The article provides experimental data on the study of application of two probiotic additives - “Sitexflor - 1” and “SGOL-1-40”, included at different dosages in the diets for young pigs, on usage of the supplied nitrogen and their productivity. Such parameters were taken into account when forming the groups as: weaning time (60 and 45 days), preliminary feeding the mothers with the probiotic supplements under study during the suckling period. The results, characterizing the piglet productivity in case of application of “Sitexflor - 1”, convince that the most effective dose is 30 mg per head per day, which provided an average daily gain of 351 g, which is 7.3% more than the control, primarily due to greater nitrogen retention in the body (by 9.91%), but with lower consumption of energy feed units per 1 kg of gain -4.43 (by 11.4%). The results, characterizing the piglet productivity when applying “SGOL -1-40”, reliably confirm its most effective dosage of 2.5% of the dry matter of the diet, which provided an average daily gain of 404 g, which is 15% more than the control, due to greater nitrogen retention in their body (by 4%). Introduction of “SGOL -1-40” in the diet provided a significant reduction in the cost of energy feed units per 1 kg of gain in comparison with the control by 14.3%. The nitrogen balance in the body of young pigs was positive in both experiments, but the amount of nitrogen retained in the body was different. At the same time, even a greater amount of deposited nitrogen in animals in the first experiment did not allow to achieve the expected live weight increase, and in the second experiment, on the contrary, even surpassed it. Such data indicate that the supplied nitrogen with a diet enriched with a probiotic supplement was more effectively used in the body, exceeding the physiological level of its transformation into products.

Mycotoxins have been formed in feed are secondary metabolites of fungi and are quite stable substances that have teratogenic, mutagenic and carcinogenic effects. An effective way to combat mycotoxins in feed is the use of feed additives that adsorb toxins, prevent their absorption in the gastrointestinal tract of the animal and are excreted from the body. The infl uence of coconut enterosorbent Shelltic Es on fattening and meat qualities of young pigs has been studied. It has been found in the process of fattening that the highest feed digestibility was in pigs of the experimental group, in the diet of which enterosorbent has been added. The results of studies of the chemical composition and technological properties of pork have been provided. The positive eff ect of enterosorbent on precocity, absolute average daily gain of live weight and reduction of feed expenditures per 1 kg of gain has been revealed. In pigs from the experimental group the average thickness of the fat was higher and the area of the “muscle eye” was lower compared with animals of the control group, which indicates that higher rates of carcass yield have been obtained due to faster accumulation of fat tissue. The weight of internal organs of pigs indicates the intensity of metabolic processes in the body. In experimental animals the weight of the lungs was 0,1 kg lower, and the liver and heart were higher by 0,13 and 0,01 kg, respectively. Enterosorbent had no effect on the content of vitamins in the liver of pigs of the compared groups. The content of impurities of organochlorine toxicants and toxic elements in the meat and liver of animals of the experimental group was lower than that of control analogues. Therefore, the use of enterosorbent Shelltic Es promotes more active excretion of them from the body.

The purpose of the work was a comprehensive evaluation of the productive and reproductive traits of sows of Yorkshire and Landrace breeds and their offspring under the conditions of a breeding enterprise in the Republic of Belarus. During the studies of reproductive traits, it has been revealed that the highest rate of prolificacy among the evaluated breeds was distinguished by Yorkshire sows 14,0 heads for farrowing. In terms of milk content, Landrace sows were 2,5 kg or 4,57 % higher than Yorkshire sows. In terms of weight and socket weight per piglet at weaning at the age of 28 days sows Landrace piglets surpassed herdmates Yorkshire breed in the weight of the litter by 6,8 %, and the weight of one pig by 0,9 %. It has been found by the results of the evaluation of fattening and meat qualities of purebred young pigs that the best parameters were different gilts of Landrace breeds, whose age achieve the live weight of 100 kg was 163,1 days, and average daily gain of live weight – 864,8 g, which was higher than in young pigs of Yorkshire breed by 1,8 day or 1,09 %, and 28,9 g or by 3,46 %. The young pigs of Landrace breed has been characterized by the best values of the area of the “eye of loin” – 73,8 cm² and the highest yield and amount of meat – 68,5 % and 24 kg, which was 11,4 cm² or 18,2 % and 0,4 kg or 3,5 abs.%, respectively, higher than the herdmates of Yorkshire breed. The results obtained indicate the possibility of using boars and sows of Landrace and Yorkshire breeds not only in breeding, but also in industrial pig breeding.

