摘要/Abstract

摘要： 为了研究不同营养水平精饲料对云南半细毛羊屠宰性能及肉品质的影响,采取单因子4水平随机区组试验设计方法,将48只试验用云南半细毛羊按性别各半及饲喂方式分成4组,每组设2个重复,每个重复6只(3公3母)进行饲养试验,试验结束后每组选择2只进行屠宰测定。结果表明,放牧状态下的云南半细毛羊,在补饲不同营养水平精饲料后,其屠宰性能、胴体性状及肉品质有一定程度的改善。建议云南半细毛羊15~25 kg公羊精饲料营养水平可参考本试验前期低水平(DE 12.98 MJ/kg,CP 17.26%)、母羊参考试验前期中水平标准(DE 13.19 MJ/kg,CP 19.59%);25~40 kg云南半细毛羊精饲料营养水平均参考本试验后期的高水平标准进行(DE 13.10 MJ/kg,CP 15.96%)。

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.
