Scientific studies of foreign and domestic scientists convincingly proved that selenium is a vitally necessary trace element for farm animals and birds with a wide range of biological effects. It performs unique multifunctional functions in the body – structural, catalytic, regulatory, possesses antioxidant, anti-carcinogenic radioprotective, immunostimulant, antiviral, anti-mutagenic, anti-toxic and adaptogenic properties, participates in the formation of mechanisms that determine the reproductive function of animals and birds, affects osteogenesis, participates in the processes of growth and development. In the scientific and economic research the influence of additives of various doses of selenium into mixed fodder on the development of the digestive system in broiler chickens was studied. As a source of selenium, selenite sodium was used. The research was conducted in the production conditions on broiler chickens of the COOB 500 cross. The duration of the experiment corresponded to the period of growing the young for meat and was 42 days. It was established that the use of selenium in the composition of mixed fodder for broiler chickens at doses of 0.3; 0.4 and 0.5 mg/kg positively influenced the development of the digestive system in young, in particular, contributed to an increase in the mass (by 4.1–11.6%) and total length (1.3–3.5%) of the intestine in general, and its thin and thick parts in particular, as well as the mass of the muscular stomach (17.3–23.2%) and liver (3.6–10.0%). The best macromorphological parameters of the digestive system development were chicken broilers, which, during the entire period of growing, mixed fodder, were enriched with selenium at a rate of 0.3 mg/kg. Comparison of the live weight of broiler chickens of experimental groups with indicators of intestinal development, muscular stomach and liver allows us to assume that the digestive systems in them have been developed better and during the growing period they function more actively.

Unbalanced nutrition as well as diseases of infectious and non-infectious etiology lead to a decrease in production and a significant loss of farm animals and birds. To mitigate these problems, various probiotic drugs (probiotics) are introduced into the diets of birds and animals for preventive purposes. The aim of the research was to study the effect of the Vitafort probiotic, containing antagonistic bacteria of the endophytic strain Bacillus subtilis B11, on the body of broiler chickens. The effect of Vitafort was assessed by measuring the live weight and average daily growth of birds. In addition, a morphological study of blood was carried out and the content of Bacillus subtilis in the small intestine was determined. It was found that the endophytic strain Bacillus subtilis B11 improved the intestinal microflora. Thus, on day 5 of its use, the number of microorganisms varied from 4.1 × 104 to 8.2 × 104 CFU/g, and on day 42 the same number varied from 4 × 108 to 5.8 × 108 CFU/g on day 42, the contents of red blood cells, haemoglobin, and white blood cells in the blood of chickens from the experimental group were higher by 6.44%, 3.44%, and 2.11%, respectively, than they were in the control group. Considering the above facts, it can be assumed that the absorption of nutrients in the intestine improved, and metabolic processes were activated due to an increase in the transport abilities of red blood cells.

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.

Poultry farming holds a special place in ensuring the products that the consumers demand, it provides the population with essential food products,such as eggs and meat,that contain vital micro and macronutrients, proteins, lipids, and vitamins. Therefore, the issues of rational, economically feasible feeding of meat poultry, namely broiler chickens, are an urgent task. It is also essential to find effective methods of their application in order to correct the natural resistance and immune and biological reactivity of birds. The purpose of this research is to study the effect of the biological stimulant-Nucleostim on the growth and development of chickens, hematological, and immunological parameters of the blood of birds.This Biostimulant is a purified bovine spleen extract containing at least 1 mg / ml of low molecular weight peptides (nucleotides and nucleosides) formed as a result of autolysis, using dry whey and diatomite as fillers. Onthe application ofNucleostim, the gain in live weight of chickens was increased by 9.7%. At the end of the experiment, the livability of the chicks of the experimental group treated with Nucleostimcame up to 88%, compared with the 72% of the control group. The use of biostimulant had a stimulating effect on the liver of chickens confirmed by the research results presented in the article, as well as contributed to the development of the thymus in the setting of general dystrophy. Thus, it improved chicklivability and increased body weight gain. The biological stimulant-Nucleostim as an adaptogenic, anabolic, and immunostimulatory agent is promising for finding new drugs that improve the health and productivity of poultry.

