In world practice biologically active drugs are widely used at different technological stages of rearing pigs, poultry and cattle. Special attention should be paid to bio-grugs obtained not as a result of chemical synthesis, but isolated from organs and tissues of healthy animals. Restoration of normal intestinal microflora of the animal is the basis of the concept of probiotics. Currently, probiotics are considered as endogenous intestinal microflora most often belonging to the group of lactobacilli, streptococci or bifidobacteria or as specific growth factors for them. Probiotics are selected according to certain criteria based on scientific knowledge of the physiology of intestinal microbiology, as well as animal nutrition. The purpose of the work was to study the effect of biological products on resistance, reproductive, fattening and meat productivity of pigs, on the quality of whole-muscle and fine-structured pork products; to develop a method of application of duodenum extract in combination with probiotics to increase the productivity of pigs. Studies on the effect of extracts derived from endocrine cells of the intestine, in combination with probiotics on the productivity of pigs of Large White breed and the quality of pork, as well as studied the effect of duodenins and probiotics in different concentrations on the protective properties of animal blood have been carried out. New methods of application of extracts of endocrine cells of intestines and probiotics for increase of meat productivity of animals and quality of pork have been offered. The use of bio-drugs increased the livability of young animals in all experimental groups from 1st to 4st by 3,51; 6,05; 4,95 and 5,90 %, respectively. There was an advantage in the amount of revenue from the sale of products of all experimental groups over the control one.

The purpose of the work was to study and identify the main factors aff ecting the quantity and quality of beef produced and sold in the Southern Federal district. A comparative assessment of the growth, development, formation of meat productivity and quality of beef of young animals of beef, dual and dairy breeds with stall-pasture technology and intensive rearing in the industrial complex. Experimental studies have been carried out in farms in the Rostov region. The object of research was cows with calves of Kalmyk, Hereford, Aberdeen-Angus, Russian komolaya, Kazakh White-headed breeds, as well as young animals of the same breeds, in addition, Black-and-White and Swiss breeds. Removable live weight in Hereford steers at 18 months of age was 658,0 kg, and Aberdeen-Angus – 655,2 kg. Domestic steers of Kalmyk were 41–44 kg lower in live weight than their herdmates of two imported breeds. However, with intensive rearing at 18 months of age, steers of Kalmyk breed had a removable live weight of more than 613,7 kg and a carcass weight of 326 kg. The yield of hot carcass was 55,4 %, and the slaughter yield was 58,89 %, which was only 1–2 % lower than the world’s leading beef breeds. It has been found when analyzing the results of boning the half-carcasses of experimental steers that the biggest weight of half-carcasses and the content of muscle and fat tissue in them in absolute terms were in Hereford steers. Steers of Kalmyk breed took the third place in terms of weight of large-sized semi–fi nished products and signifi cantly lost to Aberdeen-Angus herdmates by 7,3 kg or 6,5 %, and Hereford steers by 9,2 kg or 8,3 %. The results obtained prove the expediency of using stallpasture technology in the dry-steppe zone of the Southern Federal district when rearing young animals for beef up to 350–400 kg live weight at 15 months of age and its subsequent intensive rearing under industrial technology, in order to obtain the live weight of more than 570 kg and produce cost-eff ective beef.

Purpose: studying the features of the formation of signs of meat productivity in chickens of the egg-meat direction in the juvenile period in ontogenesis and fixing the most informative age for early assessment of meat qualities.Materials and methods. Young grew in group cells of a 3-tier cellular battery. The dynamics of growth and the development of exterior and interior indicators, characterizing meat productivity in ontogenesis in the young of the Pushkin breed of chickens, which refers to an egg-meat type on productivity through periodic (every 2 weeks) weighing and taking protections of the physique in 100 heads of young people. On 21 heads, an anatomical cutting was carried out at which the mass of the heart, liver, two parts of the stomach (muscular, iron), the sum of the muscles (femur, crus, metatisium) took into account. The development of meat forms of the physique to determine the age and individual characteristics was determined using exterior articles of industrial (the length of the body, the length of the keel, the gripping of the chest, the length of the leg, hips, plus). Prombs were taken from the entire experienced livestock, together with weighing, every 2 weeks. In order to find the most informative age for an early estimate of meat quality, which would characterize meat productivity at an older age, the correlation was calculated between the industrial over the age periods and the mass of muscles at 16 weeks.Results. The dynamics of the average daily growth of the living mass and the mass of the carved carcass in the roosters was uneven. Until 8-week age, the average daily increase increased, then began to decline until 14 weeks of age, during 16-week aged an average increase increased dramatically. The dynamics of average daily growths in the roosters of individual muscles was similar, namely, from 4 to 8-week age, high rates of average daily growth were noted, and from 8 to 14 months of age there is a decrease, and then again activation of growth. Studies have shown that the growth of the skeleton is slowed down by 14 weeks. The dynamics of the average daily growth of internal organs in the roosters in the juvenile period occurs asynchronously. The greatest intensity of the growth of the heart, liver and stomach was observed on a 8-week age. Studies have shown that the stomach is most intensively developing up to 8 weeks, then development is braked sharply.Conclusion. Based on the data obtained, it can be concluded that for the preliminary selection of chickens of the egg-meat direction of cultivation with the best genetic potential for meat productivity, it is possible at 8 weeks old, but the final rating should be carried out no earlier than 14-week age. The estimation of meat qualities in a 14-week age should be carried out on the basis of live masses and industrial, namely, the oblique length of the body, the girth plus, the length of the leg, the preliminary estimate can be done in such a precursor, as the slanting the length of the body, the length of the leg and girth plus.

