Effects of diet nutritional on slaughter performances and meat quality of Yunnan semi-wool sheep

Abstract

Abstract: Effects of diet supplement at different nutrition levels on slaughter performance and meat quality of Yunnan semi-wool sheep were investigated in this paper. Forty-eight Yunnan semi-wool sheep were evaluated in a one-factor randomized complete block design with 4 levels. Based on gender and feeding methods, animals were divided into four groups. In each group, 2 repeats with 6 (3♂+3♀) individuals were applied, and two individuals were slaughtered and evaluated at the end of experiment. Slaughter performance, carcass characteristic and meat quality were also improved. An optimized dietary formula was proposed for Yunnan semi-wool sheep. As for 15—25 kg sheep, concentrates with low nutrition level were appropriate for male ones, while concentrates with mediate nutrition level were suitable for female ones, and for 25-40 kg sheep, concentrates with high nutrition level were feasible.
