The article presents data on the influence of the complex of micro elements (Fe, Cu, Zn, Co, Mn) in the form of aquacitrate on the indices of non-specific and cellular immunity in chicken broilers. The poultry received a fodder, balanced by nutrients, according to its type, age and productivity. Control group of chickens were added standard mineral premix (SP) from inorganic compounds of bioelements. Broilers of experimental groups were given water with a complex mineral additive of aquacitrates. In particular, the chickens of the first experimental group – in the amount corresponding to their content in the standard premix (SP), and the 2nd, 3rd, 4th and 5th experimental groups – in the amount equal to 3/4, 1/2, 1/4 and 1/10 of the content of mineral elements in the standard premix. It was found that bactericidal and lysozyme activity of blood serum (BASB and LASB) were the highest in broiler chickens of the third and fourth experimental groups and exceeded the control values by 5.7 and 5.3%, respectively. In the bird of the second and fifth groups, the studied indicators were closer to the ones in control. However, in the chickens of the group D1, giving them the highest studied dose of aquacitrate of micor elements, the values of BASB and LASB tended to decrease. Concerning the level of CIC in serum, it was the highest in the chickens of the second, third and fourth groups, the lowest in the group D1. A similar pattern is also characteristic for phagocytic activity of pseudoiesinophils (PhA). The bite of half and even the quaternary amount of citrates of micro elements, compared with the amount of bioelements in inorganic form, provided an increase, compared to control, of PhA. At such a dose of micro elements in the nanoform in the blood of broilers, the number of T-total and T-active lymphocytes increased, including T-heeler cells and decreased the relative number of T-suppressors. The bird of the first experimental group was characterized by a decrease in the percentage of T-heeler against the background of a slight increase of T-suppressors. Thus, the results of studies of indices of nonspecific and cellular immunity suggest that micor elements in the nanodisperse form, due to better bioavailability and high bioactivity, have a positive effect on the formation and development of the immune system in broiler chickens at a dose corresponding to 25 and 50%, from recommended quantity of biometals in the standard premix.

Recently, interest in the use of bacteriophage therapy in poultry has arisen in the context of the growing problem of antibiotic-resistant microorganisms, as the need to find alternative antibacterial agents is urgent. In addition, EU legislation prohibits the use of antibiotics in feed to stimulate the growth of animals and poultry. Bafasal – a new and innovative agent based on natural components of the ecosystem, has a high specificity to Salmonella serovars, in particular, S. enteritidis, S. typhimurium, S. mbandaka, S. gallinarum, S. іnfantis, which are most often diagnosed in poultry farming. This is the first bacteriophage product on the poultry market, which is recommended as a feed additive for broiler chickens. The article presents the results of studies on the safety of Bafasal under the application as a feed additive for the prevention of bacterial diseases in poultry breeding. Bafasal was used for chickens of the experimental group according to the following scheme: from 1 to 14 days of the experiment – per 10 chickens – 50 cm3 of feed additive dissolved to 0,5% concentration; and from 15 to 35 days – 100 cm3 of the drug dissolved to 0,25 % concentration. Feeding of poultry of the control and experimental groups was carried out with identical feeds in accordance with regulatory requirements, taking into account the age of the bird. The clinical condition of the bird’s body was monitored daily, on the 35th day of the experiment; ten chickens from each group were taken blood samples for further laboratory tests. The morphological and biochemical parameters of the broiler chicken’s blood under the application of Bafasal feed additive were studied. It was found that the hematological and biochemical parameters of broiler chickens in the experimental group were within the physiological norm for poultry of this age on fattening, and therefore corresponded to the status of a conditionally healthy organism without signs of pathophysiological abnormalities. There was a reliable increase, within the physiological norm, in the relative number of lymphocytes by 11, 9 % (p <0,05) and a tendency to increasing the number of leukocytes, which showed a sufficient immune potential of the birds and an increase in cellular factors of natural resistance, compared with control chickens. According to the parameters of mineral metabolism, the serum content of Calcium and Phosphorus within the physiological norm was noted, which indicated a sufficient level of mineral supply of the organism of the experimental birds as a whole. In addition, in chicken fed Bafasal throughout the fattening period, the serum enzyme’s ALT, AST and creatine kinase activities and the content of total cholesterol not differ significantly from the control group, indicating the absence of signs of hepatotoxic effects of the studied feed additive.

Complete feeding of ponies is provided on the basis of data on their nutritional needs depending on age, sex, physiological state and level of productivity (the amount of milk produced and the intensity of growth of young animals). Ponies are sensitive to a lack of vitamins and mineral elements in the feed. When there is a sufficient amount of organic and mineral substances, but a lack or absence of vitamins, horses and ponies have impaired metabolism. The purpose of this work is to study the effectiveness of the use of vitamin and mineral additive MEGA-VIT in the rations of pregnant and lactating mares of Shetland pony breed. It has been found during of the researches that the vitamin and mineral additive MEGA-VIT had a positive influence on the productive and physiological indicators of animals. The cost of spent feed for the entire period of experiment in the control group was 50,6 thousand rubles, and in the experimental group it was 11,8 thousand rubles more or 23,5 %. Revenue from the sale of young horses of the control group amounted to 400 thousand rubles, and experimental group – 440 thousand rubles, this is by 40 thousand rubles more than in control group. This led to the increase in profit in the experimental group of mares by 28,1 thousand rubles and accordingly the level of profitability by 3,2 %. It has been recommended on the results have been obtained on the base of researches to include 30 g/head/day in the rations of mares of Shetland pony breed during pregnancy, and 50 g/head/day during lactation.

