DAIRY BEEF PRODUCTION OF DIFFERENT GENOTYPES

Abstract

The aim of the research was to study meat and slaughter indicators, which allow to judge the qualitative characteristics of animal productivity, quantity and quality of final products in bulls of Ukrainian black-spotted dairy breed and crossbreeds F1 1/2 Ukrainian black-spotted and 1/2 Swiss dairy breeds at 18 months of age. The results of scientific and economic experiment on comparative study of meat and butchering slaughter indicators of pure bred young cattle of Ukrainian blackspotted dairy breed and crossbreeds F1 ½ of Ukrainian black-spotted and ½ of Swiss dairy breeds are presented. It was found that the addition of blood of the Swiss breed had a positive effect on the better productivity of local animals in different periods of cultivation in comparison with purebred animals. According to slaughter yield, local bulls outnumbered purebred counterparts by 0.8%. The boning of the diverting weir of the experimental animals made it possible to establish the ratio of pulp, bones, cartilage, tendons and ligaments. In terms of muscle yield, local animals of the experimental group had a significant advantage over control counterparts by 2.8%
