Abstract

The study results of Aberdeen-Angus breed bull meat production, depending on the body type, are presented. The first group consisted of bulls descended from stud bulls of large tall type, the second group consisted of bulls descended from stud bulls of the small compact type. It was determined that at the age of 18 months, bulls from large-type parents reached a weight of 442 kg, and from small-type parents - 413 kg. The first group bulls had a higher pre-slaughter weight by 31.4 kg and heavy carcasses compared to the second group bulls by 28.3 kg or 13.5% (P > 0.99). The first group bulls, being higher-legged, produced carcasses with a higher bone content (by 4.08 kg) during slaughter compared to the second group. In their carcasses, there was 4.52 kg of boneless meat per 1 kg of bones, while in the second group carcasses - 5.03 kg. However, in general, when boning semi-carcasses of the first group, more boneless meat was obtained, by 9.9 kg. or by 11.72% (P > 0.99) compared with the second group.
