Full textAbstract:
In the practice of feeding poultry enzyme drugs are widely used that contribute to the effective transformation of feed components into poultry products. Reducing the cost of compound feed for poultry due to the introduction of enzyme drugs is of great interest, both from a scientific and practical point of view. More than 2/3 of phosphorus in plant feeds is represented in the form of phytate and in this form the element is only partially absorbed in the poultry body. Accordingly to cover the need for phosphorus in plant diets include inorganic phosphates, animal feed and the enzyme phytase (breaks down phytate). This makes phosphorus the third most expensive feed component after energy and protein. The purpose of the researches was to study the effectiveness of using super dose commercial phytase in feeding of turkey poults. The results of research on the use of high doses of phytase in the diet of turkey poults of cross Hybrid Converter have been presented. It has been found that the use of compound feeds containing the super dose of phytase in the rearing of broiler turkey poults does not have a negative influence on the zootechnical indicators of poultry rearing, meat productivity, and increases the economic indicators of meat production. The results on base the experiment, economic indicators have been calculated. It has been found that the cost of 1 ton of compound feed consumed in the experimental group was less than in the control group by 166,28 rubles or 0,7 %. The use of high doses of phytase in the diet of turkey poults of the experimental group allowed to reduce the cost of growth of 1 kg of live weight by 4,7 % and increase the profitability of meat production.

Since the digestive system of poultry is quite short, the residence time of the feeds in the digestive system is also short. In addition, many poultry species have a low ability to digest and utilize cellulose, cellulose fractions (ADF and NDF) and non-starch polysaccharides. Therefore, it becomes necessary to use more expensive feeds with high nutrient content in poultry nutrition. This situation raises the prices of animal products such as white meat and eggs. In order to turn this disadvantage in poultry feeding into an advantage, alternative poultry with a stronger digestive system, better digestibility of cellulose-rich cheap feed sources and better utilization of roughage are needed. When evaluated in terms of its characteristics, it will be seen that one of the poultry that can better benefit from cheap feed sources is goose. The efficient use of cellulose-rich feeds, such as goose, reduces feed costs and provides a suitable opportunity to produce cheaper poultry products. Encouraging goose production can be an important source of income and livelihood, especially for the rural population. It is thought that goose breeding can be an important alternative for white meat and egg production because it benefits from cellulose-rich feeds better than other poultry. In this review, the microbial digestion properties of geese, their ability to benefit from cellulose fractions, especially cellulose, and non-starch feed elements were examined.

Full textAbstract:
To assess the contamination and potential health risks for poultry, we investigated concentrations of selected mycotoxins in complete feeds sampled within the period of 2013–2018 in the Czech Republic. Broiler feeds, feeds for laying hens, chickens and/or other poultry species were investigated by ELISA methods or chromatography. Our results demonstrated that unlike other mycotoxins, (such as aflatoxins, ochratoxin A or zearalenone), deoxynivalenol (DON) may represent a potential threat. The prevalence of this mycotoxin in all the feed categories was very high, always reaching at least 81.29%. Moreover, in 14 of the 139 analysed broiler feed samples (i.e., in 10.81% of samples), DON was detected in concentrations exceeding the recent guidance value of 5 000 µg/kg established by EU legislation. Since previous studies demonstrated that the long-term feeding of such a highly contaminated diet could cause stress in the animals and could lead to their growth suppression, good agricultural practices and the further systematic monitoring of Czech poultry feeds are still highly needed.

AbstractThe shortcomings of current feeding practices for meat poultry are illustrated and alternative systems discussed. These include automatic blending between high and low protein feeds at each poultry house, to deliver appropriate predetermined nutrient intakes daily. The benefits of using whole cereal as the low protein feed on gut pH, viscosity of gut contents, nutrient digestibility, litter quality and reductions in atmospheric pollution, and coccidial damage are discussed.Comparisons between current ad-lib feeding and various developmental stages of “Automated Controlled Feeding” are made. The alternative systems lead to proper function of birds' gizzards and crops and the benefits in terms of bird health, reduced mortality and variability, improved behaviour, and feed efficiency are illustrated.Currently available integrated management systems are described, and the principles behind a current MAFF LINK project discussed. This involves a real-time growth model that uses recorded liveweight, feed and nutrient intakes to date, to calculate the next day's nutrient intakes that will get birds back on target if they start to deviate from it.Future developments where the objective function could include minimising costs per kg liveweight or breast meat or maximising margin per bird placed or per square metre per year are discussed.

The article deals with the possibility of using feed additives in the feeding of broiler chickens and the peculiarities of their effect on the poultry organism. Contemporary data on the biological role of nutrients and energy in the feeding of broiler chickens are presented. The characteristics of the main feeds for poultry and the ways of reducing their prime cost in the conditions of broiler farms are given. The basic principles of effective feeding of poultry with forages of different content of metabolic energy and crude protein are considered, taking into account their assimilation in the body. Provided compound feed recipes and practical tips. It is established that high growth rate of broiler chickens in the start and groove periods (5–39 days) is provided by high-protein compound feeds – 23% (1–2 weeks), 21% (3–5 weeks) and exchange energy of 298 kcal and 305 kcal, respectively. With further cultivation in the finish forage the protein content in the forage decreases and the level of metabolic energy increases (up to 309 kcal). However, for each cross applies its own technology of cultivation and different rates of nutrients in raw materials. It is clear that effective breeding of broiler chickens is not possible without the proper rationing and use of protein and feed energy. Of course, provided that the supply of biologically active substances also corresponds to the normalized amount. Thus, the quality of poultry products is directly dependent on the quality of feed and the efficiency of transformation of feed energy into products.

