The effect of pyridoxine hydrochloride on the body mass of animals, absolute and average daily increment, relative growth rate, growth factor of live weight and multiplicity of increase in live weight of calves in the early stages of postnatal ontogenesis were studied. For the experiment, six groups of one-day calves (control and five experimental) were formed, with 5 animals in each, which, in addition to the main diet (MD), fed pyridoxine hydrochloride in different doses, according to the scheme: control group – MD, I experimental group – MD + 1 mg/kg g. m pyridoxine hydrochloride, II – MD + 2 mg/kg g. m of the preparation, ІІІ – MD + 3 mg/kg of w. m., IV – MD + 4 mg/kg g. m and V experimental group – MD + 5 mg/kg g. m pyridoxine hydrochloride. Conditionally, the research was divided into four periods: colostrum – from birth and up to 5 days, until the formation of digestion – from 5 to 21 days, the period of the formation of digestion scar – from 21 to 60 days and the end of the milk period – from 60 to 90 days. It was established that feeding to calves with pyridoxine hydrochloride resulted in an increase in the live weight of 60 days of calves by 5.9% in the second group (P < 0.05), by 8.7% in the third group, by 8.3% in IV and 9.2% in V groups (P < 0.001) and for 90 days it was higher by 9.3%, 9.1%, 9.2% and 9.1% respectively (P < 0.05). The highest average daily increments were in the colostrum period in calves IV and V groups, which were added to the main diet, respectively, 4 and 5 mg/kg b.w. pyridoxine hydrochloride, in the period prior to the formation of digestion scar in calves of group IV, in the period of the formation of digestion scar in calves of the III group and at the end of the milking period in calves of group V. Absolute incresements of calves in the colostrum period and the period prior to the formation of digestion scar were the highest in calves of Group IV and the difference in control was respectively 0.34 and 1.05 kg. During the period of the digestion scar formation and the end of the milk period, the highest absolute increases were in calves of group V, which was added to the main ration of 5 mg/kg b.w. pyridoxine hydrochloride. The highest increase in body weight of calves in colostric period and prior to the operation scar rate was in group IV, the period of digestion scar formation was in the third group and during the completion period of milk in the second group of calves. In colostric period the increase of live weight was higher in calves III, IV and V groups of 5 to 21 days in calves of group IV, from 21 to 60 days in the third group and during the completion period of milk in the second group of calves.

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.

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 aim of the study is to increase the productive qualities of broiler chickens by including ultrafine silicon oxide into main diet. During the experiment, the biological effect of ultrafine silicon oxide on broiler chickens was estab-lished. Use of ultrafine SiO2 particles for poultry feeding contributed to an increase in the number of red blood cells and content of total protein and albumins. By the end of the experiment, the number of red blood cells in birds in-creased by 17.43% (P≤0.001) – in the blood of birds of the first experimental group, 16.51% (P≤0.01) – the second one, 20.80% (P≤0.001) – the third experimental and 21.71% (P≤0.001) – the fourth experimental group, compared with the indicator of the control group. The amount of total protein in blood serum of chickens of the first and the second experimental groups increased by 1.36-1.39 %, in the third and fourth ones there was a significant (P≤0.05) increase by 5.45 and 3.05%, respectively. The blood glucose content of chickens in the experimental groups is higher by 8.04-23.65% compared to this indicator with ones in the control group. During the experiment feed con-sumption per 1 kg gain of live weight decreased: in the first experimental group by 3.00 % in the second by – 0.50 %, the third – 6.00 % the fourth– by 4.50 %, compared to this with the control group. The chicken’s vibrancy of the first the experimental group was higher by 4.77 %, the second – by 6.20 %, the third – by 19.25 % and the fourth– by 11.59% than in the control one. Consequently, when converting the feed energy into the body energy of a broiler chicken, the energy conversion coefficient of the experimental group of poultry is higher than that of the control one by 7.16-21.76 %. Thus, the most optimal dose for further research was determined.

