Therefore the intensification of the dairy cattle breeding industry gives priority to the realization of the genetic potential of dairy productivity of cows, the preservation of their health, good reproductive qualities and the duration of economic use.In this regard, the study of the influence of the intensity of cultivation on the productive qualities of red-and-white cattle is of scientific and practical importance.5 groups of red-and-white animals (20 heads in each group) were formed to conduct the experiments. Feeding was planned to receive an average daily increase in the first experimental group within the range of 850-900 g, the 2nd group received a diet planned for 800-850 g, the 3rd group for 750-800 g, the 4th for 700-750 g and the 5th household diet for 650-700 g of average daily growth. Based on the conducted research, it can be concluded that red-and-white animals are able to grow live weight at a young age, which indicates earliness of animals. Heifers of the first experimental group reached a live weight of 380 kg at 13 months of age, the 2nd experimental group at 14 months, the 3rd experimental group at 15 months, the 4th experimental group at 16 months, and the control group at 17 months. From heifers that reached a live weight of 380 kg and sired at the age of 14-15 months, they were subsequently milked for the first lactation of 6192 and 6345 kg, for all lactation of 24684-24944 kg of milk.

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.

In order to increase the meat productivity of broiler chickens, increase production volumes and reduce the prime-cost of poultry products, it is necessary not only to ensure balanced feeding and compliance with production technology but also to include in the poultry diet non-traditional additives, biologically active substances that contribute to the normalization of metabolic processes and improve the digestibility of feed nutrients. One of these dietary additives is Betulin extracted from birch bark, which has antioxidant and immunomodulatory properties. In this regard, the purpose of the research was to study the influence of compound feed with the introduction of 2 % feed additive based on a synthetic microspherical nanoporous carbon carrier containing biologically active Betulin in its composition on the productivity of broilers. The results of studies on broiler chickens using compound feed with 2 % feed additive have been presented in the article. It has been found that the feed consumption per 1 kg of live weight gain in poultry of the experimental group have been lower by 9,5 % due to better absorption of nutrients, the live weight of broiler chickens of the experimental group at the age of 42 days was 2625,6 g and it was higher than the control group by 3,68 %. The digestibility of crude protein and fat reached 92,73 and 88,03 %, which exceeded the control group by 1,03 and 3,03 abs.%, respectively. It has been found that the use of compound feed with 2 % of the feed additive with the biologically active substance is of practical importance in connection with the increase in the productivity of broilers and the level of profitability of meat production by 8,2 abs.%.

ООО «PskovAgroInvest» pays great attention to the rearing of replacement young animals. The rate of increase in the intensity of raising heifers on the farm meets the standards and requirements of pedigree dairy cattle breeding. The farm uses stage-bystage rearing of replacement young stock, taking into account its age. A group approach to rearing young animals. Replacement heifers use natural and cultivated pastures in the summer. In recent years, the age of replacement heifers at the first insemination has noticeably decreased and approached the norm. At the same time, the live weight of animals at the first insemination increased, which in 2020 amounted to 460 kg, which opens up prospects for a further decrease in the age of the first insemination. This became possible due to an increase in the average daily growth in cultivation, which regularly increases every year and amounts to 756 g in 2020, which is 98 g, or 14.9%, more than in 2016. From table 2 it follows that in recent years, at all age periods, replacement heifers had a live weight exceeding the breed standard, which is 250 kg at 10-month-old, 290 kg at 12-month-old and 390 kg at 18-month-old age. At the same time, an increase in the average live weight of the replacement livestock is observed every year. So, in 2020, the value of the indicator was 278 kg at the age of 10 months, 331 kg at the age of 12 months, 463 kg at the age of 18 months, which is 16 kg, 54 kg and 75 kg, or 6.1%, 19, 5% and 19.3%, more than in 2016, respectively. Thus, the analyzed period allows us to conclude about the effectiveness of zootechnical work to improve the rearing of replacement heifers on the farm, but it must be continued in order to reduce the age of first insemination to 15–17 months with the optimal live weight of the livestock.

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.

The possibility of including SUB-PRO probiotic instead of Maxus G feed antibiotic in the diet of broiler chickens of Ross 308 cross was studied to obtain products free of drugs for antimicrobial resistance usage. The dynamics of live weight and carcass weight of cockerels at 1-, 21-, 28-, 34-, 38- and 42-days old was determined. The males of the control group (group 1) reached live weight of 2619 ± 44.9, experimental - 2739 ± 46.2 or more by 4.38%, at P≤0.05 by 42 days of age, and those which received feed antibiotic ( group 3) - 2677 ± 45.1 (further, meat productivity of the latter was not studied, since they are not of practical importance). The mass of carcasses of the experimental group was equal to 1704 ± 23.1 g, which is 4.60% more than the control, at P≤0.05; the relative mass of muscle tissue increased with age by 10.78% in the experimental group in comparison with the 1-day -olds, in the control group - by 10.0%, whereas the mass of bones decreased by 16.75 and 16.59%, respectively (by the difference); the diameter of muscle fibers of superficial pectoral muscle of 42-day-old broilers of the experimental group increased with age by 6.94 times and amounted to 57.9 μm; in terms of microbiological parameters, carcass meat meets the requirements of the interstate standard GOST 31468—2012. At the age of 42 days, cockerels of the control group showed dystrophic changes in the superficial pectoral muscle in the form of an expansion of the endomysium diameter, with the accumulation of interfiber fluid (albuminous degeneration), while some cockerels of the experimental group have fibers with vacuoles and infiltration by immunocompetent cells (leukocytes, phagocytes). Adding SUB-PRO probiotic in the broilers’ diet instead of the feed antibiotic does not reduce productivity, but excludes the negative consequences of feed antibiotics.

