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.

The poultry industry in Russia has significant prospects for the development of domestic production of eggs and poultry meat. Insufficient attention is paid to the practical application of enzyme drugs, although numerous studies have proven the effectiveness of these substances in feeding animals and poultry. The purpose of the research was to determine the feasibility and effectiveness of using the multi-enzyme drug Axtra XAP 101 produced by DuPont as part of compound feed for growing broiler chickens. A scientific and economic experiment has been carried out and various doses of the multi-enzyme drug Axtra XAP 101 have been experimentally studied as part of compound feed and the optimal dose in the amount of 7–9 % of the dry matter of the compound feed has been identified. Multi-enzyme drug Axtra XAP 101 influences on indices of meat productivity of broiler chickens. It has been found that this drug increases the average daily increase in live weight of broiler chickens, reduces feed conversion and has a positive effect on the livability of livestock. The highest value for livestock livability has been observed in the 3rd experimental group, where it was 97,67 %, which was by 0,32 % higher than in the control group, by 0,5 % higher than in the 1st experimental group and by 0,57 % higher than in the 2nd experimental group. The European productivity index was the highest in the 3rd experimental group and amounted to 412 points. This indicator was higher than in other groups: higher than the control group by 20 points, the 1st experimental group – by 12 points, the 2nd experimental group – by 5 points. Thus, the effect of using enzymes in wheat and barley diets is to increase and equalize the nutritional value of different varieties and batches of grain. Changing the location and mechanism of microbial fermentation as a result of adding an enzyme also has a positive effect on the health of poultry.

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.

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.

Изучены рост и развитие бычков — помесей красной степной с казахской белоголовой породой в равнинной провинции Дагестана. Установлено, что помесный молодняк, по сравнению с чистопородным скотом красной степной породы, имеет более высокую живую массу при рождении на 1,8 кг, или 7,3%. При отъеме в 8-месячном возрасте помеси имели живую массу 210 кг против 187,6 кг у красного степного молодняка, что на 22,4 кг, или 11,9% выше. В 12-, 15- и 18-месячном возрасте живая масса помесных бычков равнялась 291,8 кг, 359,7 и 436,6 кг, соответственно, или на 28 кг, 36 и 45,8 кг больше по сравнению с красным степным скотом. Среднесуточные приросты помесных бычков за период выращивания и откорма составили 760 г, что выше на 12,1% по сравнению с чистопородным красным степным молодняком. После заключительного откорма и убоя помесные бычки дали тяжеловесные туши с хорошим поливом. По массе парной туши они превосходили чистопородных аналогов на 31,3 кг, или 15,6% с преимуществом выхода туши на 2,4%. Убойный выход у бычков опытной группы составил 58,7%, контрольной — 55,8%. От помесных бычков были получены тяжеловесные шкуры массой 27,1 кг, от чистопородных — 21,6 кг, преимущество по этому показателю имели помесные животные 5,5 кг, или 25,4%. Для увеличения производства говядины в равнинной провинции Дагестана рекомендуем скрещивание коров красной степной породы с быками казахской белоголовой породы. The growth and development of bulls of red steppe crossbreeds with the Kazakh white-headed breed in the flat province of Dagestan were studied. It was found that young crossbreed animals in comparison with purebred red steppe cattle have a higher live weight at birth by 1,8 kg or 7,3%. When weaning at 8 months of age, cross-bred bulls had a live weight of 210 kg against 187,6 kg in red steppe young, which is 22,4 kg, or 11,9% higher. At 12, 15 and 18 months of age, the live weight of crossbred bulls was 291,8 kg, 359,7 and 436,6 kg, respectively, or 28 kg, 36 and 45,8 kg more than the red steppe cattle. The average daily growth of cross-bred bulls during the growing and fattening period was 760 g compared to 678 g, that is, they were 12,1% higher compared to purebred red steppe young. After the final fattening and slaughter, the cross-bred bulls gave heavy carcasses with good watering. By weight of the paired carcass, they were superior to purebred counterparts by 31,3 kg or 15,6% with an advantage of 2,4% carcass yield. The slaughter yield of bulls in the experimental group was 58,7%, 55,8% in the control group, respectively, with an advantage in favor of crossbreeds of 2,9%. Heavy skins weighing 27,1 kg were obtained from crossbreed bulls, 21,6 kg from purebred ones, and crossbreed animals of 5,5 kg or 25,4% had an advantage in this indicator. Studies have shown that in order to increase beef production in the lowland province of Dagestan, it is necessary to use crossbreeding of the breeding stock of the red steppe breed with bulls of the Kazakh white-headed breed.

