摘　　要：凝血因子XI缺陷症(Factor XI deficiency)是荷斯坦牛的一种常染色体单基因控制的隐性遗传缺陷。该病的遗传基础是由位于牛第27号染色体的凝血因子XI基因外显子12上发生的一段76bp序列插入。本研究采用PCR方法对我国13个主要公牛站的571头荷斯坦公牛的凝血因子XI基因进行了全面检测,未发现隐性有害基因携带者和纯合个体。Factor XI deficiency is an autosomal recessive inherited defect in Holstein cattle. Affected animals showed a number of symptoms adversely affecting the reproductive performances of the cows and appeared more susceptible to diseases. The mechanism on this deficiency is the mutation for a 76 base insertion into exon 12 of FXI gene that causes Factor XI deficiency. In this study, based on the PCR method, 571 bulls from 13 bull stations were detected for the genotypes of Factor XI deficiency. No carrier bulls of Factor XI deficiency were found.
