PRODUCTIVITY OF BUGAIERS OF DIFFERENT BREEDS AND THEIR MIXTURE AT AVERAGE LEVEL OF FEEDING IN CONDITIONS OF THE FOREST-STEP ZONE OF THE BUKOVYNA REGION

Abstract

The proposed article describes the productivity of ruminants of different breeds and their crossbreeds at an average level of feeding in the conditions of the forest-steppe zone of the Carpathian region of Bukovyna. Thus, the results of the research indicate that Bukovyna zonal-type bulls of the Simmental beef cattle breed prevailed by 134g (19.4%) more than their peers - analogs II - black and spotted breed of the milk productivity direction. According to the results of the control slaughter, Bukovyna zonal-type meat Komologo Simmental bulls had a carcass weight of 218.5 kg, which is 32.0 kg (17.1%) more compared to peers - analogues of the black-spotted breed with a slaughter yield at the age of 15 months - obtained from Bukovyna zonal-type beef cattle Simmental - by 5.5% more compared to similar animals of the black and spotted dairy breed. According to indicators of pre-slaughter weight at the age of 15 - months, the best were the bulls of the meat Komologo Simmental cattle. This indicator in them was on average 461.0 kg, which is significantly greater than that of peers of the Bukovinian type of meat Komologo Simmental (1/2 x 1/2 black-and-white) by 3 kg and 16 kg, respectively. It was established that the difference in the protein content of Bukovyna zonal-type Bukovinian beef cattle of 50% x 50% Simmental was higher than that of peers of the black-spotted breed by 1.07%. Research has shown that hemoglobin in animals of the I, II, III - experimental groups was 89.0 - 90.0 g/l, in the 1st experimental group it was increased by 4.4%, with a norm of 90-100 g/l. Erythrocytes, respectively, from - 6.70 to - 6.90 x 10.12 /.l. with a norm of 6.70-70.00 x 10 12./ l.
