Aim. To study the feasibility of using feed additives containing powdered feed preparations with different lactulose content in the amount of 5 g/kg of extruded compound feed together with the main diet in terms of the effect on the quality indicators of raw materials and the natural resistance of the body of experimental rabbits. Materials and Methods. The effectiveness was evaluated after the control slaughter at the age of 150 days in the number of 5 heads from each group. The change in live weight was determined when the rabbits reached the age of 75, 105, 135 and 150 days by weighing on an electronic scale. The physiological state and resistance of rabbits were evaluated by hematological parameters. The obtained materials were processed by the methods of variation statistics. Results. The analysis of dynamics of changes of alive weight of animals showed that feed supplementation with lactulose had a positive impact on the growth of animals the live weight of rabbits in groups I and II were greater at 3.8 and 6.2% absolute increase in live weight during the period of experience increased by 5.3 and 7.9%, respectively, compared to control. At the same time, the effect of supplements on blood parameters should also be noted. In our studies, the rabbits of the experimental groups had an advantage over the rabbits of the control group in terms of the level of red blood cells by 0.94·1012 g/l (18.7%) and 1.12·1012 g/l; white blood cells - by 0.50·109 (7.2%) g/l and 0.59·109 g/l (8.5%), respectively. The level of hemoglobin in the blood of rabbits increased by the end of the experiment in the control group by 3.7%, in I – by 12.5%, in II – by 15.9%. Conclusion. Based on the presented results, it can be concluded that the data on quantitative changes in blood were due to the influence of feed additives, which contributed to an increase in the natural resistance of rabbits, and the best indicators were achieved by rabbits of the II experimental group.

The object of research is the components of feed additives, namely dihydroquercetin, blue-green algae spirulina and organic iodine, in various combinations used in feeding piglets from the first days of feeding and before transferring them to fattening, at the age of 90 days. Three groups of piglets, one control and two experimental ones, were formed according to the principle of analogues. Piglets of the first experimental group received to the general diet, a feed additive MKBA-1, consisting of Spirulina – 1 mg, dihydroquercetin – 3 mg, organic iodine – 1,5 mg per 1,5 kg of live weight per day; piglets of the second experimental group to the main diet received a feed supplement ICBA-1, consisting of Spirulina – 2 mg and dihydroquercetin – 2 mg per 3 kg of live weight per day. The use of dihydroquercetin, blue-green algae spirulina and organic iodine in various combinations in feeding piglets contributed to an increase in the adaptive ability of the body, pathogenetic reactivity and correction of metabolic processes, which provided a higher realization of the genetic potential of pigs. The introduction of feed additives into the diet of pigs contributed to an increase in the bactericidal activity of blood serum in the first experimental group by 1%, in the second experimental group by 14,1%, compared with the control group. The number of white blood cells in piglets of the experimental groups was lower and red blood cells is higher compared to piglets in the control group, which was reflected in the hemoglobin content of blood, which was higher than piglets from the control group by 2% and 8,9%, respectively.

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.

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.

Increasing the production of pork meat requires careful work not only in terms of breeding, but also in the organization of complete feeding of animals, the correct selection of feed and feed additives containing the necessary nutrients. The purpose of the work was to analyze the use of premix in feeding young pigs on fattening. Two groups of fattening young pigs (Large White×Landrace) have been selected for the researches using the method of analogous groups, taking into account the breed, age, and live weight per 20 heads in each group with a live weight of 35 kg. Pigs of the control group have received the main economic diet, and animals of the experimental group have received an additional premix Khutorok at the rate of 10 g of premix per 1 kg of feed. The results have shown that the best age to reach 100 kg was in the experimental group of pigs – 215,8 days, which received premix with feed that characterizes their higher precocity by 36,3 days (P < 0,001) than in the control group of animals. The use of this premix had a positive impact on the livability of young animals, in the experimental group it was by 9,3 abs.% more than in the control group of animals. Thus, the best fattening traits have been possessed by young pigl of the experimental group have been received the premix Khutorok in their diet at the rate of 10 g of premix per 1 kg of feed. The obtained data indicate the feasibility of using the premix Khutorok in the feeding pigs for fattening.

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.

Selenium plays an important role for maintaining complex and adequate nutrition of fattened young pigs. It also has a big biological importance to maintain growth and health, as well as for biochemical and physiological processes This study presents the results of a production experiment to determine the effect of organic and inorganic forms of selenium on growth indicators, immunohematological blood parameters and slaughter qualities of fattened pigs in period I and II. Test feeding with various forms of selenium has been implemented with two groups of analogs (N = 60; n = 30), taking into account age and live weight. The experiment was conducted on castrates of large white breed, which were divided into two groups of 30 heads each following the principle of analogues (taking into account their age, live weight). The studied fattened pigs received standard complete feeds of the SK-5 and SK-6 types for a period of 105 days. Growing pigs were fed with organic selenium for 20 mg/kg as part of the feed 64 mixture per head in the first and second period of fattening, while the animals of the control group were fed with 0.3 mg/kg of the inorganic form of selenium. Including a chelated form of selenium in the complete feed of castrates at the rate established in the course of scientific and economic studies has led to 757 g of average daily gain, which is 8.1% more as compared to the control group. The concentration of red blood cells in the blood of growing pigs fed with 20 mg/kg of selenium chelate increased by 6.3%, hemoglobin – by 2.4%, and white blood cells – by 7.1% as compared to the control. Feeding organic selenium to fattened young pigs contributed to a significant increase in specific units of protein activity by 38.65% (p < 0.01), BASC – by 7.63%, as well as lysis – by 40.06% (p < 0.05), and phagocytic activity by 3.33% in blood serum as compared to the control. The half-carcasses of hogs who had received fed rations including selenium chelate fetured slaughter weight and slaughter yield, respectively, higher – by 6.4 and 0.6% as compared with the control analogues. The use of the established norm of organic selenium in the diets of fattened young pigs according to the results of production testing is economically profitable and contributes to a per-head profit of 420 rubles.
