Summary. In the Hereford breed, there are 3 types of animals according to body type: compact, medium and tall. They differ in productive and adaptive qualities, which is due to biological characteristics. The aim of the study was to study the influence of the growing season on the formation of meat productivity of the Hereford bulls having different body types. Bulls were grown in two sequentially organized experiments: I experiment – the test period for their own productivity in the summer season, II experiment – in winter season. Young animals were grouped according to body type: group I – medium, group II –compact, group III – young growth of a tall body type. At the same time, the age period from 11 to 15 months in animals is coincided with summer season of the year. The experimental young animals in the second experiment was an analogue of animals from the previous study by origin. In the period from 8 to 15 months bulls were tested for their own productivity using beef cattle breeding technology in the winter. Control slaughter of animals was carried out at 18 months of age. As result of two slaughters, sons obtained from tall fathers who exceeded their peers by 7.0-11.3 kg (4.99-8.31%) and 8.7-9.3 kg (6.43- 6.90%) in experiments I and II, respectively, had larger half carcasses. Moreover, a more pronounced intergroup differentiation both in absolute weight of individual body tissues and in their share in the carcass was recorded during slaughter in the first experiment. According to a number of indicators of meat productivity, sons from tall bulls were preferable; more massive carcasses were obtained from them. At the same time, intensive fat deposition in bulls descendants of compact fathers (Siberian breeding) predetermined their superiority in slaughter yield.

Key words: bulls, Hereford breed, body type, meat productivity, growing season, correlation.
