钙蛋白酶抑制蛋白(calpastatin,CAST)对肌内蛋白降解、肌细胞生长速度以及屠宰后钙蛋白酶的活性具有重要的影响,研究CAST基因多态性的遗传效应及其与营养水平的互作影响对猪胴体品质的控制具有重要的作用.实验使用杜洛克和大围子2个纯种猪群,杜洛克×(长白×大白)和大白×大围子2个杂种猪群,利用Hinf Ⅰ,Msp Ⅰ和Rsa Ⅰ 3种内切酶研究了CAST基因的RFLP及其与营养水平互作对猪胴体性状的影响.结果表明,Hinf Ⅰ、Msp Ⅰ和Rsa Ⅰ 3种内切酶在4个猪群均获得RFLP,酶切位点分别存在1对等位基因A与B,C与D及E与F.AA基因型×高营养水平互作显著降低熟肉率和滴水损失.但与中营养水平互作却显著提高滴水损失...

Calpastatin gene（CAST） plays an important role in muscular protein degradation, muscle cell proliferation and post-slaughter calpain activation.Study on interaction effects of polymorphisms of CAST gene and nutrition levels has an essential role in the regulation of pig carcass quality.Interaction effects of polymorphisms of CAST gene at HinfⅠ, MspⅠand RsaⅠsites and three nutrition levels on meat carcass traits were studied among four pig population including Duorc, Daweizi, Duroc ×（Landrace× Large White） and Larege White × Daweizi.Th...
