Abstract
The researches were carried out on sheep of the Kazakh Kurdy semi-coarse wool breed: rams of producers of the Bayyssk type of the same breed were used on uteruses of the Kargali inbreed type. The level and dynamics of live weight for the suckling period and up to 16 (yarki) months of age, as well as slaughter and meat qualities of rams of 2 and 4 months of age were studied in the obtained offspring. The level of live weight for all the studied age periods was the highest in the young stock obtained from crossing of Kargali inbred type mothers with rams of Bayys type producers, the superiority amounted to 6.0-3.9% at birth (rams – yarochki), 4.3-3.3% at weaning and 2.7% at 16 months of age (yarki). The study of features of articles of physique of 4 and 16 months old yaks showed that in these age periods yarks with genotype KPG-B × KPG-K have an advantage over purebred Kargalinsky coevals KPG-K by all measures of physique. In terms of slaughter indices, KPG-B × KPG-K lambs had superiority over purebred Kargala lambs at both age periods of slaughter.