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 results of research on the influence of the elaborated complex immunotropic drug containing butafosfan, interferon, thistle and fat-soluble vitamins A, D3, E in the form of a liposomal emulsion on the activity of T- and B-cell chains of immunity in rats under the conditions of action on the body of oxidative stress are presented. It has been established that the introduction of 50% tetrachloromethane into the rats of the first and second experimental groups, with a dose of 0.25 ml per 100 g of body weight, causes oxidative stress in them which negatively affects the cellular immunity and functional activity of immunocompetent blood cells. Immunosuppressive effects of oxidative stress were manifested by a decrease in the blood of rats in the first and second experimental groups of the number of T- and B-lymphocytes and their regulatory subpopulations mainly on the 2nd and 5th day of the study. At the same time, in the blood of rats of the first experimental group in all research periods a decrease in the relative number of common, active and theophylline-resistant T-lymphocytes, as well as B-lymphocytes was observed with a noticeable increase in the number of their undifferentiated forms. At the same time, the obtained data suggest the positive effect of butafosfan, interferon, thistle and vitamins A, D3, E in the liposomal preparation on the relative amount of T- and B-lymphocytes and on the redistribution of avidity in the direction of strengthening the receptor field of plasma membranes immunocompetent cells. It was found that the normalization on the 2nd day of blood level in the second experimental group of common T-lymphocytes occurred due to the secondary forms of the blood and active T-lymphocytes by changes in the number of low-avid forms. In addition to the indicators characterizing the cellular immunity of rats, the components of the liposomal preparation showed regulatory influence on the humoral link of the immune response. In particular, on the 10th day of research in blood of rats of the second experimental group a tendency towards an increase in the relative number of B-lymphocytes and an increase in the number of cells with low and medium density of receptors was found, which, under the conditions of oxidative stress, indicates an increase in the body's ability to actively synthesize protective antibodies

The polyacrylamide, mineral and vitamin additives have been added to the sow diet of the 2nd and 3rd experemental groups. It has been done according to the animal need in minerals and vitamins. In proportion of 0,5/1 kg of live weight, the mineral and vitamin aditives, polyacrylamide have been added to the ration of sows from the 2nd experimental group. The mineral and vitamin aditives have been added to the ration of the 3rd group in such proportion: iron sulfate – 200, copper carbonate – 15, zinc – 84, cobalt – 3, manganese chloride – 69, potassium iodide (stabilized) – 170 mcg, vitamins A – 2.8 th. IO, D – 736 IO, B1 – 1.4 mg; B2 – 8.4 micrograms per head per day. The mineral and vitamin additives, polyacrylamide have been added to the sow diet of the 4th experimental group in the same proportion as it has been already mentioned above. The sows fed on PA and MVA for 60 days. The feeding was stopped 10 days before farrowing. The experiment on piglets has been carried out in 2 stages. The equalization period was 25 days (the ration of piglets from the control and experimental group was the same). The main period was 150 days (the control group of animals fed on standard compound fodder). The experimental group fed on additional PA and MVA. It has been noticed when the additives are added to the sow diet the gained piglets have an increase of viability, immun response (due to gamma globulins increase in blood proteins) and the average live weight by 23.3% during the rising period.

In order to increase the meat productivity of broiler chickens, increase production volumes and reduce the prime-cost of poultry products, it is necessary not only to ensure balanced feeding and compliance with production technology but also to include in the poultry diet non-traditional additives, biologically active substances that contribute to the normalization of metabolic processes and improve the digestibility of feed nutrients. One of these dietary additives is Betulin extracted from birch bark, which has antioxidant and immunomodulatory properties. In this regard, the purpose of the research was to study the influence of compound feed with the introduction of 2 % feed additive based on a synthetic microspherical nanoporous carbon carrier containing biologically active Betulin in its composition on the productivity of broilers. The results of studies on broiler chickens using compound feed with 2 % feed additive have been presented in the article. It has been found that the feed consumption per 1 kg of live weight gain in poultry of the experimental group have been lower by 9,5 % due to better absorption of nutrients, the live weight of broiler chickens of the experimental group at the age of 42 days was 2625,6 g and it was higher than the control group by 3,68 %. The digestibility of crude protein and fat reached 92,73 and 88,03 %, which exceeded the control group by 1,03 and 3,03 abs.%, respectively. It has been found that the use of compound feed with 2 % of the feed additive with the biologically active substance is of practical importance in connection with the increase in the productivity of broilers and the level of profitability of meat production by 8,2 abs.%.

The physiological state of animals is to a certain extent characterized by hematological indicators, since blood occupies a special place in the body. By transferring nutrients and biologically active substances, the blood performs the general regulation of vital functions of the body. The use of Vitartil as a feed additive in the diets of animals leads to an increase in glycolytic processes and a decrease in the body’s need for oxygen delivery, which contributes to the growth of the animal body. The purpose of the research was to study the changes in blood parameters taking into account the age of Hereford steers against the background of the use of Vitartil feed additive to the main diet and its effect on the productive traits of animals. In order to carry out the experiment two groups of steers-analogs of Hereford breed have been formed at the age of 6 months per 10 heads in each. The difference between the groups was that the steers of the experimental group have been received the feed additive Vitartil in addition to the main diet. The greater yield of the meat part was in the steers of the experimental group in comparison with the herdmates of the control group. This indicator in the experimental group was 78,9 %, while in the control group it was lower by 1,6 %. The animals of the experimental group were superior to their herdmates in terms of meat weight by 1,4 kg or by 8,8 %. The relative number of bones was lower in the experimental group and amounted to 18,4 %, and in the control group 19,2 %. The meat content index was high in the steer have been received the biologically active additive Vitartil and was 4,3, and in the control group 4,0. It has been found that the use of Vitartil feed additive to the main diet of Hereford steers increases the blood content of hemoglobin and glucose, which has a certain effect on the morphological and chemical composition of meat, as well as increases its energy value.

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 %.
