Large numbers of species of tree fodder are being used as green roughage source for goats in several farming systems. A study was carried out at Goat Research Station, Bandipur, Nepal in order to compare the feeding value of commonly used tree fodder leaves in mid-hills of Nepal. Altogether five treatments; tree fodder leaves of Ficus semicordata, Shorea robusta, Ficus glaberrima and Ficus lacor and mixed fodder as the conventional practices of the farmers were evaluated in Randomized Complete Block Design (RCBD) with three replications. Total of 30 male goats were used for the experiment in five groups, 6 for each treatment. The subsequent experiment was carried out to determine the nutrient digestibility of the tree fodder leaves by using fecal collection method. Nutrient composition, voluntary intake and nutrient digestibility of the fodder leaves and growth performance of goats were monitored. Crude protein (CP), total ash (TA), organic matter (OM), neutral detergent fiber (NDF), acid detergent fiber (ADF), acid detergent lignin (ADL), hemicelluloses and cellulose proportion were better for F. glaberrima and F. lacor leaves, whereas the digestibility of those nutrients were better for F. semicordata leaves and moderate for F. glaberrima and S. robusta. Voluntary fodder dry matter intake was highest for F. glaberrima and least for mixed fodders. Growth performance of goats was higher for F. lacor and F. glaberrima than other tree fodder leaves and mixed fodders. The leaves of F. lacor and F. glaberrima had shown better feeding value than the conventional practices of farmers, mixed fodders. The leaves of S. robusta and F. semicordata were observed similar with the mixed fodders for their feeding value.Int. J. Appl. Sci. Biotechnol. Vol 5(4): 442-448

Full textAbstract:
Researches have established that one of the main factors which increase the efficiency of animal production is to provide livestock with a sufficient amount of all types of quality fodder. It is proved that the deficiency of one of them or their nutrient components (protein, fat, carbohydrates, macro- and micronutrients, vitamins) significantly reduces the conversion of the entire diet into products. The suggested nomogram for planning forage crops area at different animal productivity enables to objectively forecast the volume of production of high-quality fodder and products. The intensification of the branch involves not only the optimal quantitative normalized ratio of fodders, but also their balanced nutrient density.
It is proved that the diet balance for nutrients is a crucial condition to show genetic potential of productivity by animals. We recommended classification for harvested fodder into balanced and unbalanced parts. The calculation formulas and corresponding coefficients were determined. The method was developed in order to manage forage production and rational use of the energy and protein resource of the harvested fodders, and also to determine means to prevent possible imbalance.
The energy-protein-balanced diets strengthens the health of animals, increases their productivity and the product quality.

Growing traditional green fodder requires a lot of land, but also grows with the absorption of large amounts of water and soil nutrients, depending on the metrological conditions in such cultivation. In this case certain costs of cultivation requires and the years when the sun was hot risk of burns. The influence of such factors one way to reduce the cultivation is by hydroponic method. During the study to plants nutrient transfer based on technology the following six types of hydroponic systems (HS) are considered: rising and falling water; HS in the nutrient solution; aeroponics; HS of aquatic crops; drip irrigation HS. At the same time, HS in the production of green fodder an overview of the design was made and their advantages and disadvantages are considered.HS is effective in the cultivation of green fodder nutrients as a technology the cultivation by transfer is. With this technology the cultivation of fodder grasses because it takes place in a closed system, feed solution into this system transfer automation is easy. Optimization of hydroponic feed technology for technological purposes trends control requires modernization of automation equipment (MAE).

Full textAbstract:
Application of hydroponic systems in feed production has not been extensively studied. Therefore, there is insufficient data on the effect of the slope of hydroponic growing trays used in the nutrient film technique on wheat fodder yield and its qualitative parameters. The slope of the trays has only been studied for food crops. This study conducted experimental research using a nutrient film technique hydroponic fodder growing device to evaluate the impact of growing tray slope angle on hydroponic wheat fodder production. The slope angle of the growing trays was changed from 2.0% (1.15°) to 8.0% (4.57°) with increments of 1.5% (0.86°). This research used two different light sources for wheat sprout illumination: indoor lighting (fluorescent lamps) and light-emitting diode illumination. In addition, two nutrient solutions were used for sprout irrigation: tap water and a solution enriched with macro- and microelements. Experimental studies confirmed the hypothesis that the slope angle of growing trays significantly affects the yield of wheat fodder grown for seven days. Analyzing the results, we found that the highest yield of wheat fodder after seven days of cultivation was achieved with growing trays sloped by 6.5% and using indoor lighting. In addition, we achieved the highest wheat fodder dry matter content using a 6.5% slope angle. Experimental studies also confirmed the hypothesis that using macro- and micronutrients in the nutrient solution does not significantly affect the yield of wheat fodder grown hydroponically for seven days.

Full textAbstract:
Leaf fodder from the trees is exceptionally rich in essential nutrients like crude protein, nitrogen, calcium, phosphorus, etc. as compared to grasses/dry crop by-products. Seasonal variation in macro and micronutrients concentration in the foliage of Albizia chinensis was studied from bud break (leaf emergence) to leaf abscission. In this species, N, P, K, Zn, Cu and Na contents decreased whereas Ca, Fe and Mn contents increased with the increase in leaf age and size with the advancement of season. Mg, S and Mo did not exhibit any particular trend. On the basis of the seasonal nutrient concentration variation, mid September to October is the optimum time for lopping the nutrient rich and maximum quantity of leaf fodder of this species.