When studying indicators that characterize the quality of meat and its nutritional value as part of the development and improvement of existing research methods, histological analysis of the tissues included in it becomes increasingly important. Histological method has been used to study the microstructure of muscle tissue (m. longissimus dorsi) and chemical composition in sheep of diff erent genotypes and reared at diff erent feeding levels. It has been found that the muscle tissue of sheep obtained from crossbreeding of breeds North Caucasus (SC) with Texel (T) has been characterized by a large amount of muscle fi bers by 5,0 and 11,3 % (P < 0,05), the smaller amount by 5,7 and 18,6 % (P < 0,05) in diameter, a higher “marbling” score by 5,2 and 8,3 points, and the lower content of connective tissue by 0,8 and 1,3 abs.% compared to purebreds North Caucasian and from crossbreeding North Caucasian with Poll Dorset breed (PD). Chemical analysis of meat revealed a tendency to increase the content of dry matter and fat by 1,1 and 0,1 abs. % in lamb genotype T×SC and less than the amount by 1,1 and 0,1 abs.% moisture compared to purebreds and PD×SC. Increasing the energy supply of sheep, regardless of breed affi liation, contributes to the formation by 10 % more number of muscle fi bers per unit area and the decrease in their diameter, which increases the “marbling” of lamb and increases its consumer quality. The results have been obtained indicate the feasibility of using morphometric indicators of muscle tissue in the development of criteria for assessing the quality of sheep meat productivity, intended for practical use in agriculture and the meat industry.

The results of evaluating the breeding value of rams of different genotypes by a wide range of productivity indicators of their descendants are presented. Tribal rams of the Kharkov interbreed type of Prekos breed of 2-3 years of age, as well as crosses from the introductory crossing of Prekos sheep with the Romanov breed and Merinolandsheep, were evaluated. The resulting offspring were grown under the conditions of one production flock. The evaluation considered the indicators of the reproductive ability of ewes, sex and type of birth of the offspring, the safety of lambs from birth to 20 days of age, the dynamics of the average daily growth of daughters in the uterus and at the age of birth to 20 days and from 21 to 90 days, live weight indicators were considered, cutting and length of hair of daughters at the age of 14 months. Studies have established that the average yield of lambs throughout the sample was 115.3 % per 100 ewes, with significant differences between the estimated producers - from 105.1 to 131.3 %. This indicator did not have a definite relationship with the genotype of the estimated sheep. Among the offspring of all rams, males slightly prevail over females in the ratio of 1.09 to 1. This advantage is due to the large number of rams born among same-sex twins. Their part exceeded 28 %, while only 23.4 % turned out to be similar in type of birth. By the sum of the ranks that were put to individual sheep for the indicators of the average daily growth of daughters at different periods of their growth, the best cross-breed sheep No. 1625 and No. 9953 are distinguished. On the whole, there is a fairly clear tendency for a positive relationship between the ranks for the growth rate in the embryonic period and the same indicator for posterity aged 21-90 days. According to both the ranking and the probity-based evaluation results, ram No. 1625 (a created line based on crossing with the Romanov breed) is assigned to complex improvers. The rest topping ram out to be improvers of individual traits, and the producer of the breed Prekos No. 1823 was an improvement in production of wool and length of staple. Ram No. 1960 turned out to be a complex deteriorator in the quality of offspring. The descendants of rams No. 4464 and 9953, derived from the breed of Merino landscape, reliably (p≤0.01), by 18.6-20.8 % in terms of wool coefficients, are inferior to the daughters of ram No. 1823, breed Prekos, which is an unconditional evidence of the strengthening of their characters meat productivity over wool one.

Vegetable feed additive “Biostrong 510” based on essential oils and plant substances contains active substances exclusively of vegetable origin, which have a more intense eff ect on the animal’s body. The mechanism of action is based on the synergism of several plant substances containing active substances that, when combined, aff ect a certain category of animals. The additive contains essential oils, herbal plants, and seasonings such as anise oil, thyme oil, gentian powder, chili paprika powder, and quillaya extract. The purpose of the research was to determine the feasibility and eff ectiveness of fortifi cation of compound feed with the vegetable feed additive based on essential oils and vegetable substances to increase meat productivity and meat quality. In order to study the eff ectiveness of feeding vegetable feed additive in compound feed for broiler chickens under the conditions of LLC “Akashevskaya poultry Farm” in the Republic of Mari El, a scientifi c and economic experiment has been carried out. Experiments have been performed on broiler chickens of the cross Cobb-500 from the daily to 40-day age of the birds. The eff ect of the vegetable feed additive “Biostrong 510” based on essential oils and vegetable substances on meat productivity and nutritional value of broiler chicken meat has been studied in the paper. The level of feeding and the quality of the feed consumed by poultry has a big infl uence on meat productivity. The use of our selected vegetable feed additive based on essential oils and vegetable substances increase the slaughter weight by 9,0–13,7 %, the slaughter yield by 2–5 %, the amount of muscle tissue and meat qualities of carcasses. The best results have been obtained by including the vegetable feed additive based on essential oils and plant substances in the amount of 0,015 % of the dry substance of the feed.
