metabolic state. Such changes in metabolism may be reduced by the application of suitable feed supplement. The aim of this study was to test the effects of lupin supplementation applied after 1-hour transportation. Ewes in the control group (n = 7) were fed on trefoil-grass silage and hay, while the diet of the experimental group (n = 7) was supplemented with lupin groats (Lupinus angustifolius, var. SONET; 500 g per head per day) for 8 days. In both groups, blood was collected on the day of transportation and on Days 6 and 11 thereafter. Total blood parameters were assayed using spectrophotometry and fractions of protein, cholesterol, and lactate dehydrogenase using agarose electrophoresis. Lupin increased the albumin: globulin (ALB : GLB) ratio and beta-hydroxybutyrate (BHB) concentration and reduced serum cholesterol and lactate, however it had no effect on body weight, body condition score (BCS), plasma glucose, serum protein, high-density lipoprotein (HDL), low-density lipoprotein (LDL), and very low-density lipoprotein (VLDL) cholesterol, lactate dehydrogenase (LDH) or alkaline phosphatise (ALP). Lupin may therefore be used as suitable feed supplement for sheep at times of high nutrient requirement.