This experiment was aimed to compare varieties and harvest time of green hydroponic fodder based on it’s quantity and quality. Green fodder is made from corn kernels, mung beans and unhulled rice. Green fodder was grown by mart hydroponics sensors and Arduino systems for controlling the water irrigation system and environmental conditions such as temperature and humidity. Quantity of green hydroponic fodder (corn, mung bean and unhulled rice) based on the biomass production. Quality of green hydroponic fodder based on nutrient content of the forage biomass (dry matter, crude protein, ash, ether extract, crude fiber and nitrogen free extract). Experimental design for fodder productivity was a completely randomized design with 3 x 3 factorial, i.e seed varieties (corn, mung bean and unhulled rice) and harvesting age of the green hydroponic fodder (7, 14 and 21 d). The results showed that total biomass was affected significantly (p<0.05) by harvesting age. Total biomass was increased with longer harvesting age of fodder. Corn green fodder and unhulled rice green fodder produce larger biomass than mung bean green fodder (p<0.05). The nutrient content of greenfodder were higher compared to the seeds. its quality and quantity, the best harvesting age of corn and unhulled rice green fodder was 14 days. Therefore smart hydroponic fodder can be an alternative to provide good quality fodder and land preservative.

The present study investigated the effect of different nutrient management practices on soil C fractions, growth and yield of fodder maize variety- African tall. The treatments were seven in number - T1: POP recommendation, T2: Soil test based POP, T3: Organic nutrient management using TOF-F, T4: POP + AMF, T5: Soil test based POP + AMF, T6: Organic nutrient management + AMF, and T7: Absolute control. Among the soil C fractions, highest TOC content was recorded by T3 which was on par with T5 and T6 and highest DOC content was observed for T1 at both levels of sampling depths. The soil labile and recalcitrant fractions followed same trend at both levels of depth of sampling i.e. T5 was found to be superior which was on par with T6. The highest value for shoot weight, root volume, green fodder and dry fodder yield was observed in treatment T5 which was on par with T4. The root weight was higher for organic nutrient and AMF combination treatment – T6 (50.23 g/plant). The results indicated an increased AMF activity in soil test based and organic manured treatments and inoculation with AMF resulted in better growth and yield of fodder maize in all the treatments. The correlation study indicated a strong positive correlation between labile and recalcitrant soil C fractions and fodder yield of maize giving an insight to the importance those C fractions in microbial growth, nutrient cycling, and plant growth.

Full textAbstract:
Taking note of the fact that bamboo is a source of income for poor in India including floodplain areas of Uttar Pradesh, present study was undertaken in Uttar Pradesh to assess the importance of utilizing bamboo as an important source of feed and fodder for livestock. Bamboo leaves and twigs, being palatable, can be chewed by cattle and it can be used as a nutrient rich green fodder and dry fodder for cattle in rural areas thereby reducing the consumption of expensive feed concentrates for livestock, poultry and fish. Under current societal regimes, very few people use bamboo leaves as a livestock fodder. Bamboo leaves and twigs and concentrates when used as a supplement yielded satisfactory results. Ensuring continuous supply of nutrient rich feed and fodder is critical to the agriculture, dairy and meat production and also fisheries. The present paper discusses the methods to explore the potential of bamboo as feed and fodder for livestock to improve the overall health and productivity of livestock.

The overall objective of this thesis work, in the Yucatán peninsula (México), was to establish a system with mixed woody species (leguminous/non-leguminous) to investigate the extent to which they increase nitrogen uptake and growth. The study tested the hypothesis that such mixtures may stimulate of N2 fixation from the atmosphere and the transfer of N from leguminous to non-leguminous plants. Three woody species were selected: Leucaena leucocephala (legume), Moringa oleifera (non-legume) and Guazuma ulmifolia (non-legume). More than 80% of planted seedlings survived and grew rapidly. Total biomass (fodder) production was 1.9-7.7 ton ha-1 for monocrops and 6-9 ton ha-1 for the mixtures. Nitrogen yield in the fodder was higher in the Leucaena+Guazuma mixture (285 kg N ha-1), followed by Leucaena monocrop and Leucaena+Moringa mixture (244 and 183 kg N ha-1, respectively). The δ15 N of samples from non-fixing species ranged from 2.7 to 3.2‰ (mean 3.0 ± 0.45‰). The δ15 N of L. leucocephala (0.8‰) was significantly lower, indicating that nitrogen fixation occurred in the Leucaena plants. The % Ndfa in the Leucaena mixtures ranged from 58 to 72% while in the Leucaena monocrop it was 69%, at 11 months old. Moringa leaves decomposed most rapidly, followed by Leucaena+Moringa, and, was best described by a double exponential model. The combination of Leucaena+Guazuma decomposed more slowly and pure Leucaena leaves decomposed at an intermediate rate. Over 16 weeks, Leucaena+Moringa released 65-75% of the initial N, Leucaena+Guazuma released 46-63%, and Leucaena leaves alone released, on average, 54% of their N. Lignin+polyphenols and tannins had a strong negative correlation with the rate of nitrogen release. The alteration of the decomposition and N release patterns observed when mixing plant materials of different quality provides good prospects for improving synchrony between N availability and plant N uptake.

