Abstract :
The article presents the studyof the acclimatization ability of the Angus steers of Australian selection in
the conditions of sharply continental climate of the Lower Volga Region of Russia.The steers of Reproduction II have
been established to have a more optimal hematologic composition in comparison with their analogsof Reproduction
I. Their red blood count was more by 3.5%, hemoglobin by 1.42 and total protein by 1.70%. The album in protein
fraction was higher by 7.22%. Bactericidal leukocyte activity of steers of Reproduction II was more than that of steers
of Reproduction II by 2.89%, lysozyme activity by 5.39 and phagocytic activity by 2.86%.The steers of Reproduction
II were taller in comparison with their analogs, but inferior to them in terms of the measurements that characterize
the body width.The growth intensity of the Angus youngsters of Reproduction II was insignificantly higher than that
of their peers. With respect to the overall live weight gain, they exceeded the steers of Reproduction I by 4.2 kg and
to the average daily gain by 17.5 g.In terms of the hot carcass weight, the control slaughter showed the young cattle of
Reproduction II to exceed their analogs of Reproduction I by 6.39 kg or 2.46%, carcass yield by 0.45% and weight of
flesh in carcasses by 5.22 kg or 2.46%. The average carcass flesh sample of the Reproduction II steers contained more
dry matter by 0.13, protein by 0.07 and fat by 0.05%.The profitability of meat production in the group of cattle of
Reproduction II was higher by 2.1%. Thus, the animals successfully passed acclimatization. The results of the research
showed that the bulls of the second reproduction have productive qualities that are comparable to those of the I
reproduction and even surpass it in linear growth and slaughter.