In dairy cattle breeding, selection and breeding work is widely used in order to transfer the pedigree qualities of parents to the offspring and obtain highly productive young animals. In this regard, in the conditions of «Enbek» LLP in the Akmola region, the growth and development of young Simmental breed depending on the origin was studied. Live weight of Litera line young animals at birth was 33.4 kg, at the age of 6 months-174.9, 12 months-251.8, 18 months-387.1 kg, respectively, Wildfang bull 32.0 kg, 165.5 kg, 251.3 kg, 378.6 kg. The average daily gain between the ages of birth and 6 months was increased. With age, the body parameters, height at the withers, increased from 104.3 cm and 103.5 cm to 125.4 cm and 123.9 cm, respectively, from 6 months to 18 months of young animals. According to the physique indices, we can say that the young Simmental breed is balanced. Only some deviations of the leggy index are observed from the optimal indicators. The index of legginess decreases with age by 7.7%, with indicators of 6 months – by 57%, at the age of 18 months-by 49.3%. The extension index for the period from 6 to 18 months increased by 10.5%, respectively, for 6 months-by 103.3%, for 18 months-by 113.8%. With age and an increase in live weight, the body of young animals lengthens, its width increases, the animal becomes deeper and relatively long-legged. Depending on the origin, we suggest using the Litera bull line, taking into account the growth and development of young animals, and the productivity indicators of bulls.

Статья отражает исследования по применению свежей пивной дробины в кормлении бычков на заключительном этапе откорма и сухой пивной дробины при выращивании ремонтных телок в возрасте 6-12 месяцев, которые показали ее положительное влияние на качество кормовых рационов и продуктивность животных. В основном рационе контрольных групп часть комбикорма заменяли пивной дробиной: при откорме бычков – 5 кг свежей дробины взамен 1 кг комбикорма, при выращивании телок – 0,5 кг сухой дробины взамен аналогичного количества комбикорма. За счет применения пивной дробины была повышена протеиновая ценность рационов и оптимизирован их микроминеральный состав, что способствовало активизации обмена веществ в организме животных и повышению их продуктивности. У бычков опытной группы живая масса в конце откорма и среднесуточный прирост были, соответственно, выше на 2,5 % и 7,4 %, нежели у контрольных животных. Данные показатели у телочек опытной группы были выше контрольных значений на 4,1 и 6,5 % соответственно. Затраты энергетических кормовых единиц на 1 кг прироста живой массы у животных опытных групп были ниже на 7,3-7,6 % в сравнении с контролем. Установлена экономическая целесообразность применения свежей и сухой пивной дробины в рационах молодняка крупного рогатого скота, так как за счет повышения интенсивности роста животных и значительной экономии зерновых кормов себестоимость 1 кг прироста живой массы, полученного на рационах с дробиной, была ниже на 6,2 % у телочек и на 10,4 % у бычков. The article reflects studies on the use of fresh spent grain when feeding bulls at the final stage of fattening and dry spent grain when growing replacement heifers aged 6-12 months, which showed its positive effect on the quality of feed rations and animal productivity. Part of the mixed fodder in the main diet of the control groups was replaced with spent grain. Bull calves got 5 kg of fresh spent grain instead of 1 kg of the mixed fodder and heifers got 0.5 kg of dry spent grain instead of the same amount of the mixed fodder. Thanks to pent grain, the protein value of diets was increased and their micro mineral composition was optimized, which contributed to the activation of metabolism in animals and increased their productivity. The live weight of the bulls of the experimental group at the end of the fattening was 2.5% higher than that in the control animals and the average daily gain was 7.4% higher. These indicators in the heifers of the experimental group were higher than the control values by 4.1% and 6.5%, respectively. The cost of energy feed units per 1 kg of increase in live weight in animals of the experimental groups was lower by 7.3-7.6%, compared with the control. The economic feasibility of using fresh and dry spent grain in the diets of young cattle was established, since due to an increase in the growth rate of animals and significant savings in grain feed, the cost of 1 kg of live weight gain obtained from rations with spent grain was 6.2% lower in heifers and 10.4% in bulls.

The purpose of the researches was to study the influence of different doses of smectic kizelgur and calf skim milk replacer in the recipes of compound feed for young pigs under the conditions of industrial pork production technology. The experimental part of the work has been performed under the conditions of the pig complex of LLC “BMPK” in the Karachevsky area in the Bryansk region. The research materials were compound feed for young pigs on fattening in the inclusion of different doses of smectic kizelgur. The infl uence of feeding compound feed with different doses of smectic kizelgur and calf skim milk replacer to young pigs on productivity, digestibility of nutrients and use of nitrogen, morphological and biochemical parameters of blood, fattening and meat traits of young pigs has been studied. Effective recipes for feeding compound feeds to young pigs prepared with the inclusion of different doses of smectic kizelgur and calf skim milk replacer have been identified. The data have been obtained from the first experiment of young pigs when them fed compound feed with different doses of smectic kizelgur; it has been followed that at the end of fattening the biggest live weight of gilts had in the 4th experimental group fed compound feed, which included 3 % smectic kizelgur. The influence of the additive on changes in live weight and daily gains when adding smectic kizelgur to compound feed in doses of 1,5 and 2,0 % was less, but the trend to increase these indicators over the period of fattening has remained. In the second experiment young pigs have been fed by compound feed, which included different doses of smectic kizelgur and calf skim milk replacer the average daily gain in live weight was higher in the 3rd experimental group, where they fed compound feed with the addition of 2,5 % smectic kizelgur and 2,5 % calf skim milk replacer by 2,2 %, than in the control group. The highest efficiency has been also obtained in the 3rd experimental group, where the monetary revenue has been received by 2160 rubles more in comparison with the control group of pigs.