The objective of this experiment was to evaluate the deposition, chemical composition, and decomposition of litter in a sabiá (Mimosa caesalpiniifolia Benth) canopy. The experiment was carried out at the Experimental Station of Itambé-IPA. The evaluation of existing and deposited litter was carried through the period of August of 2006 until July of 2007, every 28 days. Twenty squares with 1m² were used, in random points to each evaluation. The nylon bag technique was used for litter decomposition evaluation, incubating the following litter fractions: just-fallen leaves, “aging” leaves already deposited and in the beginning of the mineralization, and branches. The incubation periods were 0, 4, 8, 16, 32, 64, 100, and 256 days, being the same procedure carried through in 2006 and 2007. Treatments were distributed in randomized block design with five replications. Leaf deposition reached the value of 15,167 kg OM/ha, presenting greater deposition in the rainy period. Leaves represented the greater proportion of litter deposited, with average ratio of 87% of predominance in the majority of the evaluations. Branches and leaves presented average nitrogen concentration of 1.4% and 2. 7%, respectively, demonstrating that leaves were the maincontributors of nutrients via litter. The C/N ratio of leaves was below 30, branches presented C/N ratio between 30 and 40, likely favoring the nitrogen immobilization by ground microorganisms. The relationship between litter deposition and litter accumulation in the last month of evaluation was 0.30 indicating that it presented greater accumulation than deposition. In the decomposition assay, branches presented lesser mineralization than leaves both for total biomass and nitrogen, with leaf and branch decomposition varying with the incubation periods. The decomposition of substrata was influenced by the rainfall amount occurred in the evaluation period. In a general way, it was concluded that the litter component is essential in the process of nutrient recycling in a sabiá canopy, however, the mineralization occurs in relatively slow taxes, being this fact relevant in the reduction of nutrient losses by leaching, contributing for the maintenance of this ecosystem.
O objetivo deste trabalho foi avaliar a deposição, composição química e decomposição de liteira em um bosque de sabiá (Mimosa caesalpiniifolia Benth). O experimento foi realizado na Estação Experimental de Itambé-IPA. A avaliação de liteira existente e depositada foi realizada no período de agosto de 2006 a julho de 2007 a cada 28 dias. Foram utilizados 20 quadrados com 1m2, em pontos aleatórios a cada avaliação. Para avaliação da decomposição de liteira, foram utilizadas bolsas de “nylon”, sendo incubadas as seguintes frações: folhas recém-caídas, folhas senescentes já depositadas e no início da mineralização e ramos. Os tempos de incubação foram 0, 4, 8, 16, 32, 64, 100 e 256 dias, sendo o mesmo procedimento realizado em 2006 e 2007. Os tratamentos foram distribuídos em delineamento de blocos ao acaso com 5 repetições. A deposição de folhas atingiu valor de 15.167 kg MO/ha, tendo maior deposição no período chuvoso. As folhas representaram a maior contribuição na deposição de liteira, com proporção média de 87% predominando na maioria das avaliações. Os ramos e folhas apresentaram teores médios de nitrogênio de 1,4% e 2,7% respectivamente, demonstrando assim que as folhas foram os principais contribuintes de nutrientes da liteira. A relação C/N de folhas ficou abaixo de 30; os ramos apresentaramrelação mais elevada entre 30 e 40, favorecendo assim a imobilização de nitrogênio pelos microorganismos do solo. A relação entre a deposição e o acúmulo de liteira no último mês de avaliação foi de 0,30 indicando assim que houve maior acúmulo do que deposição. No ensaio de decomposição, os ramos apresentaram taxa de mineralização menor que as folhas tanto para biomassa total como para nitrogênio, tendo as decomposições de folhas e ramos variando de acordo com os períodos de incubação. A decomposição dos substratos foi influenciada pela quantidade de chuvas ocorridas ao longo do período de avaliação. De maneira geral, conclui-se que o componente liteira é essencial no processo de reciclagem de nutrientes em um bosque de sabiá, todavia a mineralização ocorre a taxas relativamente lentas, sendo esse fato relevante na redução de perdas de nutrientes por lixiviação, contribuindo para a manutenção desse sistema

