The results of the influence of the complete feeding on the formation of productive and conformation traits of Simmental×Holstein heifers with high blood content (87,5 %) of Holstein breed have been presented in the article. The heifers of the control group have received a farm ration compiled according to detailed standards, and their analogues from the experimental groups have received by 5, 10, 15, 20 % higher. During the entire growing period, the heifers of the 1st experimental group have been consumed 3325 EFU and 362,5 kg of digestible protein, the 2nd group – 3187 and 348,6, the 3rd – 3049 and 334,7, the 4th – 2994 and 310,9, the control group – 2770 and 307,1 kg, respectively. Heifers of the 1st experimental group on live weight was significantly outperformed herdmates in the control group: at the age of 3 months by 18,3 kg, 6 months – by 41,7 kg, 9 months – by 55,0 kg, 12 months – by 69,3 kg, 15 months – by 80,3 kg and 18 months – by 74,5 kg (P ≥ 0,999). The advantage of heifers of the 2nd experimental group in the same age periods was 8,8; 24,4 (P ≥ 0,99); 38,7; 48,9; 62,9; 56,2 kg (P ≥ 0,999). The heifers of the 3rd experimental group exceeded their analogues by 5,7; 10,3; 22, 5 (P ≥ 0,95); 27,6 (P ≥ 0,99); 42,9; 39,2 kg (P ≥ 0,999), the 4th experimental group of heifers exceeded their analogues by 2,1; 4,3; 12,9; 10,4; 21,0; 21,7 kg (P ≥ 0,95). Intensive rearing had an influence on the formation of the animal’s body type. Heifers have been raised at the increased level of feeding, especially in the 1st experimental group, are more massive, have a wider and deeper chest, an even and wide rear part with widely set legs.

The reliability of the results obtained in scientific and economic experiments on the study of the effectiveness of the use of various feed components, including biologically active substances in the rearing of broilers needs to be confi rmed in production conditions. The purpose of the research was to study the joint use of enzyme drugs and lecithin in the rearing of broiler chickens. The results of production experiment on the study of the effectiveness of the joint inclusion of enzyme drugs Sunzyme and Sunfyse 5000 as well as lecithin in the diet of broiler chickens of the cross Ross-308 have been presented in the article. Production tests have been carried out under the conditions of the breeding farm “Achkhoy– Martanovsky” in the Chechen Republic. The duration of the experiment was 45 days. For research on the principle of analog groups two groups have been formed: a control group and an experimental group of 1000 heads in each. The broilers of the control group have been fed compound feed prepared in accordance with the growing period and consisting mainly of grain components of local production. The broilers of the experimental group have been fed the same compound feed, but with the addition of two enzyme drugs Sanzyme and Sanfyse 5000 (100 g/t of feed) as well as lecithin (10 g/kg of feed). The results of the production experiment fully confi rmed the data obtained in the scientific and economic experiment. The positive effect of the joint use of the studied enzyme drugs and lecithin has been manifested in all the studied productive traits. In particular, the increase in live weight of broilers increased by 12,1 %, slaughter yield by 3,5 %, the yield of carcasses of the 1st category by 3,0 %. The main economic indicators also found their confirmation: feed consumption per unit of growth decreased by 11,7 %, additional profit was received in the amount of 27308,2 rubles, the level of profitability of broiler rearing increased by 18,4 %.

It is the fact with the introduction of the detailed system of normalized feeding in the livestock industry, the productivity of farm animals has increased by 11,2 %. The obvious solution to the problem of feeding pigs with complete feed is seen in the use of feed and feed additives of local production, which will reduce the final prime cost of the product. The purpose of the work was to justify the use of feed additives Nabikat and Glauconite in feeding sows. During the experiment 3 groups of sows have been formed (a control group and two experimental ones). Sows of the control group have been received the main farm diet, sows of the 1st experimental group in addition to the main diet have been received the feed additive Nabikat (0,20 % of the dry matter of the diet), and the 2nd experimental group Glauconite (0,25 % of the dry matter of the diet). It has been found on the base of researches that the input of the feed additive Nabikat in the diet of pregnant sows has increased the prolificacy of sows by 16,3 %, the livability of piglets by 10,9 %, while the expenditures of feed has been reduced by 20,4 %. The lowest feed and digestible protein expenditures per live weight gain of a pregnant sow and a weaning piglet have been observed in the 1st experimental group when the feed additive Nabikat was included in the diet of sows. The highest feed payment for 1 weaned piglet has been observed when feeding the feed additive Nabikat to sows, which allows producing 24,3 heads of piglets in natural terms, in monetary terms of 1,92 heads. At the same time, it is possible to get an additional profit of 6,9 thousand rubles.