For the first time, the rationale of using polystim in the technology of calf rearing in private subsidiary plots, on small and medium farms has been scientifically substantiated and experimentally proved to activate the protective and adaptive functions of the body to the keeping conditions and to more fully realize the biological potential of resistance and productivity. Thus, live weight, average daily gain and growth rate of young cattle of the experimental group were higher by the end of the observation period (180 days) than in the control group: in the conditions of personal subsidiary plots by 6.6 kg, 33.3 g and 0.28, on small farms - by 5.2 kg, 20.0 g and 0.08, and with the technology of keeping on a medium farm - by 4.8 kg, 13.3 g and 0.23 (P<0.05 ) respectively. The dynamics of exterior measurements of animals of all groups were similar to the nature of changes in their live weight and their average daily gain. At the same time, the incidence of respiratory organs diseases and the gastrointestinal tract in newborn calves was reduced to 25-40%, the duration of the disease was reduced by 2.45; 1.31 and 1.93 days (P<0.05-0.001).

Abstract. The availability and use of feed that enters the body of pigs depends on the amount and ratio of nutrients in it. Purpose. To determine the effect of different ratios of structural carbohydrates on pig productivity and digestibility of essential nutrients. Methods. Balance experiments were performed on pigs using the diets with nutrients level that corresponded to the need and the norm, and almost the same content of fiber, which differed in structural composition. Indicators of the content of basic nutrients, crude, neutral-detergent and acid-detergent fiber, as well as the ratio of hemicellulose, cellulose and lignin in it were taken into account. The indicators were determined according to the methods of zootechnical analysis. Results. The chemical composition of various bran, hay flour and prepared rations has been studied. It has been confirmed that the lignin content is the lowest in the corn bran and the highest in the barley one, with the highest amount of hemicellulose, a structural carbohydrate that is best broken down by enzymes. The composition of their carbohydrate-lignin complexes and the ratio of their structural carbohydrates have been studied. It was found that the productivity of pigs using fiber in their diet, which is characterized by 12% higher hemicellulose content and 31% lower lignin one, is 46% more than in the control group. It is proved that the introduction of wheat and barley bran, hay flour in the diets of fattening pigs weighing more than 75 kg is economically feasible, given the structural composition of fiber. The average daily gain will be 672 g with the inclusion in the diet of a mineral supplement that will provide the body of animals with all the necessary nutrients. Conclusions. The productivity of pigs largely depends on the content and composition of fiber in their diet. In the period when the live weight of fattening pigs reaches 75 kg, and by the end of fattening (120-130 kg), it is economically feasible to introduce bran into the diet, which implies mandatory control of the content and composition of fiber.

<p>The productivity of young meat quails was estimated at use of feed with different levels of arginine. Experimental studies were conducted in course of Problem Research Laboratory of feed additives of National University of Life and Environmental Sciences of Ukraine. Pharaoh quails were used for scientific experiment that was carried out by method of analog groups. Arginine level contamination in the diets of experimental groups was regulated by the introduction of feed synthetic analogs of amino acid. Part of arginine in mixed fodder of poultry control group was 1.57 % in the fodder of quails of 2-nd, 3-rd, 4-th and 5-th research groups and that were 1.39, 1.48, 1.66, 1.75 % respectively. The feeding of the was done by group and feed was distributed twice – in morning and evening. Ii was proved that the feeding of quails by mix fodder with arginine content of 1.66% contributes to increment of the live weight by 2.6 % on average, daily gain - by 2.7 %, the weight before slaughter by 3 % and reduce the cost of feed per 1 kg of growth by 1.5 %. This could contribute to the further research of arginine-lysine optimal ratio in mixed fodder for quails and their impact on zootechnical indices.</p>

In a study that lasted for 120 days, 20 weaned Yankasa ram lambs aged 6 months and weighing between 10.5 and 14.5kg with an average of 12.75kg were offered a basal Digitaria smutsii hay diet at 2% of body weight. This was supplemented with a concentrate mixture made to supply 14.6% crude protein and 2.6 Mcal ME per kg and offered to treatment groups A, B, C and D at 1, 2, 3, and 4% of body weight respectively. There were five replicates and the animals were fed individually. Results indicated that the differences in Average Daily Gain was significant (P<0.05) between all the treatments; the value increased with increased level of feeding. The cost of effecting one unit of live weight increase was not significantly different (P<0.05) between treatments, A, B, and C, but it was significantly lower (P<0.05) than for treatment D. The low growth response of lambs fed the concentrate at 1% of body weight and the higher cost per unit gain of lambs offered the supplement at 4% of body weight suggested that concentrate supplementation at 2 and 3% of body weight was adequate for optimum liveweight gains in the Yankasa sheep breed.
