摘　　要：采用聚丙烯酰胺凝胶电泳 (PAGE)对 37头甘肃黑猪合成系猪的转铁蛋白 (Tf)、前白蛋白 (Pa)、脂酶 (Es)、淀粉酶 1 (Am1 )、淀粉酶 2(Am2 ) 5个蛋白质基因座的多态性进行了检测。并运用通用线性模型分析了这 5个蛋白质基因座的共 1 7种基因型对初生重、 45日龄内平均日增重的相关效应。结果表明Am1AA型具有显著提高初生重的效应 ,PaAA型具有显著提高 45日龄内平均日增重的效应。因此这 2个位点可望用于标记辅助选择。In order to understand the relationship between blood protein polymorphism and productivity of Gansu black pig(n=37),vertical polyacrylamide gel electrophoresis(PAGE)was used to analyse the polymorphism of 5 blood protein loci of Tf,Pa,Es,Am1 and Am2.The general linear model was conducted to estimate the effect of protein polymorphism on the performance.The results showed that the birth weight of pigs with Am1 AA genotype and daily gain of live weight with Pa AA genotype were significantly higher than those with other genotypes.These two loci could be as the genetic markers for marker assisted selection(MAS).
