The realization of the genetic potential of farm animals is first of all determined by the complete feeding, which is determined by its balance in accordance with the needs of animals with a certain physiological state and level of productivity. The study of enzyme compositions in the feeding of mammalian farm animals that promote better digestion of incoming nutrients is an urgent issue. Feed enzymes not only increase the digestibility of individual feed components, but also allow you to increase the rate of input of inexpensive raw materials “rich” in anti-nutritional factors without compromising the health and productivity of the animal. The purpose of the research was to study the use of enzyme compositions in the feeding of cattle and pigs. The results of the study of enzyme compositions in the rations of lactating cows during the period of increasing the milk yield and pigs during the period of rearing and fattening have been presented in the article. The input of enzyme additives with a cellulolytic effect in the rations of cows had the positive effect on the digestibility of nutrients in the feeding ration, milk productivity, and the composition of milk. During the first 100 days of lactation milk with natural fat content was produced from cows of the 1st experimental group by 5,5 % more and from cows of the 2nd experimental group by 13,8 % more than from animals of the control group. In terms of 4 % milk the animals of the 1st experimental group exceeded the control analogues by 7,32 % and in the 2nd group by 18,1 %. The input of 1 kg/t of feed in the diet of the multienzyme composition “Kemzaym W” animals allowed us to get 81,7 kg of additional gain, more profi t compared to the 1st experimental group, where the additional gain was 24,7 kg. The use of the multienzyme composition “Kemzaym W” in the amount of 1 kg/t in the diets of young pigs had the positive effect on the digestibility of raw nutrients, on the increase in live weight and average daily gains, on the yield of meat and the quality of carcasses.

The experiment has been carried out on a crossbred stock of young pigs in the period 2015–2017 under the conditions of JSC CHC “Krasnodonskoe” in the Ilovlinsky district in the Volgograd region. The purpose of the research was to study the effectiveness of the effect of the anti-stress drug Feed-Food Magic Antistress Mix in intensive pig rearing on the productive traits and quality of the products obtained, as well as the estimated economic indicators. In order to conduct a scientific and economic experiment at the age of 60 days young pigs were divided into 2 experimental groups (control and experimental) according to the principle of pair analogs. Each group contained 25 heads. The difference between the control and experimental groups was that the animals in the control group have received the main diet, and the experimental group has received the anti-stress drug Feed-Food Magic Antistress Mix in addition to the main diet. In the experimental group of pigs when this drug was administered in the age 180 days the live weight parameter was higher than in the control group by 1,55 kg. Clinical indicators of young pigs were within the physiological norm. The pre-slaughter weight in the experimental group has increased by 4,86 % compared to the control group. Due to the use of an anti-stress drug the slaughter weight of animals in the experimental group has increased by 6,69 %. In comparison with the control group the slaughter yield in the experimental group has increased by 1,18 %, in which this indicator was at the level of 67,62 %. The morphological composition of carcasses in animals of the experimental group was also improved. Meat yield has increased by 0,95 %. The yield of fat and bones has decreased by 0,59 and 0,36 %. The weight of internal organs was also superior in the experimental group of pigs. Due to the use of the anti-stress drug the level of profitability in the experimental group of animals has increased by 11,69 %.

Currently, the existing literature sources on the use of feed additives “Tetra+” and “Glimalask” do not fully reflect the data on the comparative study of their infl uence on the physiological state, meat productivity and pork quality of fattened young pigs. Under the conditions of the Lower Volga region comprehensive researches were carried out in a comparative aspect to improve meat productivity and pork quality through the use of feed additives “Tetra+” and “Glimalask” in the diets of young pigs on fattening. The purpose of the work was to increase the productive and pork quality of young pigs on fattening due to the use of feed additives “Tetra+” and “Glimalask” in their diets. The research was carried out in the period from 2012 to 2019. The experimental part of the work took place under the conditions of the stud farm named after Lenin in the Surovikinsky district in the Volgograd region. The object of research was young pigs of Large White breed. The positive influence of feed additives on the digestibility and use of nutrients in diets, meat productivity and pork quality, physiological indicators and economic effectiveness of pork production has been proven. It has been found that the level of profi tability of pork production was higher in the experimental groups in comparison with the control group by 5,03 and 4,48 %, respectively. At the same time the highest effectiveness has been obtained from the animals of the 1st experimental group, which received the feed additive “Tetra+” in the diet, which allowed to increase the live weight gain by 6,74 %, the level of profitability by 5,03 %. Thus, the feed additive “Tetra+” was the most effective.