The article gives scientific substantiation of using silicon-containing new feed additive “Energosil” for replacement gilts. The studies were conducted in pig-breeding complex of the Center for Practical Training of Agricultural Specialists in Mordovia Republic. There were three experimental groups of replacement gilts (10 animals each). The effect of various dosages of Energosil (5.0, 7.5, and 10 mg per kg of body weight) on digestibility, nutrient utilization, and animal growth energy was studied. The most optimal dosage of a new feed additive in their rations was revealed, which constituted 5 mg / kg of the animal live weight. It was established that the animals from the first experimental group, who received silicon-containing feed additives of this amount digested the nutrients of the diet better than their counterparts from the other groups. Compared to the control group, the digestibility of dry matter increased by 3.62% (p<0.05), organic matter by 3.29% (p<0.01), crude protein by 4.09% (p<0.001), fat by 4.30% (p<0.01), cellulose by 3.79% (p<0.01) and nitrogen-free extractives by 2.03% (p>0.05).Replacement gilts of the first experimental group, who were given Energosil in the amount of 5 mg / kg body weight in addition to the basic ration, retained nitrogen in their bodies by 17.1%, calcium by 55.9% and phosphorus by 69.7% more than their counterparts from the control group. It contributed to an increase in body weight of gilts from the first group compared to control counterparts by 10.8%. Increased dosages of Energosil (7.5 and 10 mg / kg body weight) also had a better effect on the growth energy of gilts compared with the control group. The feed additive in the amount of 7.5 mg kg of animal  live weight contributed to an increase in animal weight compared with control counterparts by 6.21 kg or 4.8% (p<0.05), with a third experimental group by 4.4 kg or by 3.4% (p<0.05). When given Energosil in the dosage of 10 mg/kg, the body weight of gilts from the third experimental group was higher by 1.81 kg or 1.4% (p> 0.05) compared with the control counterparts.

The purpose of the research is to increase the effectiveness of the supplement Reasil on the growth of milk-fed calves. For the scientific and economic experience, three groups of calves were formed (control, 1 and 2 experi-enced). Groups of animals of 10 heads were formed according to the principle of analogues. The indicators of live weight, growth and blood of calves were studied after Reasil use in a diet: Reasil HumicVet as a liquid form, and Reasil Humic Health – reduced to powder. In the experiment, animals of a black-and-white breed were used. The Reasil feeding in the diet contributed to an increase in the live weight of milk-fed calves in the 1-st and the 2-nd experimental groups at two months of age by 5.65 and 5.48 kg (or by 7.4 and 7.2%), respectively, compared to the indicator of the control group analogues. The average daily growth of calves of the experimental groups exceeded this indicator of control animals by 96 and 82 g, respectively. The blood of calves of the 1st and 2nd experimental groups, showed that hematoglobin was higher by 15.7 and 11.4%, red blood cells – by 16.5 and 15.1%, and the alkaline reserve – by 5.2%, compared with blood of calves from the control group, which indicates the activation of metabolic processes in the body. The total protein amount in the blood serum of animals from the experimental groups increased by 8.4 and 5.9% respectively, compared to the tests of calves from the control group. The albu-min content of animals of the 1st experimental group tested was higher by 5.3%; from the 2nd experimental group there was no significant difference compared to the control. The number of gamma-globulins in the blood of ani-mals of the experimental groups increased, which indicates an increase in defense reaction of animals. The con-tent of calcium in the blood serum of calves from the experimental groups was higher by 8.3 and 5.9%, phosphorus – by 4.8 and 2.4%, which indicates a more effective use of these mineral elements.