Animal reproduction is one of the main factors limiting the efficiency of livestock production. Its optimal level is possibly achieved when certain conditions are created for animals. As reproduction is a complex reflex process depending on neuroendocrine regulatory mechanisms, the character and strength of stimuli, which, in turn, is due to a number of factors. Under normal conditions, the body of animals is affected by many different factors, which are appropriately transformed and specified by positive or negative reactions. Inhibitory factors include air pool, saturated with harmful substances and gases, ionizing radiation, poor water quality along with altered redox properties, hypokinesia combined with poor unbalanced feeding, systematic chronic stress, presence of toxic substances in feed, and the deficiency of vitamins and other bioantioxidants in feed or their excessive spending. Of the wide range of genetic and paratypic factors of negative impacts on reproductive capacity, the most common one is alimentary, which causes impaired reproductive function due to deficiencies in the rules, regulations, and feeding regime of animals. In particular, the alimentary can be associated with both general malnutrition (starvation) and overfeeding (obesity). However, the alimentary form of infertility mostly occurs due to low-quality diets when the diet lacks vital components (mainly vitamins, macro-, and micronutrients) or the quantitative ratios of the ingredients are violated. This is possible even if the total nutritional value of the diet meets the established requirements for the physiological needs of the body. Vitamins, micro-, and macronutrients are ecologically deficient factors of disturbance of animal reproductive function, the influence of which is observed on all processes of reproduction, from fertilization to the postpartum period and the preservation of young animals. The pathogenesis of their insufficiency is associated with the violation of steroido-, gameto-, and embryogenesis and the emergence of ante-, intra-, neo- and postnatal pathologies, respectively. Therefore, treatments and prevention measures should be aimed at providing animals with biologically complete balanced feeding and replenishment of the body with vitamins and minerals. However, all these issues remain incompletely studied and need further research.

Abstract. The experiment was performed with a total of 180 day-old, ROSS 308 combination, meat-type hybrid chickens that were divided according to sex into the control group (C1 and C2 with 30♀ and 30♂, respectively) and two experimental groups: GLY-P1 and P2 with pure glycerol (30♀ and 30♂), and GLY-R1 and R2 with raw glycerol (30♀ and 30♂). The chickens received three feeding mixtures during the experiment: the pre-fattening mixture (BR 1) until Day 14, the fattening mixture (BR 2) from Day 15 to Day 30, and the post-fattening mixture from Day 31 to Day 40 (BR 3). 50 % of the soybean oil in feeding mixtures used in the experimental groups (GLY-P and GLY-R) was replaced with pure or raw glycerol at a ratio of 1:2. The feed and water were available ad libitum for consumption. The mean live weight of both male and female chickens in experimental groups on Days 15 and 40 was statistically significantly higher (P≤0.05, P≤0.01) than that in the control group. The consumption of the feeding mixture during the entire 40-day fattening period was higher in female and male chickens in experimental groups. The differences in the mean weight of processed carcass between the control and experimental groups were very significant (P≤0.01). Glycerol obtained during rapeseed processing is a suitable source of energy and can be added in feeds designed for farm animals.

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.

Humic drugs have a wide range of biological activity, affecting the metabolic processes in the body of animals and humans. Humins play a vital role in protecting the intestine from infections and favorably affect its functions, have the potential to suppress mold and bacterial growth, and reduce the level of toxins. When goats received humic substances they had higher milk yields, while significantly reducing total blood cholesterol. Sodium humate administered to broiler chickens increases the live weight by an average of 5–7 % and the livability of poultry by 3–5 %. The influence of humic acid on the quality of laying and egg quality in Japanese quails has been studied. The implementation of socio-economic and environmental programs of the agro-industrial complex provides for the improvement of technologies and technical means for the production of compound feed and protein-mineral vitamin additives for farm animals and poultry. The purpose of the research was to select a vacuum evaporation plant to increase the concentration of humic gel. It has been found that to increase the concentration of humic gel, it is advisable to use a vacuum evaporation plant with an ejector and a steam condenser. Methods for calculating the parameters of the ejector and the pressure reduction process in a vacuum evaporation unit have been developed. The dependences obtained to study the correlation between the area and the diameter of the nozzle water-air ejector, mass flow inject air, water pressure before the working nozzle, pressure inject air, density of the working water, pressure after the ejector, pressure of saturated steam, working temperature of water, temperature inject air, pressure reduction time.

The study was carried out to know the effects of probiotics (Protexin® Boost) supplementation on growth performances and haemato-biochemical parameters of "Shaver Star Bro" broiler chickens during the period from September to October 2003. A total of 20, day-old broiler chickens were randomly assigned into four equal groups (n = 5) as A, B, C and D. Group A was considered as control fed with commercial ration while group B, C and D were fed with commercial ration with the addition of 1 g, 2 g and 3 g probiotics / 10 litres drinking water respectively up to 35 days of age. The results showed that the body weight gains corresponding to the different treatments were differed significantly (p < 0.01) at the 1st, 2nd, 3rd, 4th and 5th weeks of age. The meat yield characteristics corresponding to the different treatments did not differ significantly (p > 0.05) whereas bursa weight differed significantly (p < 0.05) among the different groups. The mean values of Hb, PCV and ESR corresponding to the different treatments were significantly (p < 0.01) differ. Triglycerides, HDL, LDL, SGPT and SGOT values corresponding to the different treatments were also differed significantly (p < 0.01). The findings suggest that supplementation of probiotics has significant effects on live weight gain and haemato-biochemical parameters of broiler chickens.