In connection with the increasing requirements for the quality of beef, the need for further technological solutions improvement for the cultivation and fattening of beef calves, aimed at improving meat productivity, ensuring not only the quality, but also the safety of meat, has acquired particular relevance. Data on the production of environmentally friendly raw meat obtained in the foothill zone of Karachay-Cherkessia from the bulls of the Aberdeen-Angus breed in modern conditions of the development of the meat industry are presented in the article. During the growth and development of animals, significant qualitative and quantitative changes occur, associated with an increase in weight and a change in the morphological composition of the carcass. The morphological composition of carcasses, meat yield and its chemical composition in the final period of fattening were studied. When calves reached the slaughter live weight, slaughter was carried out and the meat qualities were studied. Carcass weight was 320.2 kg (carcass yield - 57.2%); boneless beef - 266.7 kg (84.9% of chilled carcass). 58.7% (156.6 kg) of the meat was lean; 30.6% attributed to fatty beef. The moisture content of the combined minced meat was 70.9%; protein - 20.4%; fat - 7.7%; ash - 1.0%. Meat safety was determined from the average sample of minced meat. In terms of chemical composition and safety, beef meets the requirements of the interstate standard GOST 32855-2014 for raw meat. Thus, the maintenance and feeding of young cattle on the foothill pastures of the North Caucasus, used later for meat, provides moderate-intensive and extensive feeding with an insignificant inclusion of concentrates in the diet.

The authors highlight that broiler poultry is considered to be one of the most profitable and promising sectors of agriculture. At the same time, industrial technologies experience unsolved problems, such as death of young poultry in the first weeks of life due to the lack of resistible immune system, which is formed by the end of the third week. In this regard, development and application of immune stimulating specimens is a promising direction for stimulation and maintenance of natural poultry resistance and improve its economic parameters. The specimens used should not affect the quality and products safety. The example of such specimen is ImmuGuard; it was tested in the experimental vivarium conditions at the Department of Veterinary and Sanitary Expertise of Livestock Products And Hygiene of Agricultural Animals at the Institute of Veterinary Medicine And Biotechnology of Omsk State Agrarian University. The researchers arranged three experimental groups from Ross broilers on the basis of similarity. 1st experimental group received the specimen dosed 150; second group of broilers -250 g / t of water during 18 days from the date of hatching, and the 3rd group was arranged as a control one. Growth and weight parameters were determined by individual weighing of poultry every seven days. The quality of broilers’ meat was assessed by means of conventional methods used in veterinary and sanitary assessment of poultry meat. The experience showed a positive effect of the specimen on live weight gain of poultry: the authors observed body weight of broilers aged 42 days from first experimental group was 4.12 higher; broilers from the 2nd group 1.39% in comparison with the control group. The authors highlight a significant increase in the average daily growth: the 1st group showed the growth on 32.21% from the 22nd to the 35th day in respect to the control parameters. Organoleptic, physico-chemical and microbiological parameters of meat of all groups conformed to GOST 31470-2012 and SanPiN 2.3.2.1078-01 standards.

