Abstract
Two cases of atlanto-occipital fusion were diagnosed in Polled Hereford calves. The cause, genetic or environmental, of this abnormality could not be determined. Since relatively minor traumatic forces during birth can cause severe injury in the head region, atlanto-occipital fusion should be ruled out in calves dying acutely after assisted parturition.
摘要
在无角海福特犊牛中诊断出两例寰枕融合病例。这种异常的原因，无论是遗传的还是环境的，都无法确定。由于出生时相对较小的创伤力可能会导致头部区域严重受伤，因此对于助产分娩后急性死亡的犊牛，应排除寰枕融合的可能性。