The objective of this study was to evaluate the productivity and nutritional efficiency of hydroponic forage maize cultivated in whey as nutrient solution. The experiment was carried out in a greenhouse in an entirely randomized experimental design with six treatments and five replications and a control nutrient solution, conventionally employed in this type of cultivation. The other treatments were distributed in different levels of dilution of whey in tap water to get the concentrations of whey at levels of 20, 40, 60, 80 and 100%. Measurements of pH and EC were performed daily. The harvest was done 15 days after germination, being roots plus substrate separated from the shoots. The weight of fresh matter, dry matter, the levels of macronutrients (N, P, K, Ca, Mg and S) and micronutrients (Fe, Cu, Zn and Mn), in addition to Na and Cl of both the shoot and roots were determined. The increase in concentrations of whey promoted reduction in yield of hydroponic forage, increase in levels of N, S and Zn, decrease of K, Ca and Mg and no effect on levels of P, Fe and Cu in the shoot. The levels of P, K, Ca, Mg, S and Cu in the roots were increased. There was no effect on the levels of Zn and Fe.
O objetivo deste trabalho foi avaliar a produtividade e a eficiência nutricional da utilização do soro de leite aplicado como solução nutritiva no cultivo de forragem hidropônica de milho. Realizou-se o experimento em casa de vegetação em delineamento experimental inteiramente casualizado com seis tratamentos e cinco repetições, sendo o tratamento controle uma solução nutritiva convencionalmente empregada nesse tipo de cultivo. Os demais tratamentos foram distribuídos em diferentes níveis de diluição do soro de leite em água potável, avaliando-se as concentrações de 20, 40, 60, 80 e 100% de soro de leite. Durante o experimento foram realizadas medições diárias de pH e CE das soluções drenadas. A colheita foi feita com 15 dias após a germinação, onde se separou a parte aérea do substrato com as raízes. Determinou-se o peso de matéria fresca, peso de matéria seca, os teores de macro (N, P, K, Ca, Mg e S) e micronutrientes (Fe, Cu, Zn e Mn), além dos elementos que se mostraram em níveis tóxicos (Na e Cl), tanto da parte aérea como da parte radicular. O aumento nas concentrações de soro de leite promoveu redução na produtividade da forragem hidropônica. Observou-se com o aumento nas concentrações de soro de leite, acréscimo nos teores de N, S e Zn, com redução de K, Ca e Mg, além de não apresentar efeito nos teores de P, Fe e Cu, na parte aérea. Na porção radicular houve acréscimo nos teores de P, K, Ca, Mg, S e Cu não apresentando efeito nos teores de Zn e Fe.

Full textAbstract:
The climate on earth keeps getting warmer where heat waves, eutrophication, rising sea levels, extreme weather like flooding, droughts and wildfires are an expanding problem. The focus of this bachelor thesis is to determine the potential of mitigating eutrophication and while contributing to blue growth by harvesting and make use of reeds like Phragmites australis and Arundo donax. Reeds have the ability to quickly absorb nutrients from aquatic environments and there are opportunities to use them as a feedstock for producing biochar to be potentially used in areas such as soil improvement, fodder additive and carbon sequestration. Additionally, optimal biochar properties for the observed applications gets analysed. The thesis is based on a systematic literature review and an interview with Niclas Anvret at the non-profit organisation “Race for the Baltic”. Results show that biochar produced according to parameters such as heating rate, biomass species and especially, different temperatures, results in varied characteristics that change the biochar's adsorption abilities, nutrient retention, alkalinity, stability, surface area and porosity volume. The different applications of biochar are, however, not easily determined. This is because of the fact that certain biochar properties, that are prominent in entirely different pyrolysis conditions, could both be beneficial for the same application. Additionally, the different attributes sometimes influence each other which gives rise to unclear patterns affecting use potential. To overcome these issues, more research is needed to clarify the correlations between attributes of the biochar and to determine which characteristics of biochar are best suited for each application. In terms of how large-scale harvesting of reed could affect the ecosystem is also unclear, there is not enough research regarding the question to be able to draw clear conclusions. The reasoning behind this is that there are knowledge gaps, geographical differences, different unit measuring and methodology. The potential for biochar in the coal market is high and the demand in Sweden has risen over the past couple of years. There is also interest in using biochar as a soil amendment, to make use of nutrient content as well as applying organic matter to soils to potentially achieve long-term carbon sequestration. However, the production cost of biochar out of reed is relatively expensive, and it cannot compete with coal or other fertilisers/soil amendments on the market, with feedstock management usually being the most expensive part of production. Lastly, there is currently no harvesting method that can measure the amount of reed that needs to be harvested to be able to produce biochar on a large scale.Klimatet på jorden blir allt varmare och värmeböljor, övergödning, stigande havsnivåer, extrema väder som översvämningar, torka och bränder är ett stigande problem. Syftet med denna kandidatuppsats är att undersöka potentialen att mildra eutrofiering och samtidigt bidra till blå tillväxt genom att skörda - och använda sig av vass som Phragmites australis och Arundo donax. Vass har en framträdande förmåga att absorbera näringsämnen. Det finns därför möjligheter att använda dem som råvara för att producera biokol som potentiellt kan användas i områden såsom jordförbättring, fodertillsatser och kolbindning. Utöver detta undersöks optimala egenskaper för biokol enligt de observerade applikationerna. Kandidatuppsatsen bygger på en systematisk litteraturstudie och en intervju med Niclas Anvret på den ideella organisationen ”Race for the Baltic”. Resultaten indikerar att biokol, producerad i pyrolys enligt parametrar som uppvärmningshastighet, biomassa och i synnerhet olika temperaturer, resulterar i varierande egenskaper som förändrar biokolets absorptionsförmåga, bibehållande av näring, alkalinitet, stabilitet, ytarea och porositetsvolym. De olika tillämpningarna av biokol är emellertid svåra att avgöra på grund av vissa biokolegenskaper. Dessa egenskaper är framträdande under helt olika pyrolysförhållanden men kan samtidigt vara fördelaktiga för samma typ av applikation. Dessutom påverkar de olika attributen ibland varandra vilket ger upphov till komplexa trender som påverkar användningspotentialen. För att kunna dra tydliga slutsatser behövs mer forskning för att klargöra sambandet mellan biokolens attribut och för att bestämma vilken samling egenskaper hos biokol som passar bäst för varje applikation. Hur storskalig skörd av vass kan påverka ekosystemet är fortfarande oklart. Det finns inte tillräckligt med forskning kring frågan för att kunna dra tydliga slutsatser. Detta beror på att det finns kunskapsluckor, geografiska skillnader, olika måttenheter och metoder för de studier som gjorts inom detta område. Potentialen för biokol på kolmarknaden är hög och efterfrågan i Sverige har ökat de senaste åren. Det finns också intresse för att använda biokol för jordförbättring, dels för att använda näringsinnehållet men också för att applicera biokol i jorden för att potentiellt uppnå långvarig kolbindning. Dock är produktionskostnaden för biokol gjort på vass mycket kostsam och kan därför inte konkurrera med fossilt kol eller andra gödselmedel jordförändringar på marknaden. Detta beror främst på råvaruhanteringen som är den dyraste delen av produktionen. Slutligen finns det för närvarande ingen skördemetod som kan mäta den mängd vass som behöver skördas för att kunna producera biokol i stor skala.