Fibrous feeds mostly of crop residues, green grasses, and tree foliages and leaves support bulk diets of farm animals being raised mostly by smallholders. The roughage DM produced (51056 million kg) surpasses its demand (49200 million Kg) by 3.77%, but losses and otherwise uses result in production deficit of 44.5%. An average 56.2% deficit of roughage DM and 80.0% of concentrate DM results in a very poor plane of nutrition for farm animals. It supports an average diet containing 6.75 MJME/Kg DM and 1.63% DCP with the feed produced or 7.74 MJME/Kg DM and 2.32% DCP with the feed available, while a miserly calculation demands an average diet of at least 6.50 MJME/ Kg DM and 4.50% DCP. Brans and oilcakes sharing the bulk amount of concentrate feeds, except cereal maize being produced recently, often limit options for formulation of diets of higher metabolizability and quality protein including balancing of micronutrients essential for supporting nutritional planes for high yielding animals. Annual biomass demand and supply mismatch, harvest loss, bulk transfer problem, and otherwise uses of fibrous residues further limit feed supply to animals irrespective of their quality. Commercial poultry, on the other hand, is largely based on imported feeds except a part of corn. Different form of premixes, steroids, antibiotics and enzymes with or without knowing their quality and residual impacts on human health also used for poultry and bovine animals posing threats to food safety sometimes. The present poor plane of nutrition is not conducive to support an increased production of local or crossbred animals. Diversification and production of quality feeds and fodders, synchronization of feed production and availability to animals, strengthening feed milling capacity, conservation and improvement of new pasturage systems, mitigation of climate change impacts and domestic protection to feed safety and quality feed import are some of the options forward to increased supply of feeds and fodders help increased production and productivity of farm animals in the country.DOI: http://dx.doi.org/10.3329/bjas.v43i1.19378 Bang.

Particularly in the fruit juice industry, the remaining peels and pulp parts are not available for human consumption after the juices are used. It is possible to evaluate these wastes by adding them to poultry feeds. A number of studies have been conducted by researchers on the nutritional value of many fruit wastes and on the performance of poultry. Natural antioxidant content has been reported to have a positive effect on growth, microbial and immunological parameters when high fruit peels are used as feed additive in poultry feeding.

Poultry farming is a highly profitable and not capital intensive agricultural project. It is becoming one of the highest investments in agriculture in Nigeria. The proliferation of self -produced feeds by the Farmers with the addition of some minerals to stimulate growth could elevate the levels of radionuclides in feeds. This, therefore, calls for the determination of the health effects from the consumption of these chicken meats and organs. 10 samples of broilers and 30 feed samples (10 each of Starter, Grower, and Finisher feeds used in feeding the chicken) were used; collected from five selected poultry- farms in Lagos State, Nigeria, and analyzed using spectrometry analysis with NaI (Tl). The results obtained showed that concentrations of 40K, 232Th, and 226Ra were 49.0±25.8, 24.9 ±12.2, and 32.9 ±16.2 Bqkg-1 respectively, in chicken meats. In the feeds, their values were below the UNSCEAR recommendation. The annual effective doses in chicken meats and organs were lower than the 70µSv/yr limit. The cancer risk was within the recommended limit, and the internal hazard indices were below unity. The mean values of the transfer coefficient (TC) were also below 1 for 40K, higher than unity for 226Ra in Finisher feeds, and 232Th in Starter feeds. The starter and finisher feeds were moderately contaminated. So, feeding chicken with these feeds may expose the consumers to the danger of over-exposure to 226Ra and 232Th.

Soybean meal and grain corn are feedstuffs that normally used as the main ingredients in poultry feeds as a source of protein and energy in tropical countries. The availability of these feedstuffs for broiler nutrition nowadays is becoming more competitive. Thus, food security, especially in the developing countries, would be susceptible. Currently, efforts are being made to use alternative feedstuffs as a sustainable feed resources to substitute portion of soybean meal and grain corn in poultry diets due to their high price since both of the raw material were imported. In Malaysia, usage of PKC is common in ruminant diets, but limited in the non-ruminant diets especially in poultry diets due to the high fiber content of PKC. Several works have been conducted to increase the nutritional contents of PKC as one of the measures to reduce and/or eliminate the constraints of utilizing PKC in poultry diets. The method used to achieve this target is either through physical, chemical, biological or combination of these treatments. This paper discusses the use of PKC as the sustainable feed resources that can be incorporated in the poultry feeds. Hence, emphasis should be given to improve nutritional values of PKC in order to reduce feeding cost of poultry.

Small ruminants, such as sheep (Ovisaries) and goats (Capra hircus), contribute to approximately 475 million metric tons of carbon dioxide equivalent (MtCO2e) greenhouse gas (GHG) emissions, accounting for approximately 6.5% of the global emissions in the agriculture sector. Crop residues, silage, grasses, hay, browse, plant leaves, shrubs, agro-industrial by-products, poultry litter, and other alternative feed sources are frequently utilized for small ruminant production. The use of these valuable alternative feeds can significantly improve animal productivity and reduce carbon footprints and GHG fluxes, making it both environmentally friendly and cost-effective. Additionally, these alternative feeds possess antioxidant, antimicrobial, and antiseptic properties that can enhance the quality of the meat and milk produced. By impacting the bacteria involved in ruminal biohydrogenation, alternative feeds can reduce methane emissions and contribute to a decrease in the carbon footprint. Overall, the use of alternative feed sources for small ruminants generally improves their apparent nutrient digestibility and productivity, and has an impact on the production of greenhouse gases, especially methane. Finally, this review recommends evaluating the economic analysis of reducing methane emissions in small ruminants by utilizing different feed sources and feeding techniques.

Poultry production is an important area of the agricultural economy. Nowadays, there is an interest in novel sources of feed additives that will improve production performance and poultry health. As an easily available and renewable biomass rich in biologically active compounds, seaweeds can meet this demand. Different forms of seaweeds–seaweed powder from naturally occurring biomass, cultivated or waste biomass, extracted compounds, post-extraction residues or liquid extracts–may be used in poultry feeding. Inclusion of this unconventional material in the poultry nutrition can positively influence the poultry performance along with its health and enrich poultry products with active compounds, such as micro- and macroelements, polyunsaturated fatty acids and pigments. Seaweeds also reduce lipids and cholesterol in eggs. Moreover, due to their unique properties, they can serve as an alternative to antibiotic growth promoters. This review presents the latest developments in the use of seaweeds in poultry nutrition, as well as its limitations.