The purpose of the research was to determine the feasibility and effectiveness of using a natural antioxidant of plant origin – dihydroquercetin (DHA), as a biologically active substance, in combination with the main standard diet of broiler chickens. Scientific and economic experience conducted in production conditions on broiler chickens of the "COBB-500" cross allowed us to objectively establish that the addition of the biologically active substance Dihydroquercetin to mixed feed contributes to the increase in meat productivity and safety of broiler chickens. Feeding of broiler chickens was carried out with full-fledged compound feeds, in accordance with the recommendations of the originator for this cross. In terms of energy nutrition and the content of nutrient active substances, they were the same and differed between the groups in the amount of the additive administered. Chickens of the 1st control group received only feed (basic diet), the 2nd experimental group – advanced antioxidant supplement Dihydroquercetin in the amount of 0.5 g per 100 g of feed, the 3rd – 0.75 g per 100 g of feed, and 4th – 1 g per 100 g of feed. The duration of the experiment was 40 days and to clarify the effectiveness of increasing the duration of the broiler fattening period, it was extended to 60 days. Broiler chickens were reared on the floor, temperature and light conditions, air humidity, feeding and watering front of the bird during the experiment corresponded to the recommended standards. As a result of the conducted studies on the effect of adding optimal levels of biologically active feed additive Dihydroquercetin to the diet of broiler chickens, it was found that during the growing period, a higher coefficient of live weight gain was established in broiler chickens of the 3rd and 4th experimental groups, whose live weight increased by 105.32 and 120.48 times by the age of 40 days, while in broiler chickens of the 2nd experimental group by 102.57 times and the lowest–in control group chickens only in 90.96 times. The selected feed additive can be considered as an alternative to the use of feed antibiotics in the feeding of broiler chickens in industrial poultry farming technology.

One of the ways to increase meat resources is to improve the condition of livestock on farms in the Russian Federation. This is due to the fact that when the fatness of the animal increases, the meat yield in the carcass increases. The purpose of the researches was to establish the features of the infl uence of the feed protein additive Biovitel on the growth and development of steers of Hereford breed. In order to achieve this purpose two groups of steers-analogs of Hereford breed (control and experimental) at the age of 6 months per 10 head in each have been formed. The time of the experiment was: the preparatory period of 22 days and the main one 275 days. Steers of the control group have received the main farm ration, and steers of the experimental group have received the main ration and feed protein additive Biovitel for 30 days with 10-days interval at the dose of 100 g per head during the sixth month. The results of researches on the infl uence of the feed protein additive Biovitel on the growth and development of steers of Hereford breed have been refl ected in the article. The addition of the feed additive Biovitel to the main ration of the experimental group of steers helped them to achieve a higher live weight and higher average daily gains under the same environments of feeding and housing in all age periods. By the end of the experiment (15 months) the experimental group of steers have reached the live weight of 430,2 kg, which was higher by 19,9 kg or 4,9 % compared to the control group of steers. In order to improve the quality of beef and increase its production more intensive rearing of steers of Hereford breed with the use of feed protein additive Biovitel has been justifi ed. The recommended dose is 100 g per head. This dosage allows you to achieve the average daily gain of 967,5 g and the average live weight of 430,2 kg by 15 months of age, reduce the prime cost and increase the profi tability of beef production.