Full textAbstract:
L’obésité est aujourd’hui un problème sociétal mondial. Dans les pays développés, l’abondance alimentaire a contribué au développement d’un environnement « obésogène » en favorisant la surconsommation. Ainsi, la promotion de choix alimentaires favorables à la santé représente un enjeu de santé publique majeur. L’objectif de cette thèse était de fournir une approche épidémiologique des choix alimentaires lors de l’approvisionnement et de la préparation des repas. Ce travail a été réalisé sur la population NutriNet-Santé, large cohorte prospective d’observation d’adultes français basée sur Internet.Au moment de l’approvisionnement, les logos d’information nutritionnelle ont été évalués comme des outils potentiels pour guider les consommateurs lors de leurs choix. Quatre logos ont été comparés : les Repères Nutritionnels Journaliers, les Traffic Light Multiples, le logo simple Pick the Tick et le logo 5-Couleurs. Des quatre logos testés, le logo 5-Couleurs était perçu comme le plus facile à identifier et celui demandant le moins d’effort à comprendre. Il était le plus efficace pour augmenter la capacité des individus à classer trois produits en fonction de leur qualité nutritionnelle. Enfin, en situation d’achats simulée en ligne, ce logo était celui qui permettait d’accroitre de façon la plus importante la qualité nutritionnelle du panier d’achat par rapport à une situation sans logo.Lors de la préparation des repas, un premier objectif était de comprendre l’ensemble des déterminants mis en jeu, cette thématique restant peu étudiée dans la littérature. Cinq grandes motivations ont été identifiées : alimentation saine, contraintes, plaisir, régimes spécifiques et organisation. Le fait d’attacher de l’importance à avoir une alimentation saine était associé à une alimentation de meilleure qualité nutritionnelle, ainsi qu’à une moindre susceptibilité d’être en surpoids. Attacher de l’importance à un régime spécifique était également associé à une meilleure qualité d’alimentation mais à un surpoids plus important. Malgré des associations significatives pour les autres motivations, les effets observés étaient de faible ampleur. Ces résultats soulignent l’importance de promouvoir des choix alimentaires favorables au moment de la préparation du repas.Le fait de planifier ses repas, c’est-à-dire prévoir à l’avance ce qui va être consommé sur plusieurs jours, a également été évalué. Globalement, les individus qui planifiaient leurs repas avaient une alimentation plus en adéquation avec les recommandations nutritionnelles et plus variée, bien que les résultats en termes d’apports en énergie et groupes d’aliments indiquaient de faibles différences. Ils étaient également moins susceptibles d’être obèses (et en surpoids chez les femmes).L’ensemble de ces résultats suggèrent l’intérêt de fournir des outils (logo, outils d’aide à la décision au moment de la préparation des repas et d’aide à la planification) afin de guider les individus lors de leurs choix alimentaires et ainsi améliorer la qualité de leur alimentationNowadays, obesity is a global societal problem. In developed countries, food abundance has contributed to the development of an "obesogenic" environment by encouraging overconsumption. Thus, promoting healthy food choices is a major public health issue. The objective of this thesis was to provide an epidemiological approach to food choices during grocery shopping and home meal preparation of food. This work was performed on the NutriNet-Santé population, which is a large web-based prospective observational cohort of French adults.During grocery shopping, front-of-pack nutrition labels were evaluated as potential tools to guide consumers in their choices. Four logos were compared: the Guideline Daily Amounts, the Multiple Traffic Light, the simple Pick the Tick label and 5-color nutrition label. Among these labels, the 5-color nutrition label was perceived as the easiest to identify, and that requiring the least effort to understand. It was the most effective in increasing the capacity of individuals to rank three products based on their nutritional quality. Finally, in a situation of simulated online grocery shopping, this label was the one that allowed the most important increase in the nutritional quality of the shopping cart as compared to a situation without label.During home meal preparation, a first objective was to uncover all the determinants involved in food choices, since this topic remains little studied in the literature. Five motives of dish choice were identified: healthy diet, constraints, pleasure, specific diets and organization. Giving importance to a healthy diet was associated with a better nutritional quality of food, and to lower odds of being overweight. The importance attached to specific diet motive was also associated with better diet quality food but lower odds of being overweight. Despite significant associations for other motives, the observed effects were relatively small. These results underscore the importance of promoting healthy food choices when preparing meals.Planning meal, in other words deciding ahead the foods that will be eaten in the next few days, was also evaluated. Overall, individuals who planned their meals were more likely to comply with nutritional guidelines and had a more varied diet, although the results in terms of energy intake and food groups showed limited differences. They were also less likely to be obese (and overweight in women).All these results suggest the interest of providing tools (nutrition labels, tools providing assistance for decision-making when preparing meals, as well as for meal planning) to guide individuals in their food choices and thereby improving the quality of their diet

