In recent years, Russia has been developing domestic single-purpose meat cattle breeding. Some livestock farms have focused on the production of high-quality grades of raw meat, i.e. ‘marbled’ beef. Meat of that kind is in great demand in the premium meat market. At the same time, production of beef without using steroids and hormonal drugs increases the competitiveness of this product on the world market in countries of the West and the Middle East. Within the framework of our study, an experiment was conducted on Kalmyk cattle in the arid conditions of OAO Kirovskij in the Republic of Kalmykia. Standardized methods of analysis were used. For the experiment, 10-month-old steers were selected and divided into two groups (Control and Test), 30 heads each. They were kept and fed according to different technologies until the age of 19 months. The Test group steers were kept tied up and fed with a diet developed by the Volga Region Research Institute of Manufacture and Processing of Meat-and-Milk Production; the Control group steers were kept according to conventional beef cattle production technology. The wide expansion range and popularity of this cattle breed are caused by the high productivity of steers whether kept tied up or allowed to graze free. The compared qualities of beef obtained from Kalmyk steers proved that keeping them tied up allows increased production efficiency of raw meat which is an important factor for meat production, being intensified in an unstable situation in agriculture

The article presents results of a study of the quality indicators of cross-bred steers raised in the conditions of modern fattening technologies. For the experiment, four groups of experimental young animals were selected: the first group included animals obtained from crossing Kalmyk bulls with crossbred cows from crossing Salers breeds with Simmental; the second group-bulls obtained from crossing Kalmyk bulls with crossbred cows, from crossing Salers bulls with black-and-white cows; the third – animals obtained as a result of crossing Hereford bulls with crossbred cows obtained from Salers bulls with Simmental cows; the fourth-bulls obtained as a result of crossing Hereford bulls with crossbred cows from crossing Salers bulls with Red pied cows. Each experimental group had 30 goals. It was found that the combination of the origin of crossbred animals of ½ blood of the Hereford breed with crossbred animals with ½ blood of the Salers and Simmental breeds contributes to a faster accumulation of live weight compared to their peers, which confirms their high "precocity" and better metabolism in the body. Over the entire period of the experiment, the bulls of the third experimental group outperformed their peers of other groups in terms of live weight dynamics, slaughter indicators and meat quality. Crossbreeding of Hereford bulls with cows with the genotype ½ Salers with Simmental breed contributed to the highest manifestation of the genetic potential of meat productivity in comparison with the studied peers.

Volga region research institute of manufacture and processing of meat-and-milk production, Volgograd 2 Volgograd state agrarian university Продуктивность крупного рогатого скота и сохранение хозяйственно-полезных признаков зависят прежде всего от технологии содержания и полноценного кормления. В работе приведены результаты исследований по изучению эффективности использования при выращивании бычков на мясо привязной и беспривязной технологий содержания. Установлено, что бычки, находившиеся на привязи, отличались от сверстников по интенсивности роста и убойным показателям. Так, в возрасте 16 месяцев живая масса была больше, чем у аналогов, на 7,19%, а абсолютный и среднесуточный прирост  выше соответственно на 19,67 и 18,7%. У молодняка, содержавшегося на привязи, масса туш была больше, чем у сверстников, на 7,39%, масса жира-сырца  на 2,8 кг, убойный выход  выше на 0,50%. По массе мякоти после обвалки туш их превосходство составил 8,35%. По результатам расчета уровня рентабельности производства говядины было выявлено, что для группы бычков, содержащихся на привязи, он был выше на 6,23%. The productivity of cattle and the preservation of economically useful traits depend primarily on the technology of maintenance and full feeding. The paper presents the results of studies on the effectiveness of use in growing bulls for meat of tethered and loose-housing technologies. It was established that the tethers, who were on a leash, differed from their peers in the intensity of growth and slaughter indices. So, at the age of 16 months, live weight was more than that of analogs by 7.19%, and the absolute and average daily gain is higher by 19.67 and 18.7%, respectively. In the young, kept on a leash, the weight of the carcasses was 7.39% higher than that of their peers, the

The article highlights the results of scientific experience in studying the meat productivity of cross-breeding red steppe bulls with genotypes 1/2,3/4 and 7/8 in Angler breed in comparison with pure-bred red steppe bulls. In the course of a complex of scientific research and chemical analyzes, it was found that thanks to the use of Angler breed, it is possible to obtain highly productive young cattle that are superior in quantitative and qualitative indicators of productivity to pure-bred red steppe cattle.
