Abstract

This article describes the beneficial economic characteristics-productivity, exterior characteristics and growth and development of offspring of fleshy-woolly sheep of Uzbekistan in different breeding periods. In terms of wool yield, fleshy-woolly ewes outperformed native breed ewes. In this case, the amount of wool at shearing is 1.26 kg (49.6%), the weight of wool after washing is 0.97 kg (67.8%), and the length of wool is 2.13 cm (19.2%) higher. Lambs obtained from ewes in the experimental groups were determined at birth, 30 days, and 3 months of age. Ewes inseminated early from September 1 to September 20 had higher live weight, body size and wool productivity than those inseminated later, from October 20 to November 10. At the same time, it made it possible to introduce artificial insemination of fleshy-woolly ewes with frozen seeds of rams belonging to the global semi-soft woolly gene pool in the meat-wool direction. The live weight of lambs obtained from them was higher by at birth - 0.4 kg (9.3%), at 10 days - 0.5 kg (6.8%) and at 3 months - 0.4 kg (1.3%) compared to the live weight of lambs obtained from natural insemination of fleshy-woolly ewes with rams.