Full textAbstract:
The livelihood of Nepali farmers in mid-hills Nepal is interrelated to forest-livestock-farming system. Farmers go to the forest to take fodder as feed for livestock then the livestock products are used for their consumption and income sources. The fresh manure is utilized as fertilizer for crop farming as farm yard manure (FYM). However, the nutrient relationship among fodder, manure, and farm yard manure has not been clearly understood. In addition, the monetary value of the nutrient of FYM has not been quantified. The aim of this study is to evaluate the importance of fodder trees as a source of soil nutrition. To achieve this, this study has the following objectives: 1) to examine the nutrient status in commonly-used fodder trees, 2) to determine the nutrient status of fresh manure from livestock feeding on different fodder trees, 3) to survey the use and quality of farm yard manure, and 4) to determine the equivalent market value of the nutrients in farm yard manure. This study explains the results of analysis identifying the concentration of Nitrogen (N), Phosphorus (P) and Potassium (K) in four forest fodder species. Additionally, it analyses the nutrient composition (NPK) of the manure of five goats, cows and buffalo feeding on three types of fodder species over a 27 day cycle. Finally, it calculates the monetary value of the nutrients in both fodder and manure. The nutrient content of each fodder species is different for each village and according to livestock type. The nutrient content of fresh manure produced by different fodder types also differed in K concentration (for cows) and in P and K concentrations (for buffalo). This study shows that Quercus is a promising fodder for cows and buffalo, along with Ficus fodder also for buffalo. Furthermore, the P concentration in FYM differed for each village. Lastly, an analysis of the equivalent monetary value of FYM determined that it is five to ten times less than the market value of FYM traded.Thesis (M.Phil.) -- University of Adelaide, School of Agriculture, Food and Wine, 2016.

This research was conducted at the University of KwaZulu-Natal, Pietermaritzburg, South
Africa. The research encompasses five different studies to assess nutrient cycling in intensive
and extensive grazing systems with a view to optimising livestock production.
The first study was designed to assess the effect of teff-lucerne mixtures on teff, lucerne and
teff-lucerne mixture yields. Lucerne and teff-lucerne mixtures benefited from the association.
The overall soil N content of the teff-lucerne mixture plots was greater than the teff alone
plots.
The second study focused on teff-leucaena association evaluation. It had two leucaena plant
row spacings as treatments, 180cm and 120cm, respectively. Teff grown in mixture with
leucaena produced a total teff dry matter (DM) of 7931.57 kg ha¯¹ for the 180cm row spacing
and 8329.57 for the 120cm row spacing compared to the 3548.93 kg ha¯¹ of DM obtained
from the teff alone treatment. The teff-Ieucaena stand also had a greater DM yield response to
leucaena row spacing compared to the teff alone. In terms of nutritive quality, all stands from
the teff-leucaena plots were better than the quality obtained from the teff alone plots. Total N
content of teff from the l80cm row spacing was 21.83 g kg¯¹ and that from the 120cm 16.07 g
kg¯¹ compared to the total nitrogen (N) content of 19.77 g kg¯¹ of the teff alone treatment. The
total phosphorus (P) content was 2.73, 1.96 and 2.07 g kg¯¹ for the 180cm, 120cm and teff
alone treatments respectively. However, the total soil N content was higher for the teff alone
plot than for the teff-leucaena plots, which are 1.91, 1.48 and 100 g kg¯¹ for the teff alone,
180cm and 120cm treatments respectively.
The third study was designed to assess the effects of different N fertilizer application rates on
teff yield response. The rates applied were 0, 50, 100 and 150 kg N ha¯¹. There was significant
difference in teff response of the three N fertilizer application rates compared to the control
and teff DM yield response was lower for the 150 kg N ha¯¹ (838 kg ha¯¹) treatment compared
to the control (553 kg ha¯¹).
Both teff DM and nutritive value were higher in the plots treated
with N fertilizer than in the plot which received no N fertilizer (control). The soil N content
was also higher in those plots treated with N fertilizer. Study four was conducted on the Department of Grassland Science's grassland management
techniques trial field at Ukulinga. The effects of nutrient cycling under different management
techniques such as burning, mowing and grazing on grass yield response, plant quality and
soil nutrients were assessed. However, the response of grass DM yield and P content was not
significant but the three treatments had a significant effect on grass N content. Their effect on
soil N content was also significant and the grazing plot had the greatest soil N levels.
The last study was conducted in the rural areas of Okhombe and Zwelitsha to assess the
effects of grazing intensity on grass yield response, plant quality and soil nutrient status at
different distances from homesteads. Grass DM yield and nutritive value declined when
distance from the homestead increased. The soil N content also was higher nearer to the
homestead than further away.
Most farmers, particularly in developing countries including those in Eritrea, often experience
that their animals prefer forages from some plants such as lucerne, leucaena, and other
indigenous leguminous plants. They also observe that they get greater yield from crops grown
near leguminous plants or in rotation with legumes. They are also still using manure from
their animals to fertilize their croplands. Therefore, it is still the duty of the researchers to
demonstrate to farmers on farm studies to convince farmers that it is because leguminous
plants have the ability to add quality and quantity to the feed of the animals and soil nutrients
to the croplands. Hopefully, this study will convey to farmers the use of growing integrated
grassllegume pastures and crops, and illustrate that livestock have their own role in
transporting nutrients and hence use them as good means of distributors of soil nutrients.Thesis (M.Sc.)-University of KwaZulu-Natal, Pietermaritzburg, 2004.

