摘要
为了测定波尔山羊与唐山奶山羊杂交后代在秦皇岛地区的产肉性能,对(8～10月龄)波尔山羊的杂交一代羊和杂交二代羊进行屠宰测定,并与同龄唐山奶山羊比较。结果表明,杂交二代羊的屠宰率、净肉率、肉骨比、肌肉重、胴体重、胴体产肉率比杂交一代羊分别提高了9 1367个百分点、9 3618个百分点、30.50%、102.29%、90.58%、5 0008个百分点;比同龄唐山奶山羊分别提高了9 3997个百分点、10 8248个百分点、48.39%、204.59%、172.52%、8 1168个百分点;杂交二代羊的宰前体重、胴体重、胴体产肉率、肉骨比等指标均显著或极显著地高于同龄杂交一代羊和同龄唐山奶山羊(p<0.05或p<0.01),胴体品质有明显的改善。
In order to measure the meat performances of upgraded offspring of Boer Goat and Tangshan dairy goat in Qinhuangdao area,the slaughtering experiment of Boer Goat (8～10 months) F1 and F2 was carried out. The results showed that the dressing percentage, meat percentage, meatbone ratio, muscle weight, carcass weight and carcassmeat ratio of F2 increased 22.81%, 33.28%, 30.50%, 102.29%, 90.58%, and 7.1% respectively compared with those of F1, and increased 23.62%, 40.59%, 48.39%, 204.59%, 172.52% and 12.10% respectively compared with those of Tangshan dairy goat. The slaughter weight, carcass weight, carcassmeat ratio and meat bone ratio of F2 were significantly or very significantly(p<0.05 or p<0.01) higher than those of contemporary F1 and Tangshan dairy goat . The carcass quality of F2 was improved obviously.
