| Research Abstract |
Blood coagulation factor XI deficiency is a hereditary disorder observed in Japanese Black cattle. While the clinical condition of this disorder is mild, the economical impact of this disorder is apprehended to be serious because of the remarkably high allelic frequency of the mutant allele in the population of Japanese Black cattle. We, therefore, investigated the effect of the factor XI deficiency on defects in pregnancy and delivery and carcass traits using large samples of Japanese Black cattle. As a result, we found that affected animals of factor XI deficiency have a tendencies for increased frequencies of abortion and stillborn, but no effect on the condition of calf and carcass traits. These findings will be useful to future breeding of Japanese Black cattle.