Full textAbstract:
Since the Green Revolution era, the farming sector exploited the soils for food, fiber, fodder, etc., with high input responsive varieties that excavated vast amounts of chemical fertilizers. The burgeoning population of the country calls for a commensurate increase in food production to satisfy the demands of its inhabitants. Further, due to innovative mechanization in agriculture, specialization, and government policy programs, the productivity of food has soared. Subsequently, it ensued greater productions and minimized food prizes. Regrettably, intensive agricultural operations degraded the soil quality and now reached such a stage where without external inputs, growers unable to achieve their targeted yields. India has lost 68% innate productive capacity of agricultural soils. This plunder of land’s quality continues unabated, further resulting in low nutrient use efficiency and insufficient yields of agroecosystems. Therefore, this is high time to realize the dreadful impacts of intensive crop production on the natural ecosystem. Irrefutably, both soil and its nutrients are the wondrous gifts of nature to humankind; utilizing them sustainably is imperative. The present chapter highlights the impacts of non-judicious nutrient management on soil productivity, nutrient use efficiency, and novel technologies required to promote sustainable agriculture and achieve the target of doubling farmer’s income in India.

Full textAbstract:
The major bottleneck of dairy effluent treatment plant operation is the generation of 10 m3 of nutrient rich wastewater per m3 of milk processed resulting in an annual production of 7.93 tons of carbon dioxide equivalent (CO2 e) gas during treatment in a 7–8 step process. It is an expensive, non-ecofriendly, laborious process which is often not adoptable by the small segment installations. A carefully selected tailor-made bacterial consortium in biofilm reactor within 4 h of incubation in a single step operation under ambient condition could transform the total volume of wastewater into ammonia rich liquid biofertilizer generating 0.79 tons/year CO2 e gas. This biofertilizer replaces the use of fresh water and chemical fertilizer for agriculture, producing economic crops at par with chemical fertilizer. In certain cases, the production of crops is increased substantially over chemical fertilizer based growth. It reduced carbohydrate content of tuber crops. The generated liquid biofertilizer can overcome the shortage in fodder production without using chemical fertilizer and fresh water, hence solving one of the major concerns for sustaining the expansion of dairy industry, hence making dairy effluent treatment plant (ETP) operation an eco-friendly, self-sustainable operation.

In agriculture, according to the data of the statistical collection, the production of grain crops occupies a large part. At the moment, much attention is paid to the study of perennial crops: Gray Wheatgrass (Latin Thinopyrum intermedium), Trititrigia (Latin Trititrigia cziczinii Tsvelev). These crops help slow soil erosion and minimize nutrient leaching. The non-cereal part of cultivated plants is an important reserve for strengthening the fodder base of animal husbandry and expands the range of sources of raw materials for the microbiological industry in the production of fodder proteins. The article provides an overview of technologies and equipment for harvesting grain crops, with the help of which one of the optimal methods of harvesting perennial grain crops, the stripping method, can be distinguished. This method reduces grain trauma and allows harvesting crops in the early stages of ripeness, when the grain contains more nutrients than fully ripe, and the grain has a strong bond with the stem.

Global growth is predicted to reach about 10 billion people in 2050 and 66% of this population will be concentrated in urban areas. As the world population, the need for food and feed for livestock is also increasing [1]. However, due to climate change, urbanization, and water scarcity, it is becoming difficult to improve the conditions of agricultural production for better yields. Therefore, traditional farming seems unable to maximize the quality and amount of produced crops [2]. Hydroponic is a great alternative for feed scarcity, it involves producing green fodder without soil in a closed environment and harvested after a short period 6-10days. This technology is gaining importance as it can guarantee a continuous and high yield of green forage around the year for livestock feeding. Seed in hydroponic cultivation can be the most important input and compared to the conventional system can present more than 80% of the total cost [3]. Livestock farmers can proceed with small- or large-scale hydroponic production systems using low-cost or high-tech devices for sustainable and profitable livestock production. In this study, we aim to explain six types of hydroponic systems based on plant nutrient supply technology: Wicking system, deep water culture DWC, drip system, aeroponics; ebb and flow system and nutrient film technique (NFT). In addition, we will review the advantages and disadvantages of hydroponic fodder production system and its hi-tech or low-cost applications.

