Abstract

The proposed article explores the effectiveness of using nutrients of forages of Bugayets of various breeds of cattle in the conditions of the Carpathian region of Bukovina. In the studies carried out, it was proved that the first three months, the daily weight gain of young animals in the control group was 661 g, the second – by 13.8 %, and the third – by 22.6 % were less with a likely difference with the control. The absolute gains in the first three months were 60.8; 52.5 and 47.1 kg, respectively, while in the subsequent period (from 3 to 6 months of age) they were high in animals of the second group (92.4 kg), which 9.7 kg (11.7 %) more than the third group and 5.2 kg (5.9 %) more than the first. According to the research results, it can be seen that the milk period of animals hornless beef simmental cattle gave 804 g daily gain, first-generation hybrids – by 2.2 %, and young animals ¾-blood chunks of simmental cattle – by 12.2 % less with a probable difference with control. So the absolute gains were 148.0; 144.9 and 129.8 kg, respectively (P > 0.95). Studies have found that from 15 to 18 months of age the absolute gains in live weight of bulls in the first group were 111.7 kg, in the second – by 7.6 kg (6.8 %) were greater, in the third – by 4.0 kg (3.6 %) less. At the end of the fattening period in all groups of animals, the average daily gains were above 1000 g. As a result, the live weight of bulls of the first group at 18 months of age was 483.3 kg, the second – 461.9 and the third – 447.8 (P > 0.95) kg. The coefficient of variability was high among animals of the Simmental hornless beef cattle breed (7.58 %), and the lowest among ¾-blooded simmental crosses (4.28 %). It was found that the efficiency of raising gobies of different breeds was that the profitability in the sale of young animals in the control group was 16.68 %, the second and third experimental groups – less by 5.01 and 8.42 %, respectively.