Full textAbstract:
Distillers dried grains with solubles (DDGS) is a coproduct of corn-based ethanol production that can be a valuable source of energy, digestible amino acids, and available phosphorus in poultry feeds. Dietary incorporation of DDGS reduces the amount of primary ingredients such as corn and soybean meal needed to formulate poultry diets, improving the sustainability of both biofuel and poultry production. The nutritional value of DDGS has been extensively evaluated since it became increasingly available to feed producers in the early 2000s, but evolving methods of ethanol production and coproduct fractionation necessitate its continued characterization. Attempts to relate nutrient utilization of DDGS to its chemical composition have revealed that fiber content is a primary determinant of dietary energy value of DDGS for poultry. Distillers corn oil, which is extracted from thin stillage during production of distillers grains, can also be supplemented into poultry diets as an energy-dense lipid source in place of animal fats or other vegetable-based oils. Poultry feeding practices in the United States are also evolving, including increased adoption of all vegetable-based diets and reduced use of in-feed antimicrobials. Therefore, further characterization of both the nutritional value of DDGS and its impact on gastrointestinal health will support its continued use in poultry diets.

The use of safe, natural feed additives in animal feeding is becoming increasingly important to provide animals with biologically active substances, reduce the risk of chemicals being transferred to the end consumer through products, their accumulation, and increase productivity. The purpose of the study was to determine the effect of Artemisia capillaris on egg productivity of quail hens. To conduct the experiment, 4 groups were established – a control group and three experimental groups, 72 animals (♀60+♂12) in each. The experiment, which lasted 210 days, involved feeding poultry with complete balanced feeds that had the same chemical composition and differed only in the content of the test additive, which was introduced into the feeds of poultry of experimental groups 2,3, and 4 in the amount of 0.5%, 1.0%, and 1.5% by weight of the feed, respectively. The introduction of dry wormwood powder in mixed feed of quail hens in the amount of 0.5-1.5% has a positive effect on such indicators of egg productivity as the gross yield of eggs, which increased in the experimental groups by 2.6-5.6%, the egg weight increased by 5.6-12.9%, while feed costs decreased by 2.8%. According to the qualitative indicators of eggs, there was an increase in the absolute weight of yolk by 3.0-8.3%, albumen by 2.6-6.5%, shell by 0.6-1.2%, and a decrease in the egg index by 0.9-4.1%. Feeding A. Capillaris to poultry leads to an increase in the content of palmitic, stearic, oleic, linolenic, eicosanoic, and arachidonic fatty acids in egg yolk by 0.01-6.07%. The optimal level of A. Capillaris in the diet was determined to be 1.0% of the total weight of the feed; this amount had a positive effect on the above indicators, increasing them, which can be used in the industrial technology of quail eggs production, and in organic production

The article highlights current data on the biological role of the most crucial feed nutrients - protein and lysine in the feeding of broiler chickens and their particular importance in the vital activity of the bird's body. A description of the value and quality of the main types of compound feed for poultry, recipes of compound feed with different protein and lysine content for specific age groups of broiler chickens, and practical advice on the peculiarities of feeding and rearing of poultry are given. Current brief information on amino acid feed additives and general features of more rational and practical use of various protein feed of both vegetable and animal origin in poultry feeding of meat crosses – grains of cereal crops, processed products of oil crops – soy, sunflower, and many other components are provided. Theoretically and experimentally, the expediency of using different essential feed protein sources, differing in amino acid composition and bioavailability, in poultry feeding rations has been substantiated. In particular, the main principles of adequate feeding of broilers with compound feed with an increased level of crude protein of vegetable origin and a lower level of animal protein are described. Brief information on the effectiveness of safe levels of lysine of synthetic origin in the diet based on a variety of local feeds when growing broiler chickens in the conditions of a poultry farm in the western region are presented. It was established that compound feed with a significantly increased protein content of various origins – 24 %, 22 % and 20 % – positively affects broiler chickens' productivity. The highest level of productivity was noted for the lysine content in broilers' compound feed in the first growing period – 1,22 %, in the second – 1,14 % and in the third – 1,09 %. The high quality, nutritional value, and beneficial effects of amino acid premixes are directly influenced by the available feed raw materials, mainly of vegetable origin, used for the production of compound feed in the conditions of a broiler poultry farm, the uniformity of mixing with the appropriate quality feed and the optimal dosage of amino acids in each portion of the feed mixture.

The major cost of production in poultry farming is towards the feed cost. It shares around 80 per cent of total cost of production incurred during the poultry rearing. In order to reduce the cost of production, low cost feed formulation by using locally available feeds is the need of the hour. In this regard the present study was conducted to analyze the effect of feeding azolla on the performance of backyard poultry farming. For this one week old 30 chicks of Swarnadhara were selected for each group and 3 such groups were made. The first group (T1- control) was fed with the only recommended Desi starter feed (commercial feed), second group(T2) was fed with wet azolla by replacing 30% of desi starter and the third group(T3) was fed with the dry azolla by replacing 30% of the desi starter. After the 21 days feeding trial, it was found that the weight gain of second and third trial was at par with the control group indicating the azolla can be used as a partial substitute to the desi feed which is used by the farmers to feed the chicks at early stage. By this way the feeding cost can be reduced by 30 per cent, which directly will be added to the total profit gain.

It is necessary not only to increase the production of poultry products, but also to improve its quality while reducing the prime-cost. One of the solutions to this problem is the use of diff erent feed additives in poultry feeding, made from components of natural origin to meet the needs of poultry, which makes it possible to use for the production of compound feed. Recently, Russia has been paying more and more attention to such a sub-branch of poultry farming as quail farming. This is due to the fact that its products are in demand in the modern market, and production does not require large investments, which makes it possible to receive high incomes from the sale of both meat and eggs in the shortest possible time. The purpose of the research was to study the influence of compound feeds with beech fl our on the productivity of quails of the parent herd. The research was aimed at studying the egg productivity of quails. The results of a study on quails of the parent herd when using compound feeds with 1,0 % beech fl our have been presented in the article. Due to the better assimilation of feed nutrients, the introduction of beech fl our into the structure of the diet helped to increase egg productivity and reduced feed expenditures for products. Thus, when using the developed compound feeds, the average daily feed consumption decreased by 0,71 %. Data from the balance experiment showed that when using compound feed with 1,0 % beech fl our protein digestibility increased by 1,16 abs.%. It has been established that the use of compound feed with the introduction of 1,0 % beech fl our was of practical importance due to an increase in the productivity of quails and reduction in the prime-cost by 1,93 % for production of one hatchable egg.

