Abstract

The article presents the results of a study of meat productivity and quality of beef obtained from young Kalmyk breed and crossbred bulls. In the course of the analysis of the indicators of the slaughter qualities of the experimental young animals, it was found that the content of meat in the carcass of crossbred peers is higher than that of animals of the Kalmyk breed. An analysis of the results of deboning showed that crossbred bulls are characterized by higher meat qualities compared to bulls of the Kalmyk breed. This can be explained by the manifestation of the effect of heterosis. In the process of research, a positive correlation was found between meat productivity and pre-slaughter weight of bulls. The relationship of some traits depending on the genotype is due to the phylogenetic stereotype of animal development and does not depend on the breed. On the other hand, it, on the contrary, has a significant effect. In this regard, the study of the influence of certain elements of influence on the formation of productive qualities and the identification of the relationship between them on the basis of a thorough correlation analysis made it possible to determine the main parameters of the most effective combination of young cattle genotypes for modeling the breeding process in beef cattle breeding.
