HEMATOLOGICAL PARAMETERS OF EXPERIMENTAL BULLS OBTAINED AS A RESULT OF INTERBREEDING

Abstract

The article presents the results of studies of the morphological and biochemical composition of the blood of experimental bulls obtained by crossing bulls of the Russian Komola breed with cows of Kalmyk, red-mottled and red-steppe breeds. In modern animal husbandry, the task of increasing the productivity of beef cattle is inextricably linked with ensuring a reliable hematological and biochemical balance in the animal situation. Blood health reflects a variety of processes: from the efficiency of metabolism and hormonal effects to resistance to stress and infectious influences. In this regard, a detailed analysis of the blood composition becomes a crucial factor for assessing the condition of young animals and the effectiveness of the villages used. Increasing knowledge about how genotype and breed affiliation affect the main biochemical markers of blood in young beef cattle is of practical importance for the development of more effective breeding and application programs. The data obtained provide a better understanding of the balance between the preservation of basic vital functions and important adaptive features, which can positively indicate the stability of the status and economic efficiency of the farm. The results of this study make it possible not only to describe the current biochemical and hematological parameters, but also to develop practical recommendations on the choice of parental equality in interbreeding, which can ensure not only an increase in the rate, but also the preservation of the stability and adaptability of animals to the conditions of detention. The results of this study can be used to carry out additional selection during interbreeding aimed at improving stress resistance, immune protection and general health of young beef cattle, which, in turn, affects the productivity and economic efficiency of farmers.
