“…Under the conditions of industrial complexes, the livelihood of animals is completely dependent on the housing system. Farms provide a high number of livestock in a limited area and intensive use, which affects the quality of beef (Smakuyev et al, 2021;Nugmanova et al, 2021).…”

The results of meat productivity of young cattle of beef breeds (Auliekol, Kazakh Whitehead, Galloway, Hereford) depending on the breed, sex, and age (young bulls, steers-calves, heifers, first-calf cows, adult cattle-cows, bulls, calves) grown in the Western Region of the Republic of Kazakhstan during winter, turning winter (pre-spring), early spring and spring periods are given. The animals were divided into three groups according to their breed and growing conditions. The highest slaughter yield among adult animals was found in the cow of the Auliekol breed-63,7% with a pre-slaughter weight of 532.8 kg; the lowest yield was in the cow of the Hereford breed -53,6% with a pre-slaughter weight of 410.0 kg. Studies of young animals showed that the highest and the lowest values were 61.3% in a bull of the Auliekol breed with a pre-slaughter weight of 460.1 kg and 50.8% in a bull of the Hereford breed with a pre-slaughter weight of 372.3 kg, respectively. The proportion of muscle, fat, connective, and bone tissue in the slaughter process is determined. The muscle tissue of the animals of higher fatness in the I and II groups consists of 56.6-57.3% of carcass weight, fat-15.7-16.1%, and connective, bone and cartilage-26.9-27.2%. The muscle tissue of the animals of I and II groups of average fatness amounts to 59.7-60.2% of carcass weight, fat-9.8-10.3%, connective, bone and cartilage-29.8-30.1%, the muscle tissue of the animals of III group of average fatness amounts to 58.4% of carcass weight, fat-10.2%, connective, bone, and cartilage-31.4%. The amino acid content of cattle cuts of different breeds is almost identical in proline-0.68-0.7%, serine -0.76-0.79%, alanine -1.09-1.13%, tyrosine -0.63-0.66%; but there are also significant differences, such as argininefrom 0.65 to 1.27%, lysine-from 0.86 to 1.66% and leucine-from 0.87 to 1.56%. The highest total amino acid content is 13.59% and the lowest is 9.26%. As a result, the food and biological quality of beef depending on breed, age, living conditions, pre-slaughter housing, slaughtering, and production processes.

“…Each organism, as well as the population as a whole, is able to acclimatize effectively only in a certain range of natural and climatic conditions. Significant deviations from optimal environmental conditions lead to overstrain or disruption of organism life processes, which leads to a drop in productive indicators and violations of livestock reproduction [9,10,11].…”

The main and economically priority vector of development of agroindustrial complex of the Russian Federation in the current realities is sustainable production of agricultural products in volumes that not only meet the needs of the population, but also create a certain reserve, able to offset the negative effects of forced production downturns and crises. Beef is a high-quality source of protein in human nutrition. In the conditions of protein diet deficiency the question of increasing the volumes of animal production and, in particular, beef as one of the main traditional components of human diet acquires the special urgency. In this connection, we have set the task to study the indicators of beef productivity of Limousin cattle under the conditions of stabling system in a farm located in the biogeochemical conditions of Voronezh region of the Russian Federation. The researches made show that the meat productivity of cattle of Limousin breed differs significantly in pre-slaughter weight of bulls and heifers amounted 621.33 kg and 449.67 kg, and the slaughter weight of steers and heifers was 385.37 kg and 272.30 kg. The slaughter yield of steers was quite high and was 61.98±1.06%, while that of heifers was slightly lower and was 59.90±0.58%. The most interesting is the comparative evaluation of meat quality in interbreed and age aspects according to its dry matter and water content, protein and fat content, as well as other indicators characterizing the product quality, so the ratio between protein and fat in meat, the water-holding capacity of meat proteins were studied to determine the manufacturability and meat quality. Also, indicators characterizing the chemical composition of the longest muscle of the back were determined.

Pig breeding is one of the leading agricultural sectors that ensures the country’s food safety. In this regard, pig breeding must become a highly profitable branch of the agro-industrial complex due to growth of range of production performance indicators. Various feed additives are the reserve for increasing the productivity of the animals. The most popular feed supplements used today are probiotics and phytobiotics. Modern probiotic preparations are a complex (symbiotic additives) consisting of various strains of bacteria with addition of enzymes, prebiotics, chelating elements, amino acids and biologically active components. The article provides data on use of the probiotic preparation “Profort” and the phytobiotic “Intebio” in feeding of sows in farrow and nursing sows. According to the results of scientific and economic experience it was found that feed additives increased the following indicators: prolificacy — by 1.9–2.9%, size of the young piglets — by 10.4–12.3%, number of mature piglets in the litter — by 10.8–11.8%, rate of survival of the young piglets — by 4.0–6.1%, weight of the piglets litter by the moment of weaning — by 18.0–22.2%. The use of the preparations led to decrease in feed costs per 1 kg of liveweight gain and increased revenue obtained from the sale of the young livestock.
