THE IMPACT OF NEW RESOURCE-SAVING TECHNOLOGIES KEEPING QUALITY OF MEAT CALVES

The publication reflects the results of research lethal qualities of the morphological composition of the carcass, the quality of the cuts of meat bull-calves at the age of 17 months black-and-white breast, Simmental and Volyn meat breeds that were contained in the new resourceusage technology of beef production for conditioning the placement of animals in the reconstructed areas. It is established that under identical conditions of calves of different breeds slaughter the best performance was characterized by animals Volyn meat breed. They had a carcass yield of 61.6 %, from which was obtained the mass of steam carcass 303,1 kg (P ? 0,999), 12 % (P ? 0,999) in comparison with bulls of black-and-white dairy cattle and 4% of bulls of Simmental breed. Chemical composition of average samples of meat bull-calves of black-motley dairy and Volyn meat breeds was dominated by animals of Simmental breed, because they had less fat content.
