Meat productivity of crossbred young animals obtained from Belgian blue and Hereford bulls

The purpose of the research is to increase the meat productivity of young cattle and the efficiency of beef production by using the high potential of meat qualities of specialized meat breeds when crossed with cows of the combined direction of productivity. In our studies, we analyze the results of crossing Simmental cows with Hereford and Belgian Blue bulls in a comparative aspect with purebred young Simmental breeds. Data on meat qualities after control slaughter of young animals of different origins and the yield of individual cuts of bull carcasses at the age of 18 months are given. Interbreed crossing had a positive effect on the development of meat qualities of crossbred young animals. The carcass weight of the Belgian Blue cross breed was 15.3%, more than the carcass weight of the Simmental bulls and 8.0% more than that of the Hereford bull crossbreed. The superiority of crossbred bulls from Hereford bulls over purebred peers in this indicator was 6.8%. The highest carcass yield was found in half-breeds of the Belgian blue breed - 60.3%, which is 2.8% more than in group 5. Half-blooded animals with Hereford blood had a carcass yield of 1.7% more than purebred Simmentals. The carcasses of bulls of all studied groups were distinguished by good development of muscle and adipose tissue. Crossbred descendants of the Belgian Blue and Hereford bulls had the highest weight and higher yield of the most valuable cuts of the carcass: dorsal-thoracic and hip, in comparison with bulls of the Simmental breed. Purebred bulls of the Simmental breed had more output of the scapulohumeral and lumbar parts.