The study is dedicated to research into efficiency of influence of probiotic additive “Prostor” on productivity, chemical composition of meat of rabbits. The influence of synbiotic preparation “Prostor” on the population of male rabbits of hybrid form “Hypharm” of French breeding, selected at the age of 45 days. The study took place at the industrial complex of LLC “Lipetsk rabbit” in Khlevensky district of Lipetsk region. The animals were divided into control and experimental groups by the method of pairs-analogues. The control group of rabbits received the basic diet consisting of lall-mash feed PZK-92, while the rabbits of the experimental group received compound feed PZK-92-60-18, which included synbiotic “Prostor” in a dosage of 1 g/kg of feed. Meat quality assessment was carried out at the age of 105 days after control slaughter in the amount of 3 animals from each group. The use of the stated dosage of synbiotic preparation had a positive effect on the productive indicators of rabbits (live weight, average daily growth). The morphological composition data showed that rabbits of the experimental group outperformed rabbits of the control group by 23.84 % in terms of muscle mass. Analysis of the chemical composition of muscle tissue showed that the use of feed additives “ProStor” in a dosage of 1.0 g per kg of feed has a positive effect on meat productivity and quality of rabbit meat, which opens up prospects for the use of the preparation in the rabbit industry.

It is assumed that the combined effect of an effective probiotic and feed bentonites will enhance their positive effect on the growth, development, immunity of poultry, the quality of products, economic results of production. The purpose of the research was to study the effectiveness of the probiotic Vetkor and trace elements contained in bentonites in the compound feed of broiler chickens. Scientific and economic experiment has been carried out in the company “Uksyansky broiler” on broiler chickens cross “Smena-4”, which have been distributed in 3 groups on the principle of analogues. For each group 50 heads have been selected one day-old chickens. The conditions for rearing and housing the chickens were the same. The joint use of bentonite and probiotic in rearing and fattening broiler chickens have been studied. At the beginning of rearing the weight of chickens in all groups was almost the same and averaged 39,6 g. However, with increasing age of chickens not only their live weight increased, but also the difference between groups for this indicator. So, at the age of 7 days the chickens of the 1st experimental group had live weight higher than the control ones by 1,86 %, and the chickens of the 2nd experimental group by 2,00 %. The live weight of the broiler chickens of the control group at the end of rearing (age 42 days) was less than the live weight of the 1st broiler chickens of the experimental group by 101,14 g or 5,23 % (P < 0,05), and the 2nd experimental group by 132,14 g or 6,83 % (P < 0,01). The total and average daily increase in live weight of chickens of the 1st experimental group was greater by 5,34 % (P < 0,05), and the 2nd experimental group by 6,96 % (P < 0,05) than in the control group. Broiler chickens that consumed the probiotic Vetkor in the compound feed had higher growth energy than in the control. Against this background the best growth has been observed in broiler chickens of the 2nd experimental group who consumed compound feed with the addition of Vetkor and 3 % bentonite. It has been experimentally justified the use of probiotic and bentonite in the industrial production of meat of broiler chickens, it has been established a positive effect of probiotics and bentonite on the growth and development of broiler chickens, the quality of the resulting products.

The article presents data on a scientific experiment conducted on quails of the Japanese breed. Data on the influence of the prebiotic drug «BioAxel» on the physiological parameters of quails have been established. The dynamics of the live weight of quails when feeding different dosages of the drug is estimated. In the experiment, the positive effect of different doses of the feed additive «BioAxel» on the average daily and gross growth of experimental birds (by 8,2–16,5% compared to the control) was established. The most effective method was feeding part of the BioAxel (5% of the feed weight) plus another part (4%) with water. A comprehensive veterinary and sanitary examination of quail slaughter products was also carried out when using the prebiotic drug «BioAxel»in the diet. It was found that this drug does not have a negative effect on the quality of meat. At the same time, the indicators of biological safety are within the limits of the norm established by current regulatory documents. In terms of nutritional value, the meat of quails raised with the use of the prebiotic drug «BioAxel» exceeds the meat of quails from the control group. The content of essential amino acids significantly increased in poultry meat of the experimental groups, and the total biological value in the test with Tetrahymena pyriformis exceeded the control parameters.
