The purpose of this work was to establish the characteristics of growth, exterior, payment for feed by gain in live weight among young Aberdeen-Angus breed, originating from bulls of different body types. Hammer LLC of Karachay-Cherkessia conducted the experiment: from the offspring of 4 large bulls and 3 small bulls of the Aberdeen-Angus breed, 14 bulls were selected in each group. The investigation results on the intensive rearing of different young stock from weaning to 18 months of age showed that large-type bulls were superior to small-type bulls in terms of growth rate and better payment for feed by gain in live weight. At the age of 18 months, bulls from large-type parents reached a weight of 442 kg, and from small ones - 413 kg. These differences are statistically significant (P > 0.99) for the period from weaning to one and a half years old bulls, originating from bulls of a large type spent 8.1 EFU per 1 kg of gain, and bulls originating from bulls of a small type – 8.4 EFU.
