Analysis of external features and live weight of woolly-meaty sheep (ovis aries)

Abstract This article addressed the development and the growth of offspring, the external characteristics and the productivity at different breeding periods of woolly-meaty sheep of Uzbekistan. It was observed that wool productivity was higher in sheep rich in wool-meat than ordinary sheep; sheared wool was 1.26 kg (49.6%), after washing it was 0.97 kg (67.8%), wool length was 2.13 (19.2%) higher. Live weights of lambs from ewes in the experimental groups were determined at birth, at 30 days of age, and 3 months of age. From September 1 to September 20 of the year, the live weight, body size and wool productivity of early inseminated ewes were higher than those of inseminated ewes from late October to November 10. The live weight of lambs obtained from artificially inseminated sheep with frozen semen of typical rams in world gene pool considered semi-fine wool in the meat-wool direction was higher than sheep naturally inseminated with pedigree rams. Accordingly, it was heavier by 00.4 kg (9.3%) at the first day of birth, followed by 0.5 kg (6.8%) at 10 days, and 0.4 kg (1.3%) at 3 months of age.
