【摘要】 利用不连续系统聚丙烯酰胺凝胶电泳法测定了辽宁绒山羊 (12 6只 )、内蒙古绒山羊二狼山品系 (48只 )、内蒙古绒山羊阿尔巴斯品系 (48只 )的血红蛋白 (Hb)、血清白蛋白 (Alb)、酯酶 (Es )、碱性磷酸酶 (Alp )和淀粉酶 (Am )的多态性 ;发现血红蛋白和血清白蛋白表现为单态 ,而另三种酶表现为多态。结果表明 :血清酯酶共有三种基因型 ,即EsAA、EsAB、EsBB ,受两个共显性基因ESA 和ESB 控制 ;碱性磷酸酶共有二种基因型 ,即Apf和Apo型 ,受两个基因Apf 和Apo控制 ;淀粉酶共有三种基因型 ,即AmAA、AmAB、AmBB ,受两个共显性等位基因AmA 和AmB 控制。各品系间Es、Alp、Am的基因频率有很大差异。AmAB型个体产绒量明高于AmAA和AmBB型个体 ;Apf型个体产绒量高于Apo型个体 ,酯酶只与出生重和双羔率有关更多还原

【Abstract】 Polymorphism of hemoglobin(Hb),albumin(Alb),amylase(Am),alkaline phosphatase(Alp)and esterase(Es) and their relationship with performance trait were studied with l24 Liaoning cashmere goats ,and 48 Erlangsthan strain and 48 Arbus strain of the Inner Mongolian cashmere goats by polyacrylamide gelelectrophoresis.It was found that there were no polymorphism in Hb and Alb in the liaoning and Inner Mongolian goats.But there were polymorphism in Es,Alp and Am in them. Down weight was higher (P<0.01)and down diameter was less (P<0.0l)in the goats with AmAB genotype than in these with AmAA and AmBB genotypes. Goat with Apf genotype had higher down weight than those with Apo genotype.Es did not relate with these.更多还原
