| 摘 要： | 采用双垂直薄层聚丙烯酰胺凝胶电泳法，研究了福建黑白花奶牛的免疫球蛋白Ａ（ＩｇＡ）、后清蛋白（Ｐａ）、铁传递蛋白（Ｔｆ）和清蛋白（ＡＬ）等４个位点的多态性。结果表明，福建黑白花奶牛的４个位点都有多态性，各位点的基因频率为ＩｇＡ~A０．７３４４，ＩｇＡ~B０．２６５６；Ｐａ~A０．１２８９，Ｐａ~B０．８７１１；ＴｆＡ０．４３５５，ＴｆＤ０．５０５９，ＴｆＥ０．０５８６；ＡＬＡ０．４３７５，ＡＬＢ ０．５６２５。ＩｇＡ在牛中是新鉴定出来的多态位点，位于γ－球蛋白区前沿，是受一对常染色体等显性基因控制的简单孟德尔式遗传。Ｐａ、ＡＬ也都各自受一对常染色体等显性基因控制，而Ｔｆ由３个常染色体等显性基因控制。计算了群体４个位点平均基因杂合度和位点累积亲子排除率，分别为０．４１４５和３０．００％。

| Abstract: | Blood samples were taken from 143 Holstein cows in Fuzhou and 113 in Nanping respectively at lactating days ranging from 150 to 360 days in lst-3rd lactation period.The both side vestical thin PAGE was used to type genotypes of immune globulin A, postalbumin, transferrin and albumin. The results showed that there were polymorphism on the loci of IgA, Pa,Tf and and ALin Fujian Holstein cows, Overall gene frequencies were 0.7344 and 0.2656 for IgAA and IgAB respectively;0. 1289 and 0. 8711 for PaA and PaB;0. 4355, 0. 5059 and 0. 0586 for TfA,TfD,TfE:0.4375 and 0.5625 for ALA and ALB. IgA was first found a polymorphic locus in cattle. It was one of proteins and controlled by 2 antosomal codominant allelea at a single locus in Mendelian pattern. The population average probability of heterozygozity and the probability of eliminating error parentage relationship for 4 loci were 0.4145 and 0. 30 respectively. |