The unregulated use of mountain fodder lands has led to the degradation of soil and vegetation. The use of the biologically active drug "Extrasol", zeolite-containing agro-ore and humus of sheep manure on the natural forage land of the mountain zone contributed to a change in the composition of soil nutrients by reducing the acidity of the soil solution. The germination of fallow seeds of cereals increased from 30.4 to 55.3%, legumes from 5.2 to 17.1-26.8%, which had an impact on the reduction of weed forbs from 64 to 27.6-19.5 %. The change in the structure of the herbage contributed to an increase in yield from 9.9 to 69.4 c/ha of dry weight, the concentration of feed units from 0.9 to 6.1 thousand feed units and MA to 73.9 GJ/ha, allowing to increase the load livestock on pasture and its productivity, while maintaining the ecological stability of mountain agricultural landscapes.

Full textAbstract:
Feeds and animal nutrition presents a major sector in providing food security. However, there is a large gap between fodder supply and demand [1]. This gap can be attributed basically to climatic changes, urbanization and increase in meat demand. Nowadays, especially after the covid-19 pandemic, there is a crucial problem in supplying fresh green feed to remote and urban regions. Hydroponic fodder is an alternative solution to provide the sustainability of quality forage for ruminant. Hydroponics can include several crops such as maize, wheat and barley, the fodder can be produced in a short duration (6-10 days) and all year around. The hydroponics fodder present various benefits for animal health. Feeding hydroponically produced fodder increases the digestibility of the nutrients in the ration, which could increase milk production [2]. Hydroponic fodder production is an economic solution particularly where the conventional production of green fodder is limited or unavailable. This technology put forward a solution to address the shortage of forage production caused by the scarcity of green feed in dry seasons and urban areas [3]. That´s why, further studies and academic efforts are needed to expand hydroponic fodder production. The purpose of this study is to review the actual literature on hydroponic fodder production process, nutritious value and effects on livestock production and productivity.

On the production paddocks of the Mayskoye cattle farm of the Kaliningrad Research Institute of Agriculture from 1997 to 2000, over 4 years of use, the productivity of a superficially improved pasture due to the overseeding of perennial legumes and cereal grasses increased and amounted to 61.0–65.2 c/ha of dry matter, 70.2–73.7 GJ metabolic energy, 7.4–8.9 c/ha of digestible protein. Compared to grass stands, the energy intensity of nutrients decreased by 5–6 times when high doses of nitrogen were applied. The content of clovers in the pasture herbage remained at the level of 40–50%, which fully ensures the high productivity of legume-grass pasture herbage due to biological nitrogen and corresponds to the goal of the research.

The control group received compound feed without rapeseed seeds. The first and second experimental groups included 7.5% by weight of mixed fodder native rapeseed seeds of Zarya and Nadezhda varieties, which were used to replace part of soybean meal and sunflower oil. The content of nutrients in mixed feed complied with the regulatory requirements. The oil was balanced in composition: a large amount of monounsaturated, low-saturated fatty acids, a moderate amount of polyunsaturated fatty acids. It has been established that compound feeds with rapeseed seeds do not negatively affect the live weight gain of experimental broiler chickens. On the 39th day, the live weight of chickens in the control, in the first and second experimental groups was 2.250, 2.245 and 2.256 g, respectively. The significance of the difference in this indicator with the control group has not been established (P > 0.05). In the study of blood serum in chickens of the first experimental group, an increased level of bilirubin and the enzyme glutamyltransferase was revealed, which indicates stagnation of bile in the bile ducts (P > 0.01). The efficiency of growing poultry using rapeseed seeds was higher than in the control, which is associated with a decrease in feed costs for obtaining meat products and a lower cost of experimental feed.

Full textAbstract:
In industrial fish filleting, around 30–70 % of the total weight of the fish end up as side streams (often called by- or co-products), such as the head, backbone, caudal fin, skin, and intestines. Currently, these fractions are dedicated to low value uses as fodder meals or mink feed, even if they contain significant amounts of protein, long chain (LC) n-3 polyunsaturated fatty acids (PUFA), and other nutrients such as vitamins and minerals. However, most fish processors mix their side streams, not least when it comes to small pelagic species like herring. This practice limits use of the side streams for food production since the raw material gets very complex, and since blood, enzymes and lipids from e.g., the viscera and head parts easily contaminate the cleaner parts like the backbones and tails, accelerating e.g., their oxidative or enzymatic degradation. In the present study, lipid oxidation in ice-stored sorted and minced herring fractions (head, backbone, viscera+belly flap, tail, fillet) from spring and fall, and its association with endogenous pro-oxidants, antioxidants and lipid substrates were investigated. Peroxide value (PV) and thiobarbituric acid reactive substances (TBARS) had increased significantly in all fractions after 1 day, but for both seasons, the most rapid PV and TBARS development occurred in head, which also had highest hemoglobin (Hb) levels and lipoxygenases (LOX) activity. Viscera+belly flap was overall the most stable part, and also had the highest -tocopherol content. Pearson correlation analyses across all five fractions confirmed a significant impact of Hb, LOX and -tocopherol on the lipid oxidation susceptibility, while content of total iron, copper, lipids or PUFA provided no significant correlation. Overall, the study showed which pro-oxidants that should be inhibited or removed to succeed with value adding of herring filleting side streams along with the fillet itself.