Studies conducted in farm conditions, the company, OOO PZ «Nasha Rodina» in Sokolovsky village of Gulkevichsky district of Krasnodar region. The aim of the research was to study the use of the PassPro Soy feed product consisting of protected soy protein in the diets of new-bodied highly productive cows. 2 groups of cows of the red-mottled Holstein breed were formed, selected according to the principle of pairs-analogues: by age in calving, calving time, live weight, productivity for the past lactation, fat and protein content in milk. The ration of the first control group was the ration accepted on the farm for newbodied cows. The diet of the second experimental group was the same as in the first control group, only 1.5 kg of compound feed was replaced with 1.5 kg of PassPro Soy, which is a protected soy protein in the form of a 5 mm granule. During the milking period, the daily milk yield of cows in the control group was 30.80±1.07 kg. The daily milk yield of cows of the second group, where 1.5 kg of compound feed was replaced by 1.5 kg of PassPro Soy, significantly increased by 6.6 %. Due to the increase in the gross milk yield, there is a tendency to increase the amount of milk fat in the milk of cows of the second group by 6.9 %, as well as milk protein by 11.3 %. In the experimental group, when replacing 1.5 kg of feed taken on the farm with 1.5 kg of PassPro Soy, milk productivity increased by 2.03 kg. Additional profit from the sale of milk in the experimental group increased by 48.72 rubles. for 1 head per day. The economic efficiency in the second experimental group was 6.30 %.

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.

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.

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.

Изучены рост и развитие бычков — помесей красной степной с казахской белоголовой породой в равнинной провинции Дагестана. Установлено, что помесный молодняк, по сравнению с чистопородным скотом красной степной породы, имеет более высокую живую массу при рождении на 1,8 кг, или 7,3%. При отъеме в 8-месячном возрасте помеси имели живую массу 210 кг против 187,6 кг у красного степного молодняка, что на 22,4 кг, или 11,9% выше. В 12-, 15- и 18-месячном возрасте живая масса помесных бычков равнялась 291,8 кг, 359,7 и 436,6 кг, соответственно, или на 28 кг, 36 и 45,8 кг больше по сравнению с красным степным скотом. Среднесуточные приросты помесных бычков за период выращивания и откорма составили 760 г, что выше на 12,1% по сравнению с чистопородным красным степным молодняком. После заключительного откорма и убоя помесные бычки дали тяжеловесные туши с хорошим поливом. По массе парной туши они превосходили чистопородных аналогов на 31,3 кг, или 15,6% с преимуществом выхода туши на 2,4%. Убойный выход у бычков опытной группы составил 58,7%, контрольной — 55,8%. От помесных бычков были получены тяжеловесные шкуры массой 27,1 кг, от чистопородных — 21,6 кг, преимущество по этому показателю имели помесные животные 5,5 кг, или 25,4%. Для увеличения производства говядины в равнинной провинции Дагестана рекомендуем скрещивание коров красной степной породы с быками казахской белоголовой породы. The growth and development of bulls of red steppe crossbreeds with the Kazakh white-headed breed in the flat province of Dagestan were studied. It was found that young crossbreed animals in comparison with purebred red steppe cattle have a higher live weight at birth by 1,8 kg or 7,3%. When weaning at 8 months of age, cross-bred bulls had a live weight of 210 kg against 187,6 kg in red steppe young, which is 22,4 kg, or 11,9% higher. At 12, 15 and 18 months of age, the live weight of crossbred bulls was 291,8 kg, 359,7 and 436,6 kg, respectively, or 28 kg, 36 and 45,8 kg more than the red steppe cattle. The average daily growth of cross-bred bulls during the growing and fattening period was 760 g compared to 678 g, that is, they were 12,1% higher compared to purebred red steppe young. After the final fattening and slaughter, the cross-bred bulls gave heavy carcasses with good watering. By weight of the paired carcass, they were superior to purebred counterparts by 31,3 kg or 15,6% with an advantage of 2,4% carcass yield. The slaughter yield of bulls in the experimental group was 58,7%, 55,8% in the control group, respectively, with an advantage in favor of crossbreeds of 2,9%. Heavy skins weighing 27,1 kg were obtained from crossbreed bulls, 21,6 kg from purebred ones, and crossbreed animals of 5,5 kg or 25,4% had an advantage in this indicator. Studies have shown that in order to increase beef production in the lowland province of Dagestan, it is necessary to use crossbreeding of the breeding stock of the red steppe breed with bulls of the Kazakh white-headed breed.
