Variation in the ovine CAPN3 gene was analysed using PCR-single strand conformational polymorphism, and its effect on growth and carcass traits was assessed in 513 New Zealand Romney lambs produced by 17 unrelated rams. Among the four allelic variants detected, the presence of variant *02 was found to be associated with an increased proportion of shoulder yield (absent: 32.6±0.01%; present: 33.4±0.03%; P=0.016), and tended to be associated with increased shoulder yield (lean meat yield of the shoulder expressed as a percentage of the hot carcass weight) (absent: 16.6±0.06%; present: 17.02±0.20%; P=0.067). No association was detected with growth traits or other carcass traits.
利用 PCR-单链构象多态性分析了绵羊 CAPN3 基因的变异，并在 17 只无关公羊所产的 513 只新西兰罗姆尼羔羊中评估了其对生长和胴体性状的影响。在检测到的四个等位基因变异中，发现变体*02 的存在与肩部产肉率的增加呈正相关（缺失：32.6±0.01%；存在：33.4±0.03%；P=0.016），并且倾向于与肩部产肉率的增加呈正相关（肩部瘦肉产量表示为热胴体重量的百分比）（缺失：16.6±0.06%；存在：17.02±0.20%；P=0.067）。未检测到与生长性状或其他胴体性状相关。
