The effectiveness of the biogenic stimulants action based on the larvae of the SITR bees drone brood and adult individuals of the ST drones on the chemical composition, physical and chemical, commodity technological properties, nutritional and biological value of the muscle and fatty tissues in young turkeys is studied. The turkey-poults of the 1st group received injections of a physiological salt solution, and the 2nd and 3rd experimental groups, respectively, of the SITR and ST biological stimulants, three times at the age of 1, 7 and 14 days at a dose of 0.1 ml per 50 g of live weight. It was established that in the middle sample of the muscle tissue in turkeys of the 2nd and 3rd experimental groups there were less water and more dry matter and protein. Biogenic stimulants contributed to the synthesis of muscle tissue in turkeys of the 2nd and 3rd experimental groups, in which contained 1.79 (B>0.999) and 1.31 (B>0.99) absolute % more protein and 0.32 and 0.23 absolute % less fat than in the control group. In the muscle tissue of turkeys stimulated with biogenic preparations, there were more tryptophan by 1.63 and 0.84 mg% and by 0.92 and 0.54 mg% less hydroxyproline than in turkeys at the same age of the control group. The protein-quality index of muscle tissue was higher in turkeys of the 2nd and 3rd experimental groups by 3.08 and 1.72% than in the control. The first place in the overall assessment of meat and broth quality was taken by the turkeys from the 2nd experimental group; the second place was taken by the turkeys of the third experimental group. Their superiority over the control group was 0.151 and 0.109 points, respectively. The fatty tissue of turkeys in all experimental groups has good quality and high digestibility indices. It has in its composition a large amount of polyunsaturated fatty acids; this indicates its high biological value.

The purpose of the work was to increase the effectiveness of rearing of young animals and milk production by providing dairy cows with easily digestible sugars obtained from local grain raw materials. The research on the use of grain molasses produced from rye grain in a pilot unit in the Sharkansky RTP UZHK-1000 in feeding cattle of Kholmogorskaya breed under the environments of the Udmurt Republic has been carried out. The innovative small-sized treacle unit operating on the basis of the principle of cavitation technology is designed for the enzymatic cleavage of grain polysaccharides to a more accessible form of sugars for assimilation. It has been revealed that the feeding of grain molasses to young cattle in the amount of 3 kg/head/day had a positive effect on the increase in the average daily gain of live weight and the intensity of growth of animals. In the first-calf heifers in control group the age of achieving the first insemination was 14,7 months with the live weight of 374,6 kg, in the first-calf heifers in experimental group it was 13,8 months, while their live weight was 378,2 kg. The insemination index in the first-calfheifers of the control group was satisfactory and amounted to 2,0, and in the cows of the experimental group it was good – 1,6 (P ≥ 0,95). The maximum milk productivity of first-calf heifers for 305 days of lactation has been recorded in the cows of the experimental group, where grain molasses was used, and amounted to 7702,0 kg, which was more than in the control group by 157 kg or 2,1% (P ≥ 0,95). Milk from cows of the experimental group was the most suitable for the production of fermented milk products. The physical and chemical parameters of milk were also higher in the group in which grain molasses has been fed. The lowest consumption of milk for the production of 1 kg of cottage cheese was noted in the experimental group of cows 6,43 kg, the same trend has been observed in the production of cheese where the consumption was 8,7 kg.

