To evaluate the effectiveness of the “Enzimsporin” probiotic preparation together with grass meal from Jerusalem artichoke green mass for feeding young rabbits, 200 French “Hypharm” rabbits (males) rabbits (males) were selected in the conditions of the “Lipetsk rabbit” LLC industrial complex, which are 45 days old on the principle groups – analogues were divided into 2 groups. Fattening was carried out until the age of 105 days. Rabbits of the 1st group (control) received mixed feed without additives, rabbits of the 2nd group were additionally injected with the probiotic preparation “Enzimsporin” 1.0 g/kg of mixed feed and a sorbent-toxin neutralizer “Fungistat-GPK” 2.0 g / kg mixed feed along with grass meal from green mass of Jerusalem artichoke in an optimally selected dosage of 15% by weight of the mixed feed. Upon reaching the age of 105 days, rabbits of the 1st group (control) were characterized by live weight, which was less than the weight of individuals of the 2nd group - by 284.0 g or 9.80%. The safety of the livestock in the control group was 90%, in the 2nd group 100%. An analysis of the morphological composition of rabbit carcasses showed that the use of the studied feed additives contributes to a more intensive growth of muscle tissue and an increase in the quality indicators and nutritional value of the obtained raw meat. Thus, the “Enzimsporin” preparation together with herbal flour from the green mass of Jerusalem artichoke is a promising product from a number of probiotics used in animal feeding and can increase the productivity and quality of rabbit meat.

The aim of the work is the scientific and practical substantiation rabbits productivity increasing while using Jerusalem artichoke pulp and the probiotic complex "Sporothermin" in the composition of biologically valuable compound feed. The introduction of intensive breeding technologies in the rabbit breeding industry, as well as an increase in the number of livestock, led to a significant increase in the technogenic and microbiological load on the rabbits' body, which in turn causes disruption of digestion, metabolism, a decrease in productivity and the occurrence of intestinal infections. The solution to this problem can be innovative developments on the application of herbal supplements and probiotic complexes in feed rations. They help to improve the bioavailability of nutrients in compound feed and increase the safety of livestock without the use of antibiotics for therapeutic and prophylactic purposes. The influence of the probiotic additive "Sporothermin" together with Jerusalem artichoke pulp on the safety, productivity, physiological status and chemical composition of rabbit meat was studied in the work. 30 rabbits aged 45 days were selected to study the effect of probiotic complexes - Jerusalem artichoke pulp. The control group of rabbits received the main diet, consisting of compound feed PK-90, the rabbits of the experimental groups received compound feed PK-90, which included the probiotic complex "Sporothermin" (0.6 g / kg and 1.0 g / kg) - Jerusalem artichoke pulp 10% by weight of compound feed. The analysis of the chemical composition of muscle tissue showed that the application of the probiotic preparation "Sporothermin" at a dosage of 1.0 g / kg and Jerusalem artichoke pulp at a dosage of 10% to the mass of compound feed increases the average daily gains and, as a result, meat productivity, improves the balance of the chemical composition. This is confirmed by the approbation of the data obtained in the industrial complex of Lipetsk Rabbit LLC and the assessment of the physicochemical, functional, technological and organoleptic characteristics of the raw meat obtained.