Based on the results of the analysis of feed materials on the content of micronutrient elements and conducting scientific experiments on broilers chicken, the most effective source of Manganese, Zinc, Iron and Copper in mixed feeds, which contributes to solving the problem of increasing the quality of feeding and intensifying the growth of poultry has been substantiated. The optimum source of essential elements (Mn, Zn, Fe, Cu) for broilers chicken through feeds, the level of their incorporation into mixed fodders have been experimentally determined, and their influence on productivity and feed costs per 1 kg of body weight gain have been investigated. The tasks set in the work have been solved experimentally using analytical (analysis of literature sources), zoo-technical (growth indices, feed intake) and statistical (processing of the results obtained) methods of research. The use of mixed feeds in feeding broilers chicken which contained glycinate of Manganese, Zinc, Iron and Copper making 75 % of the needs, contributes to increasing their body weight by 2.5 % and increasing the growth rate by 2.4 %. Feed costs per 1 kg of broilers chicken growth were 1.5 % lower than the young bird index of the control group.

Full textAbstract:
A new phase system of feeding pheasants at their intensive rearing for meat, enhanced by factors of amino acid and energy influence on the young poultry growth rate into account its feeding preferences has been developed and allowing to obtain the live weight of pheasants at the age of 17 weeks at the level of 900 g and more. With the use of this system the yield of gutted carcass of pheasant reaches 60–61 % of the pre-slaughter weight with a sufficiently high specific weight of valuable parts-breast (40–42 %) and legs (29–30 %). In the proposed system of poultry feeding the same type of corn grain component of compound feed is more effective when it is 55 % by weight,. The experimental data confirm that the corn type of feeding pheasants intensively reared for meat, contributes to the activation of feeding behavior of young poultry. At the same time, the total time of feed consumption by poultry per head in comparison with the use of a set grain feeds (wheat – 15 %, barley – 11 %, corn – 31 %, peas – 8 % by weight) significantly increases by 12–13 minutes per day. The increase in feed activity is one of the factors allowing to increase the live weight at 17 weeks by 112,9 g or 14.5 % (P < 0,001) and the weight of pheasant legs after slaughter by 20,0 g or 14,7 % (P < 0,05). At the same time feed expenditures per 100 g of growth are reduced: dry matter by 0,12 kg (22,2 %), metabolic energy by 1,51 MJ or 20,8 %, and raw protein by 0,03 kg or 25 %. The preferential use of corn for fattening makes it possible to reduce the sale price of young poultry of meat purpose in live weight by 53–54 rubles or 15–16 %, and in the form of gutted carcass by 58–59 rubles or 9,5–10,0 %, which increases the effectiveness of pheasant meat production technology.

Animal origin protein sources and protein feeds at the base of soya and soya processing products are poultry diet important components. Protein products being received with usage of modern technologies of microbiological synthesis may be used as an alternative protein source. Positive results have been received in experiment with pharaon breed quails that were fed with these products instead of fish meal during all the raising period. Complete fish meal replacement with this protein has led to 42-day quails average body weight by 1.95% in comparison with control group. Male and female body weight has been more than in control group by 0.39 and 3.3% respectively and feed conversion has been better by 2.93%.

Full textAbstract:
For effective use of feed ingredients in diets for the various classes of animals, it is important that the feeding value of feed ingredients is properly estimated. This applies in particular to the useful or bio-available energy content, as feed energy generally represents the single largest cost-factor in animal production. In spite of their limitations, digestible energy (DE) and metabolizable energy (ME) systems are used widely in North America to estimate the useful or bio-available energy content of feeds and feed ingredients for pigs and poultry, largely because experimental procedures to establish DE and ME values are relatively simple. Some of the limitations of DE and ME systems can be overcome by using empirical net energy (NE) systems, whereby feed or feed ingredient NE content is predicted from digestible nutrient contents. However, empirical NE systems require estimates of the animal’s maintenance NE needs, which cannot be measured directly and have been estimated to vary between 489 and 750 kJ kg-1 BW0.60. Moreover, estimated feed or feed ingredient NE contents only apply to one particular animal state. The practical application of NE prediction equations requires an accurate characterization of nutrient contents and digestibility of feeds and feed ingredients. An accurate and flexible assessment of animal and feed effects on energy utilization requires the use of mathematical models in which transformations and use of dietary nutrients for different body functions are represented. Effective use of such nutrient flow models requires accurate characterization of feeds and feed ingredients and of animals in aspects of nutrient partitioning for the various body functions. This type of model can be used to predict accurately the useful energy supply from feeds and feed ingredients for specific animal states for diet formulation purposes. Nutrient utilization models may be refined to explore additional aspects of nutrient utilization, such as dynamics of nutrient absorption, the utilization of nutrients via alternative and competing metabolic pathways and inter-organ nutrient metabolism.

Recently, the composition of compound feeds used in poultry farming has changed significantly. But no matter how the set of ingredients in compound feeds is transformed, they should serve as sources of protein and energy. In recent years, original varieties of grain fodder crops have been obtained, which are characterized by increased energy and protein nutrition, such as hullless forms of barley, characterized by a reduced content of indigestible fiber, and therefore, have increased nutritional value for poultry. Therefore, the introduction of naked barley into the composition of feed for quails is of particular relevance. The article presents the results of a study on the use of the effect of compound feed with the introduction of 15 and 20% naked barley on the productivity of laying quails. When feeding quails with experimental mixed fodder, the average daily consumption of mixed fodder decreased by 1.75 and 2.53%, the intensity of egg production per average laying hen increased by 12.88 and 4.74%, and the cost of production of quail eggs decreased by 10.44 and 4.04%.