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 %.

The reliability of the results obtained in scientific and economic experiments on the study of the effectiveness of the use of various feed components, including biologically active substances in the rearing of broilers needs to be confi rmed in production conditions. 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 %.

The purpose of the research is to increase the effectiveness of the supplement Reasil on the growth of milk-fed calves. For the scientific and economic experience, three groups of calves were formed (control, 1 and 2 experi-enced). Groups of animals of 10 heads were formed according to the principle of analogues. The indicators of live weight, growth and blood of calves were studied after Reasil use in a diet: Reasil HumicVet as a liquid form, and Reasil Humic Health – reduced to powder. In the experiment, animals of a black-and-white breed were used. The Reasil feeding in the diet contributed to an increase in the live weight of milk-fed calves in the 1-st and the 2-nd experimental groups at two months of age by 5.65 and 5.48 kg (or by 7.4 and 7.2%), respectively, compared to the indicator of the control group analogues. The average daily growth of calves of the experimental groups exceeded this indicator of control animals by 96 and 82 g, respectively. The blood of calves of the 1st and 2nd experimental groups, showed that hematoglobin was higher by 15.7 and 11.4%, red blood cells – by 16.5 and 15.1%, and the alkaline reserve – by 5.2%, compared with blood of calves from the control group, which indicates the activation of metabolic processes in the body. The total protein amount in the blood serum of animals from the experimental groups increased by 8.4 and 5.9% respectively, compared to the tests of calves from the control group. The albu-min content of animals of the 1st experimental group tested was higher by 5.3%; from the 2nd experimental group there was no significant difference compared to the control. The number of gamma-globulins in the blood of ani-mals of the experimental groups increased, which indicates an increase in defense reaction of animals. The con-tent of calcium in the blood serum of calves from the experimental groups was higher by 8.3 and 5.9%, phosphorus – by 4.8 and 2.4%, which indicates a more effective use of these mineral elements.

Aimed to study the effective use of different doses of cuprum proteinate in the diet of broiler chickens, three groups of animals were formed with 50 chicks in each. Chickens from the 1st control group received cuprum sulphate as a part of compound feed, and animals from the 2nd and 3rd experimental groups received cuprum proteinate. The concentration of Cuprum in the feed in the 1st and 2nd groups was identical, and in the 3rd experimental group the amount of Cuprum was reduced by 25% compared to the control. During scientific and economic experiment, it was found that the replacement of cuprum sulphate with its proteinate with the same concentration in the feed has a positive effect on the average daily gain of broiler chickens, and therefore a live weight. Thus, the animals from the 2nd experimental group exceeded control analogues by 7.5% in average daily gain and by 9.4% in body mass at the end of the experiment. Reducing the concentration of Cuprum in the feed of chickens from the 3rd experimental group by 25% (the source of the microelement is cuprum proteinate) compared to the control also had a positive effect on the productivity of these animals. They exceeded control analogues in terms of average daily weight gain by 3.8%, and in terms of live weight by 5.8%. At the same time the direct correlation between animal productivity and quantity of the consumed feed was noted. Thus, broilers from the 2nd experimental group consumed more feed by 3.3% compared to control peers. The chickens from the 3rd experimental group exceeded controls by 1.5% in this index. Thus, cuprum proteinate is a more efficient source of Cuprum for broiler feed. The concentration of this microelement in the feed of these animals aged 5-21 days should be 18.2 g/t, 22–35 days - 16.8 g/t, 36–42 days - 12 g/t or 16.5 g/t on average during the experiment.