The use of natural sorbents such as aluminosilicates in particular bentonite clays as feed additives is promising now. The diverse mineral composition of bentonites combined with sorbing, buff ering, ion exchange and other features of clay minerals suggest that the physical and chemical properties of clay provide a productive eff ect by activating the regulatory mechanisms of metabolism. The purpose of the work was to identify the infl uence of natural sorbents on the dynamics of live weight and average daily growth of piglets during the fattening period, to determine their meat productivity and meat quality. The biggest infl uence on the absolute gain in live weight over the entire period of fattening was the introduction of 3,5 % bentonite into the diet of piglets (2nd experimental group). This indicator for this group was 71,15 kg, which was 7,65 kg or 12,05 % more than the analogs of the control group. In animals of the 1st and 3rd experimental groups the absolute gain was higher than the control group by 2,98 and 4,93 kg or by 4,69 and 7,76 %, respectively. The average daily gain in live weight during the rearing period was signifi cantly higher in animals of the 2nd experimental group by 64 g or by 12,10 % (P < 0,05). The biggest pre-slaughter weight, the weight of the cooled carcass and the length of the carcass were in animals of the 2nd experimental group. Their indicators exceeded the control group by 5,74, 9,13 and 2,13 %, respectively. The total indicator of the slaughter traits in pigs is the slaughter yield, which was 2,30 % higher in the piglets of the 2nd experimental group than in the analogs of the control group (P < 0,05). It has been found that the introduction of bentonite from the Zyryansky deposit as a mineral additive to the diets of fattening pigs has a positive eff ect on the meat and fattening traits of pigs, the optimal dose should be considered 3,5 % of the weight of compound feed.

Conducting dairy cattle breeding in modern environments is impossible without a deep understanding of all the physiological processes occurring in the body of a highly productive animal. It is well known that the realization of the genetic potential of cows is impossible without the use of high-quality feed products and feeds. The issue of complete feeding of ruminants is particularly acute during the period of increasing the milk yield. The purpose of the researches was to study the feeding of the PassPro Balance feed product consisting of protected soybean and sunfl ower protein in the rations of freshly calved highly productive cows. It has been found as a result of the experiment that the input of the studied additive in the amount of 2 kg in the ration of cows of the experimental group contributed to the increased consumption of feed dry matter by 3,4 %. For the period of experiment from the experimental animals by 12,0 % more milk (P < 0,05) has been received in comparison with the control group. It has been found that the yield of milk fat in the experimental group was signifi cantly higher than the control one by 13,3 % (P < 0,05). In the experimental group of cows there was a tendency to increase the milk protein content by 10,8 %. By adjusting milk yield by 4,0 % in the experimental group of cows this indicator signifi cantly exceeded the control by 12,8 % (P < 0,05). When analyzing the rumen fl uid for microbiological indicators, a certain decrease in enterobacteria and staphylococci has been found in samples of cows of the experimental group with the increase in lactic acid microorganisms by 1,6 times. The pH of the rumen fl uid of cows of both groups was at the level of 6,2, which excludes the development of acidosis in animals during the fresh calving period.

In providing the population with high-quality and cheap beef a signifi cant role is assigned, and in the future will be assigned to beef cattle breeding. The development of this industry and its eff ectiveness depends on the correct use of available feed resources. With the development of the feed industry the main task of which is mainly to ensure that in a small volume, as much as possible, as many sources of nutrients in a highly digestible form, the use of feed additives becomes important. Feed additives as a rule should compensate for the missing elements in the ration. The level and ratio of nutrients in them have a stimulating eff ect on the growth of muscle tissue and the formation of a strong backbone. The purpose of the work was to study the eff ect of the feed additive Vermiculite on the live weight of Kazakh White-headed steers. In order to study the feed additive Vermiculite in the rations of steers a scientifi c and economic experiment has been carried out on the basis of LLP “Terra” in the Kostanay region in the Republic of Kazakhstan. Two groups of steers have been formed for this purpose with 10 heads in each. The control group has received a basic feeding ration consisting of corn silage, haylage, wheat straw, complete feed (wheat, barley). The experimental group has received 200 g of Vermiculite per 1 head/day in addition to the main ration. During the entire period of the experiment the steers of the experimental group had the highest indicators of average daily growth compared to their herdmates in the control group. The highest value of the average daily gain in both groups has been observed in the period of 8–12 months, amounting to 1123,3 g in the control group, and 1159,2 g in the experimental group. The diff erence in favor of the steers of the experimental group was 35,9 g or 3,2 % (P < 0,01). In general during the experiment the diff erence in the average daily gain in live weight between the groups was 31,1 g or 3,5 % in favor of the animals of the experimental group.

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.