Poultry production in Malaysia is heavily dependent on imported feed ingredients. There is a need to utilize local feed ingredients such as palm kernel expeller (PKE) to sustain poultry industry through physical treatments and so that it suitable to be incorporated into the feeds. Hence this study evaluates on the effects of control (0% PKE), untreated PKE (UPKE) , extruded PKE (EPKE), less-shell PKE (LSPKE) and extruded less-shell PKE (ELSPKE) at 10%, 20% and 30% inclusion rates in finisher diets (d 21-42) showed that growth performance of broilers (Cobb 500) fed 10% PKE, 20% LSPKE and ELSPKE, were comparable to control birds. At 30% PKE inclusion, broilers performance was significantly (P<0.05) reduced. Birds fed PKE diets, irrespective of treatments and inclusion levels had lower LDL and total cholesterol, and similar villi height and crypt depth compared to control. At 30% PKE inclusion level, although energy metabolism was enhanced, as indicated by the up-regulation of hexokinase I and phosphofructokinase, but broilers growth performance did not improve. The feeding trial showed that broilers fed 25% or 30% LSPKE (grower feed, d 16-24), followed by 20% LSPKE (finisher feed, d 25-35) containing feed supplements 0.02% commercial enzymes and 0.30% humic acid), had comparable FI, BWG and FCR to broilers fed commercial feeds. Broilers fed 25% or 30% UPKE (grower feed, d 16-24) followed by 20% UPKE (finisher feed, d 25-35) showed significantly higher (P<0.05) FCR compared to birds fed commercial feeds. The cost of feeds for production of birds fed LSPKE feeds (2.27-2.29 RM/kg liveweight), was lower than those fed commercial feeds (2.36 RM/kg liveweight). The study showed that physical treatments enhanced the nutritive value of PKE and feeds containing 25-30% and 20% LSPKE as grower and finisher rations, respectively, could attain broilers growth performance comparable to broilers fed commercial feeds.

In the feeding of poultry, the search for new alternative feed sources and additives is promising. Such non-traditional feed sources are processed products from mustard and pumpkin seed oil. The purpose of the work was to study the use of non-traditional feeds, diff erent formulations of premixes and PVMC in the production of broiler meat. The studies were carried out on poultry crosses Kobb 500, HUBBARD ISA and Ross 308 under the conditions of the laboratory and clinical complex of the Volgograd State Agrarian University and poultry farms in the Volgograd region. (“Kumylzhenskaya”, AO “Poultry Farm Krasnodonskaya”). The introduction of Sarepta concentrate into the formula of compound feed for broiler chickens had a positive eff ect on the metabolic processes occurring in their body, as well as the positive eff ect on the growth of poultry and reduced feed intake. The use of Gorlinka concentrate instead of sunfl ower presscake in the intake of compound feed for broiler chickens led to the increase in the live weight of poultry and a signifi cant reduction in feed expenditures per 1 kg of live weight gain. The introduction of pumpkin seed presscake instead of sunfl ower in the feeding of broiler chickens contributed to the increase in the nutritional value of meat and improved taste qualities. The introduction of 1,5 %, 3,0 and 3,5 % of VolgaVit premixes into the broiler diet had the positive impact on the growth indicators and the quality of the resulting meat, which in turn aff ected economic effi ciency. The best result was shown by the 2nd experimental group of broilers, in which 3,0 % of the VolgaVit premix was introduced into the feed recipe. Studies on the use of non-traditional feed and diff erent formulations of premixes in the production of broiler meat have shown their positive eff ect on the growth rate of poultry of various crosses of poultry and meat quality indicators, which was also confi rmed by calculations of economic effi ciency and the results of production check.

The article analyses the issues of balanced feeding of broiler chickens and their balanced diet. The results of studies aimed to determine the effect of mixed feeds on the productivity of Arbor Acres cross broiler chickens and the economic efficiency of poultry meat production companies are presented. It was found that broilers from the experimental group, who were fed with improved compound feed with additional sources of proteins and carbohydrates and feed additives exceeded broilers from the control group by their live weight at all ages. At the slaughter age, the average weight was more than 39.2%. The experimental group consumed 10-15% less feed whose conversion was 2.4 and 1.9 kg in favour of the group feeding with the new compound feed. The new compound feed had a positive effect on the viability of broilers: there were no deaths during the period under study. According to the control slaughter results, it was found that the pre-slaughter live weight was higher by 35% in the experimental group. The weight of edible parts increased by 6%. The improved compound feed can be used both in industrial conditions and by poultry farms.

Based on marketing research, it has been proven that aquaculture is one of the fastest growing branches of food production in the world. The main method of increasing fish productivity in ponds is fish feeding, which is an objective reality with high intensification of fish farming. With the intensification of production processes, the role of feeding is constantly increasing, and the cost of feeding in the cost price of fish is about 40% and has an upward trend. In this connection, the problem of rational feed use becomes extremely important. It is justified that the use of high-quality feed and feed additives in the diet of fattening animals significantly increases the productivity and profitability of the operation of livestock, poultry, and fish farms. 160 factories are engaged in the compound feeds production in Ukraine, the production capacity of which is 7.5 million tons per year. The specified indicator should be realistically increased to 15 million tons of finished products per year. It is established that we will need to produce 60 percent more food by 2050 to feed the world's 9.3 billion people according to estimates compiled by the Food and Agriculture Organization (FAO). Therefore, animal protein production is expected to increase with this increase. According to IFIF estimates, the world production of compound feeds has reached more than 1 billion tons per year. Top 10 countries in world compound feed production in 2021–2022 are presented (according to Alltech Agri-Food Outlook 2023). The structure of compound feeds production by types of agricultural animals and poultry in the world in 2022 is summarized. It is proved that the production of fish compound feeds continues to grow in all the world regions. In the world (as well as in Ukraine), fishing and aquaculture play and will play a significant role in the coming centuries in ensuring the food security of the global population. It is necessary to make changes in policy, management, stimulate innovation and investment to the industry to ensure the food security of the planet through fisheries and aquaculture. It is established that the world volume of aquatic bioresources production is constantly growing and in 2022 reached the value of 176 million t/year. More than 150 million tons of aquatic biological resources were used for human consumption. In the conditions of the formation of market relations, against the background of significant costs for feed, feeding fish should be based on careful calculations, the logical conclusion of which should be economic expediency. On the basis of the marketing research of the situation on the market of feed supplements, a shortage of protein vitamin supplements and complete feeds for domestically produced fish was revealed. The restraining factors for the use of foreign supplements are their cost and interruptions in supply.