The effect of gonadoectomy (removal of the testicles) in Adler's silver roosters on the clinical condition, live weight, slaughter rates and chemical composition of the pectoral muscle was studied. The experiment was performed on 40 roosters of 6-weeks, which according to the principle of analogues were divided into two groups: control and experimental 20 heads each. It was found that in the preparatory period, which lasted 10 days indicators of the clinical condition – body temperature, pulse and respiration, as well as live weight of the roosters of the experimental group did not differ from the control. Gonadoectomy of roosters of the experimental group, conducted at the age of 45 days by a specially developed method, increased the body temperature of the poultry on the second day after surgical intervention by 1.03°C, and on the third – by 1.15°, while other indicators of clinical condition – pulse, number respiratory movements and live weight did not change compared to control. The duration of the postoperative period in the roosters of the experimental group was 3-4 days and ended with the healing of the wound on the skin. Subsequently, body temperature, pulse and the number of respiratory movements in gonadoectomized roosters corresponded to similar indicators of poultry in the control group. The live weight of gonadoectomized roosters in the rearing process, which was monitored decadelly from the 65th to the 95th day compared to the control did not change, on 105th and 115th day had a tendency to increase, and 125th day increased by 4.8 %. Slaughter rates of gonadoectomized roosters corresponded to similar indicators of poultry of the control group. The weight of the gutted carcass was higher by 5.2% and that of the muscular stomach by 7.8%. Differences in the chemical composition of the pectoral muscle of gonadoectomized roosters compared with control, namely: on the content of dry matter, moisture, fat, protein and ash were not found. Thus, gonadoectomy of roosters of the Adler's silver meat-egg breed does not affect their clinical condition, the chemical composition of the pectoral muscles, but increases the live weight of the bird on the 125th day of rearing

The animal husbandry cannot develop successfully without complete balanced feed and optimal forage supply. This article deals with the chemical composition of chlorella suspension. The ration is balanced with seaweeds as well as premixes, vitamins and bio supplement for the last decades. These seaweeds include chlorella - a representative of green microscopic algae. The use of chlorella allows for multi-factor balancing of the diet in accordance with modern feeding standards, which increases the productive effect of feed and significantly increases the transformation of nutrients into livestock products. This is arelevant issue of modern animal husbandry. The chlorella suspension was material for scientific research. It was made on the farm “In Samvel”, Ovidiopol District. According to the result of researches that took place on the farm " In Samvel", Biliayevka District, Odessa Oblast and SERF "Yuzhnyi" OSAGES NAAS, new data concerning chemical composition, the positive influence of investigated chlorella suspension on the growth and development of finishing pigs as well as feed costs by 1 kg of growth were obtained. It has been established that the chemical composition of chlorella suspension takes a special place among all feed additives used in farm animals feeding. It has been established that the additional use of chlorella suspension in the ration of finishing pigs of Large White breeds contribute to the increase of average daily gains by 121.9% against the control group in which chlorella suspensions was not given. Feed conversion to obtain1 kg of pigs live weight gain in the control group was 5.1 kg, in the experimental group - 4.2 kg and feed conversion index in the experimental group was higher by 21.4%. Thus the results of researches indicate the positive effect of investigated chlorella suspension on the growth anddevelopment of finishing pigs. Due to the obtained results, we can state that the chemical composition of the suspension chlorella takes a special place among all feed additives used in farm animals feeding. Chlorella has higher indicators of chemical composition, the amount of protein, vitamins and minerals in comparison with plant fodder and crops of agricultural production.

The production of ecologically clean fish products is in demand in the food market. As a result of the research, the nutritional quality and chemical composition of the muscle tissue of the Nile tilapia (Oreochromis niloticus L.) were evaluated using the pro-biotic additive Enzimsporin. A valuable quality of Nile tilapia meat is its high protein content. In the muscle tissue, the maximum amount of protein was 80.4%, in the yearlings of the 1st experimental group, which is 7.51% (P ≥ 0.99) higher than in the control group. Yearlings of the 2nd experimental group outperformed their peers from the control group by 4.8% (P ≥ 0.95). Its amount in fry of Nile tilapia varied from 72.27–72.73% in the experimental groups to 74.71% in the control group. The fat content in fry varied from 9.55% in the control to 12.19% in the fish of the 2nd experimental group. The amount of lipids was the highest in the control variant of Nile tilapia yearlings (11.48%), which is 6.48% more than in the 1st experimental group and by 4.48% more than that in the 2nd experimental group. The lipid-protein coefficient (0.06-0.09) of the experimental groups characterizes the meat as less tender, but high in protein, possessing lipotropic properties that protect the liver from fatty infiltration. The study of nutritional value and functional and technological properties shows that tilapia meat can be attributed to highly saturated food raw materials and used to obtain dietary products.

