Meat productivity of crossbred cattle improved by Red Steppe and Black-motley breeds
The article describes the results of studying crossbred cattle. Under equal keeping conditions and moderate feeding the sons of the Red Steppe mothers and the Red Danish and Holstein fathers (groups I and III) used 7-19% less feed units and 6-15% less protein per 1 kg of weight gain than crossbred bull calves of the Red Steppe and Angler, Black-motley and Holstein breeds (groups II and IV). No regularity was found in the consumption of feed per 1 kg of weight gain between the sons of breed improvers of different categories and interbreed hybrids. There was a similar situation regarding the use of digested protein. As for the effectiveness of feed use at the age of 0-6 months, the best results were shown by the bulls of group I, 6-12 months – group IV, 12-18 months – group III. The revealed superiority in the live weight in the offsprings of individual producers, as well as in interbreed combinations (groups I, III and IV), is the result of the higher energy of their growth during the periods. The improvement of the Red Steppe and Black-motley cattle by crossing them with specialized dairy breeds does not have an adverse impact on the meat productivity and slaughter qualities of crossbred cattle in the conditions of moderate feeding.

Methods of creating highly productive meat herds
The article describes the results of a comprehensive study of the impact of using super-repair heifers from dairy cattle husbandry in combination with interbreeding on the basis of the best gene pool of meat breeds, which made it possible to form a highly productive meat herd in a short time. In this regard, there was a problem of increasing the efficiency of using the available breed resources and choosing the method of breeding cattle in a meat herd. To do this, it is necessary to use a rich gene pool and economically useful traits through interbreeding. Crossbred animals are also distinguished by high meat productivity, and the positive result of crossbreeding is achieved in this case to a greater extent due to the combination effect.

Improve the feeding standards of gobies raised for meat
The article describes the results of the study of the effects of different levels of general and protein nutrition, diets with a reduced level of protein, the effect of synthetic lysine and methionine on digestive and metabolic processes, the growth intensity of young cattle and their meat productivity. According to the results of the study, the norm of fiber in the diets of gobies fed at year-round sites in winter conditions was established. The production inspection showed a high efficiency of detailed feeding standards, as well as little information about the change in the need for animals for basic nutrients depending on climatic conditions when harvesting and fattening livestock at year-round sites.

Nutrition and behavior study of reserve heifers kept on various diets
The article describes the study results of nutrition and behavior influence in reserve heifers kept on various diets. According to the results, it has been established that the diet type forms the certain direction of digestive processes in calves. The diet containing haylage enhances the gastric digestion of the calves and contributes to a high level of digestion. Solo-fodder reduces gastric levels and enhances intestinal digestion and somewhat reduces overall nutrient digestibility.

Grazing efficiency of cattle
Scientific and production experience has been carried out to study the value of the herbs of alpine meadows, where livestock are fed and achieve good results. It is advisable to use natural mountain and pre-mountain pastures for feeding livestock if they begin to be grassed after growing 15-17 cm According to the results of our research, concentrated feeds are also most efficiently used as feeding at the final stage of the burning, that is, during the preparation of livestock for sale for meat.