Micronutrients are an important component of a complete poultry feeding. Current detailed feeding standards provide guaranteed feed additives for farm poultry of the microelement complex. Among the normalized microelements there is no lithium, which according to the classification based on biological role for living organisms belongs to the group of conditionally essential elements. The purpose of the study was to investigate the effect of various doses of lithium in compound feed on the chemical composition and toxicological and biological parameters of caterpillar meat. The effect of additives of different doses of lithium (0.05 mg/kg, 0.10 and 0.15 mg/kg) in compound forages on the quality and safety of the products of slaughter of 70-day gosling was studied. The studies were conducted on gosling of the Legart breed. Feeding of gosling from day to 70 days of age was carried out by full-feed compound feeds. The birds of the experimental groups were additionally injected with lithium in the feed, mg/kg: the second group was 0.05; third – 0.10 and fourth – 0.15. The gosling of the control group did not receive lithium. Analysis of the results of the studies revealed differences between the control and experimental groups in the chemical composition of the muscular tissue of the gosling in favor of the latter. It was found that the introduction of lithium compound feed had a positive effect on the deposition of dry matter, protein and fat in the gosling of the experimental groups, which contributed to its increased energy and biological value. The best indicators of meat quality were in young animals, which during the growing period were fed compound feeds enriched with lithium at the rate of 0.1 and 0.15 mg/kg.

Abstract Dietary amino acids drive the performance and meat yield of modern broiler strains, and as such, amino acids are among the most economically important nutrients in poultry feeds. At the same time, minimizing N excretion is an increasingly prevalent sustainability target for poultry producers across the world, and this goal is often pursued by feeding reduced crude protein diets. Moreover, poultry production has largely transitioned away from the use of in-feed antibiotic growth promoters, bringing attention to the impact of dietary protein and amino acid levels on the intestinal and overall health of broilers. In response to these dynamic scenarios, research from our lab and others has attempted to more precisely link dietary supply of essential and non-essential amino acids with their functional needs for broilers subjected to various pathogenic and environmental stressors. This presentation will address existing research and knowledge gaps related to functional amino acids in the context of precision nutrition to enhance poultry performance and health.

Quality parameters of food eggs are influenced by paratypic factors and, firstly, by feeding factor. The issues of maintaining appropriate quality characteristics of eggs while improving poultry feeding programs seem to be relevant. In this regard, the aim of our study was to evaluate quality parameters of food eggs of Lohmann LSL Classic cross hens, depending on application time of three-phase compound feed in poultry feeding. The study was carried out at OOO Varaksino Poultry Farm, Zaviyalovsky District, Udmurt Republic. Three groups of laying hens were formed for the study, by the method of analogue groups, each of which consisted of 3 parts of birds. The groups differed by time of application of compound feed recipes of three phases. Morphological analysis of food eggs was carried out by instrumental method, the components were weighed on a VK-600 electronic scales. Biophysical parameters of the constituent components of the eggs were determined using a digital ovoscope DE 16000. The analysis of the qualitative characteristics of eggs at the age of 52 and 72 weeks did not reveal a significant difference between the groups in terms of morphological and biophysical parameters, except for yolk diameter at 52 weeks. The diameter of the egg yolk in the third group was significantly less (P ≥ 0.95) than the same value in the second group by 2.6%. Consequently, the factor of using different phase durations in feeding of laying hens did not have a significant effect on qualitative characteristics of food eggs. Obviously, final effectiveness of application of the studied feeding factor will depend on the level of egg production and the cost of feeds.

Due to the rapid growth of the population and the growing consumption of meat products, the issue of finding alternative sources of animal protein in feed production is more acute than ever. Insects are a promising protein component in feed production today. The article examines the state and prospects for the use of insects that have a high nutritional value, consume less resources and are environmentally friendly. The volumes of protein production obtained from fly larvae, flour worms and other insect species are given. The distribution of the use of insects for different types of animal husbandry, poultry farming and aquaculture in recent years is given. The main world leaders companies engaged in the cultivation of larvae and breeding of worms are presented. A comparative analysis of the content of crude protein and fat in various types of insects and traditional protein sources such as fish and soy meal is presented. A literature review of the results of the use of insects in the feeding of pigs and poultry by the world's leading scientists is presented. Insect-based animal feeds have been shown to have advantages over grain-based feeds. Test results are shown showing that crickets, black soldier flies and worms have the same protein digestibility as soy and provide more lipids, vitamins and minerals. The inclusion of insects in compound feed is one of the strategies for finding alternatives to create conditions for animal feeding that would be consistent with the concept of sustainable development. Data from a study on the effect of insects on egg production is also presented, which showed that yolk color, shell tear strength, and shell thickness were significantly increased by the addition of black soldier fly larvae. The results of studies on the use of insects in feeding fish are analyzed. The use of protein-chitin concentrate of Hermetia illucens larvae in feeding tilapia showed that it almost completely corresponds to fishmeal in terms of nutritional value.

The article is a summary of the literature on the main aspects of the modern bird feeding system. Theoretical aspects and results of experimental research of scientists on the substantiation of parameters of protein and amino acid nutrition are given, which is an important factor that, under appropriate conditions can significantly guarantee the realization of the genetic potential of corresponding breeds and crosses of poultry. It is shown that an important aspect of protein nutrition is the ratio of feed amino acids. Their negative interaction can be caused by a deficiency of one or more amino acids, an imbalance between them, antagonism, and toxicity. This is accompanied by effects on various physiological and biochemical processes, significantly affects appetite, intestinal absorption, renal reabsorption and transport of amino acids, their catabolism, rate of protein decomposition, synthesis, and formation of toxic metabolic products. The data show that the required level of energy for the bird's body is provided by carbohydrates (mainly of plant origin) and lipids (fat supplements of various origins). It is noted that lipids promote the absorption, transport, and deposition of fat-soluble vitamins. The effectiveness of using fat supplements as energy depends on their source. At the same time, among the indispensable nutrients that have a significant impact on growth intensity, reproductive quality, poultry productivity, and biological value of products, an important role is played by macro-and micronutrients. Many researchers emphasize that along with the use of traditional feeds in poultry feeding, the possibilities of non-traditional cereals rich in protein and lipids are not fully used. A limiting factor in their use is the presence in their composition of anti-nutrients contained in many feeds. Once in the digestive tract of animals, they negatively affect the absorption of feed nutrients. In most cases, the consumption of such feed by animals is manifested in growth retardation, increased feed consumption, hormonal effects, and, less frequently, in the dysfunction of certain organs.