Introduction. Nutrition has a great effect on the quality of life and longevity. Modern food industry pays much attention to the issue of obtaining high-quality and safe livestock products grown without feed antibiotics. The research objective was to study the effect of chamomile extract on a complex of economically useful traits of young rabbits and the qualitative characteristics of meat, as well as to determine the optimal dosage of chamomile extract. Study objects and methods. The experimental research was carried out on the animal farm of the Kuzbass State Agricultural Academy in 2018. Five experimental groups and one control group of young Californian rabbits were formed according to the principle of analogue pairs. Each group included 10 rabbits. From 70-day age, the animals of the experimental group I were supplemented with a phytobiotic feed additive based on wild chamomile extract at a dose of 0.5 g per rabbit per day. In experimental group II, each rabbit received 1 g per day; in experimental group III, it was 1.5 g per rabbit per day; in experimental group IV – 2.0 g per rabbit per day; in experimental group V – 2.5 g per head per day. The experiment lasted 30 days. Results and discussion. The best result was achieved in experimental group II. In the experimental groups, the rabbits demonstrated an increase in hemoglobin. The use of phytobiotic feed additives in the diet did not cause any pathological changes in internal organs. The average live weight at the end of the experiment, compared with the control group, was higher: experimental group I – by 0.82%, experimental group II – by 6.96%, experimental group III – by 5.01%, experimental group IV – by 3.73%, experimental group V – by 2.80% (P ˃ 0.01). An analysis of the chemical composition of rabbit meat after the experiment showed that the water content in the rabbit meat ranged from 76 to 77%, which suggests high water-holding properties. The high dietary qualities of the rabbit meat depended on the content of protein (20–22 wt%) and the low fat content (5–7%). These data make it possible to promote rabbit meat for dietary products. Conclusion. According to the slaughter indicators and the phytobiotic feed additives parameters of meat, the optimal dose of phytobiotic feed additives is 1 g per head per day.

The scientific work considers the selection method of selection in a herd of producers of rainbow trout Kamloops, taking into account values of positive correlation of some morphometric characteristics and degree of development of their reproductive products, as well as the features of natural protective functions of their body at the age of three. It is established that the somatic structure and, development of postorbital region largely determine the functional features of trout, as well as their reproductive qualities. In the indirect selection of three-year-old breeders, taking into account morphometry and correlation, females with a size of postorbital head region greater than 55 mm exceeded by 29.2% the live weight and by 40.4% the weight of trout caviar with a length of this head region less than 55 mm. When comparing the resistance of two experimental groups of three-year-old breeder flock, certain differences in immune proteins and hemoglobin content in blood were revealed. Note that in the selected group of fish, a large degree of saturation of red blood cells with hemoglobin is observed, which indicates increased share of oxygen absorption by the body, as well as the intensity of redox processes of metabolism. Indicators of serum proteins of trout in experimental groups vary ambiguously. So in the experimental group, producers had an average total protein in blood of 63.26 g / l, which is significantly 17.5% more than in the blood of fish in the control group. This can be explained by the relationship of the globulins with the immune status of fish of experimental group and its resistance by raising the level of globulin fraction, a high amount of Ig M` protein (by 42.9%) in the blood of trout in the experimental group suggests more aggressive immune system in these fish to viral, invasive and other infections, indicating improved adaptability of selected herds.

Under the environments of the Tyumen region a scientific and research work has been carried out, including an assessment of the influence of antimicrobial substances: colloidal silver, antibiotics and organic acids on the body of broiler chickens. The purpose of the work was to evaluate the influence of antimicrobial substances on the productivity of broiler chickens. The research and laboratory experiment has been carried out in the laboratory of the Northern Trans-Ural Scientific and Research Institute of the Tyumen Scientific Center of Siberian Branch of Russian Academy of Sciences on chickens of the cross ArborAykrs+. Chickens at the daily age have been distributed according to the principle of balanced groups-analogues. The period of chicken rearing was 35 days, during the same period the analysis of the studied antimicrobial substances has been performed. The composition of the test substances was included colloidal silver 10 μg/l, antibiotics (Pulsoceril, Enronite) and the mixture of organic acids (Agrofeed) at the dose of 0,4 ml/l. The results have shown that chickens that have been watered colloidal silver had the gain of live weight for the period of rearing 1850,94 g or lower than chickens in the control group. At the same time, broiler chickens with watering of antibiotics and organic acids exceeded the control group’s analogues. For example chickens of the 1st experimental group where colloidal silver has been watered at the dose of 10 mcg/l every day had the live weight gain during the rearing period lower by 15,56 g and the average daily live weight gain of 0,45 g than chickens of the control group. At the same time broilers of the 2nd experimental group (with antibiotics) and the 3rd experimental group (with organic acids) had the higher gain of live weight during the rearing period by 56,61 and 95,23 g, respectively, compared to the control group. The average daily gain diff erences were 1,62 and 2,72 g. Indicators of morphological and biochemical composition of blood of experimental groups of broiler chickens indicated that they were within the limits of the corresponding physiological norms. At the same time, there were some changes on the part of both red and white blood, which seems to be related not only to the body’s response to feeding, but also to the biochemical processes within the body.
