摘要 为了选育优质抗逆高繁新种质,本研究以鲁莱黑猪为母本,遴选高肌内脂肪杜洛克和法系大约克分别作父本,进行杂交制种,对其后代进行生长育肥试验和屠宰肉品质测定。结果显示,杜鲁(DL)、大鲁(YL)平均日增重分别为561.35 g、552.15 g,均显著高于对照组鲁莱(LL)503.09 g(P<0.05);DL、YL的胴体瘦肉率分别为57.16%、55.37%,均显著高于LL 48.02%(P<0.05);YL滴水损失最高为3.62%,显著高于LL2.24%(P<0.01),DL滴水损失3.02%,显著高于LL2.24%(P<0.05);DL、YL肌内脂肪分别为4.32%、3.94%,均显著低于LL7.01%(P<0.01)。以上结果表明,杜鲁(DL)、大鲁(YL)的肥育性能和胴体性能均优于鲁莱(LL),经济效益更高;虽然杜×鲁(DL)和大×鲁(YL)肌内脂肪含量等肌肉品质显著低于鲁莱(LL),但也达到了我国优质猪肉的水平。