Quail is one of the potential sources of animal protein from poultry as egg producers. An egg contains complete nutrients, namely protein, fat, vitamins, and minerals. As food, eggs must be maintained both physically and chemically to be safe for consumption. This study aimeds to examine the effect of selective feeding on the quality of quail eggs. This research was carried out at Percut Sei Tuan Subdistrict, Deli Serdang Regency, North Sumatra, which had been implemented from August to November in 2018. The study used a completely randomized design with 4 treatments and 5 plots. The study used egg samples from quail aged five (5) months. The treatment consists of Commercial feed (T0), 2 energy source feed (rice bran, corn) with 2 (T1), 3 (T2), 4 (T3) protein source feeds (fish meal, soybean meal, coconut meal, Poultry Meat Meal). The results showed that the treatment gave a significant effect (P<0.05) on egg weight, albumen, and eggshell weight, commercial feed showed eggs weight higher than free choice feeding treatments, while among free choice feeding treatment did not show significant effect. The free choice feeding treatment has a significant effect on the yolk weight, where T2 has the lowest yield. Percentage of yolk, albumen, quail eggshell and egg index, egg yolk index, albumen index, haugh unit and quail yolk color did not show significantly different (P>0.05) among treatment. It can be concluded that the commercial feed showed higher egg weight but had no significant effect (P>0.05) on the proportion of eggs and the interior quality of quail eggs, while among free choicee feeding treatment has no effect.

Full textAbstract:
This work is aimed at applying holonic control system to poultry house travelling hopper feeders with the comparative cost analysis. It adopts HCBA which is suitable for controlling the reconfigurable automated processes. The feeder consists of parts for different types of poultry feeds dispensable from the feed reservoirs and carried around by travelling hoppers along the feed carts. The simulations were carried out using MATLAB and SIMATIC software. The responses of the speed of each traveling hopper were determined to be 1.04 sec, 1.91 sec and 0.0841% for rise time, settling time and percentage overshoot respectively. The parameters of the embedded controller in STEP 7 CONT_C FB41 data block translate to a constant gain of 10, integral time constant of 100 ms and derivative time constant of 280 ms. Visual results from the HMI show the system’s ability for customization, cooperation and autonomy for implementation of any poultry feeding program. The cost analysis shows that it is profitable for farm capacity of 10,000 birds and above with low labour cost and average annual energy cost of about N708,000. The feed wastage loss is reduced by 66% while depreciation is 10% as compared to cage system with belted conveyor feeder.

A comprehensive and in-depth understanding of modern industrial poultry production technology is a vital condition for the development of poultry enterprises. Among the factors that determine poultry farming's development, the state and development of the feed base are of paramount importance. One of the promising directions for organizing rational poultry feeding based on self-produced feed is the use of new feed sources in compound feeds that have a multifaceted positive impact on poultry health. This study aimed to determine whether feeding feather meal induces changes in the body weight of laying hens, feed consumption, and egg production. The experiment was conducted on laying hens of the Hy-Line Brown W-36 breed without beak trimming, aged from 21 to 34 weeks at an industrial poultry farm. The chickens were placed in standard cages arranged in 6 tiers (with eight chickens per cage) and were distributed into five randomized groups. Four diets were formulated with the inclusion of feather-based feed additives in the base diet at levels of 2.0, 2.5, 3.0, or 3.5 kg per ton, while the control group was maintained on the standard diet. Research results using feather meal as part of the compound feed for laying hens have revealed that the inclusion of this additive had a positive impact on the live weight dynamics of Hy-Line Brown laying hens. Positive trends in absolute live weight gains were observed in the experimental groups compared to the control group, with EG1 showing an increase of 56.78 g (4.8%), EG2 with 43.66 g (3.7%), EG3 with 33.26 g (2.8%), and EG4 with 25.75 g (2.1%). The highest retention rate of laying hens was recorded in the first (EG 1) and second (EG 2) experimental groups: 98.9% and 97.9% respectively. The difference in retention between the first experimental group and the control group was 4.1%, while between the second experimental and control groups, it was 3.1%. The feather meal feed additive is an effective protein supplement, and research has revealed its positive influence on live weight gains and the survival of laying hens. The most effective level is 2 kg per ton of compound feed, which can be explained by the data observed in EG1.

Full textAbstract:
The future feeding of poultry is considered under two scenarios: one relating to developed regions where the feed supply is secure, and the other relating to some developing regions where it is less certain. No major changes are anticipated in regions with an ample supply of conventional feed ingredients, but significant changes are likely in regions which are attempting to expand their poultry industries with an inadequate indigenous supply of conventional feedstuffs. They will have to rely on strategies to improve protein utilization, such as supplementation with amino acids or the use of proteases, or strategies to improve energy utilization, such as the use of enzymes or unconventional feed sources. In developing countries, meanwhile, likely developments include the emergence of a feed manufacturing infrastructure to support the various sectors of the poultry industry and the more widespread adoption of integrated plant/poultry/soil production systems that emphasize economic efficiency and sustainability.

