摘　　要：应用随机整群抽样方法 ,对太行山羊的两个群体共 72只成年羊 ,用淀粉凝胶电泳法测定了 3 3个血液蛋白座位 ,并对毛色和外形特征进行了检测。结果表明 ,运铁蛋白 (Tf)、前白蛋白 -3 (Pa-3 )、肽酶 -B(Pep-B)、碱性磷酸酶 (Alp)、亮氨酸胺肽酶 (LAP)和酯酶 -D(Es-D) 6个血液蛋白座位表现多态性 ,多态位点比例为0 .1 81 8;1 2个类别 2 5种外型特征中 7个有变异体 ;4个毛色座位有变异。平均杂合度分析表明 ,太行山羊变异程度较大 (H =0 .0 5 5 5 ) ,说明太行山羊群体有效规模较大 ,目前尚未面临急待保种的局面。The genetic examination was carried out on two populations (n=72) from Taihang Goat with 33 blood protein loci examined by starch gel electrophoresis four coat color loci and 12 appearance features by random cluster sampling in Taihang Mountain area. The results showed that polymorphism was found at six blood loci of Tf?PA 3?Pep B?Alp?Lap and Es D,the proportion of polymorphic loci (P poly ) is 0.1818, and four coat color loci and 7 appearance features. And the result of average heterozygosity(H=0.0555)analysis indicated that Taihang Goat have more variability and more effective size of population,and still have not faced the sense of urgency of breed preservation.
