Abstract
The article presents the results of a study of slaughter indicators and morphological composition of bull carcasses obtained as a result of interbreeding. In the 18th and 19th centuries, many breeders willingly applied basic breeding methods to create new breeds. Based on the results of the work, it was concluded that the crossbreeds of the first generation, which were obtained by crossing different breeds among themselves, surpass the primary forms in viability and productivity. An important aspect of industrial crossbreeding is also the improvement of the genetic potential of the herd. By crossing with meat breeds, it is possible to improve the productive qualities of animals, such as weight gain, slaughter yield, meat quality and other characteristics. At the same time, the positive qualities of the mother breed are preserved, which contributes to the production of highly efficient offspring. The importance of breeding breeds with improved economic and biological characteristics is directly related to the production of meat, which is an important source of protein for human nutrition. The crossing of cattle breeds can lead to the production of different genetic material, which can eventually affect the morphological composition of carcasses and the quality of meat. This approach will help improve the quality and competitiveness of meat, as well as provide consumers with high-quality and safe products for consumption. The productivity of animals in meat production depends on their morphophysiological characteristics, which are formed under the influence of heredity and external factors. The quality indicators characterizing the meat productivity of animals are the results of control slaughter and the morphological composition of carcasses. The article presents the results of comparative studies of meat productivity of bulls of different genotypes. 4 groups of bulls were formed. To determine the meat productivity of the experimental bulls, at the end of the experiment, we conducted a control slaughter of 3 heads and studied the morphological composition of the half-carcasses. From the analysis of data on control slaughter, it follows that animals of different genotypes have certain differences in the main indicators of meat productivity. Based on the obtained research results, it was found that the indicators of meat productivity of meat of mixed young animals obtained by industrial crossing with cows of Kalmyk, red-mottled and red steppe breeds were a level higher than those of their peers.
