Abstract

A total of 627 cattle representing seven breeds from south central Nebraska, USA were tested for 37 BoLA antigens which behave as products of 37 distinct alleles of the class I BoLA-A locus. Four antigens were absent from all breeds tested. The other antigens showed marked and statistically significant differences in breed distribution. There was no evidence for blank (null) alleles. The number of alleles in each breed ranged from 10 to 20. The Hereford and Simmental populations tested were less polymorphic than the Angus, Brown Swiss, Charolais, Gelbvieh and Limousin populations.

摘要

对来自美国内布拉斯加州中南部的代表7个品种的627头牛进行了检测，检测的37种牛白细胞抗原（BoLA）抗原表现为I类BoLA - A基因座37个不同等位基因的产物。在所有检测的品种中均未发现4种抗原。其他抗原在品种分布上显示出显著且具有统计学意义的差异。没有证据表明存在空白（无效）等位基因。每个品种的等位基因数量在10到20个之间。所检测的赫里福德牛和西门塔尔牛群体的多态性低于安格斯牛、瑞士褐牛、夏洛来牛、吉尔维奶牛和利木赞牛群体。
