QUALITATIVE BEEF INDICATORS OF THE MIXED BREEDS CATTLE

Abstract

The article presents results of a study of the quality indicators of cross-bred steers raised in the conditions of modern fattening technologies. For the experiment, four groups of experimental young animals were selected: the first group included animals obtained from crossing Kalmyk bulls with crossbred cows from crossing Salers breeds with Simmental; the second group-bulls obtained from crossing Kalmyk bulls with crossbred cows, from crossing Salers bulls with black-and-white cows; the third – animals obtained as a result of crossing Hereford bulls with crossbred cows obtained from Salers bulls with Simmental cows; the fourth-bulls obtained as a result of crossing Hereford bulls with crossbred cows from crossing Salers bulls with Red pied cows. Each experimental group had 30 goals. It was found that the combination of the origin of crossbred animals of ½ blood of the Hereford breed with crossbred animals with ½ blood of the Salers and Simmental breeds contributes to a faster accumulation of live weight compared to their peers, which confirms their high "precocity" and better metabolism in the body. Over the entire period of the experiment, the bulls of the third experimental group outperformed their peers of other groups in terms of live weight dynamics, slaughter indicators and meat quality. Crossbreeding of Hereford bulls with cows with the genotype ½ Salers with Simmental breed contributed to the highest manifestation of the genetic potential of meat productivity in comparison with the studied peers.