This article presents material on the study of the efficiency of raising Edilbayev sheep using a new feed supplement and assesses its effect on increasing the meat productivity of animals and improving mutton indices. To do this, we at Volgograd-Edilbay SGC LLC selected 30 animals of the Edilbayev breed of 7 months of age in two experimental groups according to the principle of pair-analogues with 15 animals each. The rams who received the standard diet were included in the control group, and their analogues, which were introduced a new feed additive in the diet, were included in the experimental group. The duration of the experiment was 105 days. In this case, the preparatory period of the experiment is 10 days, the transitional period is 5 days, the main one is 90 days. As a result of the experiment, it was found that at the end of the experiment, the rams of the experimental group exceeded their counterparts in the control group in live weight by 2.9 kg, or 5.72% (P≥0.999). As a result of the control slaughter, it was established that by the pre-slaughter mass, the rams of the experimental group are 1.65 kg or 3.35% more than analogues of the control group (P≥0.95); weight of fat tail fat - by 0.35 kg, or 13.21%; slaughter mass - by 1.49 kg, or 5.23% (P≥0.99); slaughter yield - by 1.09%, respectively. A study of the chemical composition of lamb showed that in the content of the rams of the experimental group in the meat, iodine was 0.08 μg / g more than the analogues of the control group (P≥0.95); silicon - at 3.92 μg / g; selenium - at 0.12 μg / g (P≥0.99); zinc - at 6.0 μg / g, respectively. According to the content of fatty acids, tail fat obtained from animals of the control and experimental groups differs in favor of the experimental group. Saturated fatty acids in turkey fat of animals from the experimental group contain 61.34%, which is 3.22% higher in comparison with the control group. Unsaturated fatty acids in animals of the experimental group contain 38.66%, which is 3.17% less in comparison with the control group. Thus, the highest results in meat productivity, chemical composition, and the amount of saturated and unsaturated acids were obtained from edilbaevsky rams that received a new feed supplement.

The results of the study of the effectiveness of new probiotic preparations based on strains of probiotic microorganisms in the preparation of silage from cereal-legume mixtures of annual forage crops with high humidity and their impact on the interior performance and productivity of fattening calves. in production conditions, two variants of vetch-oat silage were preserved, the control one was fermented with BPS-L leaven at a dose of 10 ml per tone, and the experimental one was preserved with probiotic preparation KT-L 18/1 at a dose of 8 ml per tone of green mass. Both preparations are domestically produced, created in the laboratory of probiotics of the Institute of Agriculture Microbiology and Agro-Industrial Manufacture of NAAS. A study of the chemical composition and nutritional value of silos showed that the addition of probiotic preparations BPS-L and KT-L 18/1 to the green mass by ensiling annual forage crops with high humidity (78-80%) contributes to the preservation of dry matter at 91-94, crude protein 90-93 and carotene 85-88%, provides the optimal level of lactic acid fermentation, accumulation of lactic acid at the level of 67-69%, acetic - 29-32% without accumulation butyric acid. Based on data on chemical composition, fermentation acid content and organoleptic evaluation, such silos were classified as quality class 1. Studies on animals (calves for fattening) lasted 140 days in the experimental farm "Obroshyne" Pustomyty district of Lviv region. The main diet of both groups consisted of cereal-legume hay, winter wheat straw, pulp and feed. Animals of the control group received an additional 15 kg of silage prepared with BPS-L, and experimental - 14.5 kg of silage with the KT-L 18/1. In the rumen fluid calves were fed silage harvested with drug KT-L 18/1 noted the increase in the concentration of nitrogen free amino acids and protein nitrogen in the background reduction of ammonia. Established tendency to increase the level of red blood cells and hemoglobin content of calves in the experimental group. Analysis of serum protein spectrum showed a significant increase in the level of albumin and γ-globulin fractions in animals that consumed silage prepared with the KT-L 18/1. Average daily live weight increase of calves in experimental group were 703 g, its 4.2% higher than in controls (675 g).