The purpose of the study is to evaluate the effectiveness of the use of granular compound feeds with the introduction of probiotic preparation «Prostor», «Sporotermin» and sorbent «Fungistat-GPK» for fattening young rabbits. Studies of the effectiveness of full-size granulated feed were conducted on a population of young rabbits at the age of 45 days, selected according to the principle of groups of analogues and divided into 3 groups in the conditions of a private farm "O. V. Kuznetsova" 15 individuals were selected in each group. The live weight of the experimental groups exceeded the control group's peers when they reached age: 75 days by 85.0 and 251.0 g or 3.99 and 11.80%, 90 days - by 225, 0 and 435, 0 g or 9.04 and 17.49 % and 105 days-139.0 and 245.0 g or 4.37 and 7.70 %. The average daily increase in the control group was 26.55 g, in the experimental group 27.70 and 29.56 g, respectively. Hematological indicators of blood in the experimental groups indicate an increase in the number of red blood cells at the end of fattening (5,35-6,49 1012/l), and there is an increase in the total protein content in rabbits of the experimental groups to 75.82 and 75.99 g/l, which exceeds the values of this indicator of the control group by 3.45 and 0.17 g/l or 4.75 and 0.23%. This trend indicates an intensification of metabolic processes and the possible receipt of the largest increases in live weight. It was found that rabbits of the experimental groups had a slaughter yield of 63.01 and 65.03%, which exceeded the values of this indicator (56.84%) of the control group. The inclusion of enriched compound feeds in feed rations will help to improve the safety and productivity of reared rabbits and creates prerequisites for the large-scale use of these feed resources in the conditions of industrial rabbit breeding.

Aim. Study of the influence of new feed additives on the formation of productivity and quality characteristics in the production of various types of raw materials of animal origin. Material and Methods. Zootechnical, biochemical and mathematical methods of analysis were used in the course of research. The obtained digital material was processed using method of variation statistics, considering the Student-t validation criteria, using the Microsoft Excel software package. Results. As a result of the research, the effectiveness of the use of new feed additives "CoreMix" and "Vitazar" in fattening Kalmyk young bulls has been proved. Over the period of the experiment, the absolute increase in live weight of animals of the I and II experimental groups, who received the tested feed additives, exceeded the control by 8.9 and 18.5 kg, while the feed consumption per 1 kg of the increase in live weight decreased by 0.4 and 0.7 EKE, profit from sales per head was higher by 696 and 1,690 rubles, and the level of profitability increased by 3.1 and 8.2%. The study of the regularities of the formation of beef obtained from young bulls of the Aberdeen Angus breed, when using the new probiotic supplement "Rodafen" in their diets, showed that at the end of feeding, at the age of 18 months, the pre-slaughter body weight in the control group was 463.9 ± 3.29 kg, whereas in the experimental groups that received the test supplement in different doses, this indicator was significantly higher by 3.7%, 4.7% and 3.9%, respectively. For the purposeful in vivo formation of optimal quality indicators of beef obtained from young bulls of the Kazakh white-headed breed, the efficiency of using extruded feed from insects of the Locusta migratoria (ELM) species has been proven. More heavy carcasses were obtained from the young bulls of the experimental group in comparison with their peers from the control group: the superiority in terms of pre-slaughter live weight was 5.8 kg, or 1.41% (P <0.05), in terms of the weight of a fresh carcass – 5.6 kg, or 2.75% (P<0.05). In terms of slaughter weight, the young bulls of the experimental group exceeded the control by 5.4 kg, or 2.53% (P <0.05). In order to increase the energy of growth and meat productivity of the Simmental young bulls, the expediency of using new feed additives "Valopro" and "Ruprokol" has been proved. The introduction of these feed additives into the diet during the rearing period made it possible to obtain a live weight of 439 kg, one kilogram of which contains 403 g of muscle tissue and 429 g of edible parts of the carcass, which is 5-9% higher than in the control. It has been experimentally proven that when fattening large white pigs up to 100 and 120 kg of live weight, it is necessary to maintain the amino acid content at an optimal level by introducing synthetic amino acids, which provides an increase in live weight gain and a decrease in the age of fattening. For the purpose of the intravital formation of high-quality mutton obtained from the Edilbaev breed of rams in the arid Trans-Volga region, the expediency of using a new feed additive containing organic iodine, selenium and silicon in the diets of young sheep has been proven. To improve the quality of rabbit meat, the expediency of using new feed additives based on antioxidants and organic acids has been proven. Conclusion. The expediency of using new feed additives in the production of beef, pork, lamb and rabbit meat has been proven. The use of the proposed feed additives had a positive effect on the feed intake and digestibility of feed, the formation of optimal quantitative and qualitative characteristics of the raw materials obtained, and an increase in the profitability of production.

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.