Full textAbstract:
This paper reviews the current state of bio-processing of market waste to poultry feed in Uganda. A focus was put on crop wastes since previous studies have indicated that, they contribute the biggest percentage (about 90%) of the total organic waste generated in markets. These wastes majorly comprise of fruits and vegetables like mangoes, pineapples, jackfruit, watermelon, cabbage among others. They are usually in form of residual stalks, leaves, peels, and damaged/rotten crops. Crop wastes are rich in various bioactive and nutraceutical compounds, like carotenoids, polyphenols and dietary fiber. The wastes are a major worthwhile raw material and present feasible solutions to the problems of poultry feed scarcity and high costs associated with the conventional feed stuffs. This transformation can be achieved by developing appropriate technologies for valorization of wastes by nutrient enrichment. In concern to this, solid state fermentation (SSF) and rearing insects and earthworm using crop wastes are the promising novel technologies. High value added products/feeds can be produced through microbial fermentation of crop wastes. Insect protein can also be produced to replace the expensive silver fish and soybean protein sources. The review indicated that, the technologies have not been fully cherished within the country’s poultry feed industry. All the attempts and work done are still under research and pilot scale level. However, the on-going endeavors are continued widely to better conversion technologies in order to produce products that are safe for poultry feeding. Lastly, the limitations and strategies for processing poultry feed from market waste are reviewed.

According to many scientists, the list of trace elements that are currently used in compound feeds for various types of poultry is clearly insufficient. In recent years, applied research has been conducted to determine the physiological needs of poultry for certain mineral elements that perform important biochemical functions in the body. This also applies to such biotic ultramicroelement as selenium. Scientific research of domestic and foreign scientists in the field of physiology, biochemistry, medicine and veterinary medicine has proved that selenium is a trace element with a fairly wide range of physiological and biochemical effects. When developing and theoretically justifying optimal norms for introducing selenium into poultry feed, it is necessary to evaluate not only its productive qualities, but also the blood picture. The question of the influence of selenium on changes in blood parameters in the poultry body is a great theoretical and practical significance because it allows us to expand our knowledge of its biological role and explain the data obtained in experiments. In scientific and economic experience has been studied the influence of additives of different doses of selenium in compound feed on the morphological and biochemical parameters of the goslings' blood raised for meat. During the experiment, feeding of goslings of all groups were carried out with dry feed mixes in accordance with existing norms. The goslings of the first control group did not receive selenium supplementation. The poultry of the second experimental group were additionally fed selenium at the rate of 0.2 mg/kg, the third of 0.3 and the fourth of 0.4 mg/kg. It is established that the additive in the feed of different doses of selenium stimulate hemocytopoiesis are added to different compound feeds, this is achieved by a homogeneous tendency per day, within physiological values in the goslings' peripheral blood number of red blood cells (by 1.7–3.9 %), white blood cells (by 2.1–3.2 %) and hemoglobin (by 2.4–8.6 %). Immune defense mechanisms are activated, which is manifested in an increase in the level of total protein (by 1.4–3.8 %) and the concentration of immunoglobulins in the blood serum (by 3.2–9.7 %). It is found changes in the content of total glutathione and its reduced form in the blood indicate a positive effect of selenium on the non-enzymatic element of the antioxidant defense system of the poultry's body. The addition of selenium to compound feed at a dose of 0.3 mg/kg had a significant effect on the morphological and biochemical parameters of the goslings' blood raised for meat.

In Russia, different quail breeds are widely grown and bred at specialized poultry farms and private farmsteads. In the Amur Region, only private farmsteads engage in this type of aviculture. The most common breeds are Pharaoh quail, Japanese quail, and Estonian quail. 100 eggs of the Estonian quail have been prepared for hatching in a specialized room at a private enterprise. The incubation has been carried out in the Rcom 20 MAX (RMX-20) machine at a temperature of + 37.2–380C and 55–60% humidity over 17–18 days. The egg hatchability amounted to 75%. In Russia, the birds receive balanced complete feeds of the following grades: P-K-5, P-K-2-1, P-K-6, Start, Super Start, RusQuail, Multigain and others. These feeds include different percentage mixtures of corn, oats, wheat, barley, meals and various types of flour (soy, fish, rice, etc.), yeast, chalk, phosphates, sodium chloride and other minerals. In the Amur Region, the balanced feed ration for poultry is produced by local companies “Amuragrocenter” and “Grinodir". These products have been used for feeding the chicks. The study of the Estonian quail bred at a private farmstead using the Amur feeds revealed some changes. According to the literary sources, the average weight of the Estonian breed is 180–200 g. The weight of the quails grown under the specified conditions was significantly higher — up to 200–260 g. In many regions, consumers prefer local products that they trust.

Abstract Maintaining a healthy gastrointestinal tract (GIT) is critical for better nutrient utilization, optimum performance, and overall health of poultry. Thus, several nutritional strategies have been tried to improve poultry’s gut health. More recently, different nutrients and feed additives are being used in poultry diets with some success when antibiotic growth promoters (AGP) are not an acceptable option anymore. However, effective modulation of gut health depends on the methods and timing of the compound being available to host animals. Routinely, the alternatives to AGP like prebiotics, probiotics, symbiotic, enzymes, and other nutrients are provided in feed or water to poultry. However, the GIT of the newly hatched poultry is functionally immature, despite going through significant morphological, cellular, and molecular changes toward the end of incubation. Thus, the early growth and development of GIT are of critical importance to enhance nutrients utilization and optimize the growth performance of poultry. Maternal nutrition and in ovo feeding have been used and found to be effective in improving gut health but with inconsistent results. The effects of maternal nutrition on the development and viability of embryo and post-hatch growth performance of birds are documented. However, there is limited information on how maternal nutrition affects the gut health of chicks. In contrast, information on the same from in ovo feeding of nutrients and feed additives has increased in recent years. The results show that in ovo feeding can be a good tool to modulate gut health of post-hatch birds positively. However, more information is needed on the proper route and time of inoculation, optimum doses, and effective combination of different compounds to maximize the benefits of in ovo feeding technique in poultry production.

The article presents the data on the use of higher aquatic vegetation (HAV), such as naiads, as an alternative source of plant proteins in poultry feeding. The use of non-traditional raw materials contributes to the development of immunity in poultry without the need for antibiotics, which is relevant in the context of combating antibiotic resistance. The developed feed composition can not only significantly improve the quality of poultry feed, but also provide consumers with high quality and safe products. The results of the research can be promising for poultry feeding practice and contribute to the sustainable development of poultry farming.