Summary. The disbalanced feeding and the uneven distribution of micro- and macroelements in the environment leads to a trace element, in particular hypomelanosis. To accelerate the growth and preservation of young farm animals include in the diet of various biological additives and drugs, which include selenium. For stimulation of weight gain in the livestock industry, as well as for the prevention and treatment of pathological processes in addition to micro - and macrouse amino acids, primarily methionine. The aim of this work was to study the influence of composition of DAFS-25+Polizon on morpho-biochemical parameters of blood and functional state of the liver in fattening bulls of black-motley breed in the conditions of the Republic of Bashkortostan. Experiments using were conducted on bull-calves of black-motley breed of the properties in the properties age from 6 to 15 months. The first experimental group during the experiment was additionally given the composition of DAFS-25+Polizon at a dose of 2 mg/kg, the animals of the control group received a standard diet. To assess the impact of the composition DAFS-25+Polizon on metabolism cattle studied morphological and biochemical indicators of blood and conducted histological examination of the liver. It is established that the use of the composition of DAFS-25+Polizon at a dose of 2 mg/kg increases the number of erythrocytes and hemoglobin in the experimental group and reduces the amount of white blood cells. The serum content of total protein, phosphorus and calcium increases in the group of experimental animals. Microscopic examination of the liver revealed no changes in the structure of the organ and hepatocytes in the experimental group, whereas in the control group hemodynamic disorders and dystrophic changes in liver cells were observed. Thus, the use of the composition DAFS-25+Polizon at a dose of 2 mg/kg of live weight in fattening bulls black-and-white breed contributes to the increase of redox processes in the body, stimulation of metabolism, prevent the development of liver disorders of cellular mechanisms of metabolism, optimizes the structure of the liver, which generally provides higher productivity.

Mineral Feed Additives

Animals imported to Yakutia from other regions fall into feeding and housing conditions that differ from their usual agro-climatic conditions, which causes the problem of their adaptation. Yakutia is one of the areas where the feed of its own production has a lack of basic minerals, which affects the health and productivity of animals, which has an additional negative influence on the adaptation process of imported cattle. In order to replenish macro- and microelements in the body, it is necessary to introduce various local mineral feed additives, premixes, and use mineral salts into the ration. Under the conditions of Central Yakutia the influence of local mineral feed additives (zeolite of the Khonguruu Deposit in the Suntar district and sapropels of local lakes) containing macro- and microelements that increase the meat productivity of steers has been studied. As a result of the research the influence of local mineral feed additives on meat productivity and physiological condition of Hereford steers has been established. Influence of zeolite and sapropel in a complex with mineral salts on digestibility of nutrients of the ration and use of nitrogen, calcium and phosphorus by experimental animals has been defined. The influence of feed additives on the quality of meat products has been studied. The results have shown that the use of local mineral feed additives in the composition of ration of steers during the fattening period at a dose of 0,7 g zeolite per 1 kg of live weight of the animal and 200 g of sapropel in combination with 10 g of mineral salts contributed to the gain in live weight, carcass weight, carcass yield, yield of edible parts, and economic efficiency of fattening. For the entire period of the experiment the gain in live weight in groups was: in control group 2222,9 kg, in the 1st experimental group 2396,2 kg, in the 2nd experimental group 2471,1 kg. The total economic effect for the 1st experimental group for the period of experiment amounted to 44,3 thousand Rubles, for the 2nd experimental group 78,0 thousand Rubles or per 1 head/day 14,06 and 24,76 Rubles, respectively.
