A yearling Rambouillet ram with an asymmetrical scrotum was examined for potential breeding soundness prior to use in a synchronized mating program in a purebred flock of 20 ewes. Initial sperm cell evaluation revealed 78% knobbed acrosomes associated with few other abnormalities of the head and midpiece. Use of the ram resulted in no conception in one group of ten synchronized ewes. One month later, the proportion of sperm cells with knobbed acrosomes was 80%.
在一个拥有20只母羊的纯种羊群中，一只一岁的兰布耶公羊阴囊不对称，在被用于同步配种计划之前，对其繁殖健全性进行了检查。最初的精子细胞评估显示，78%的精子顶体呈瘤状，头部和中段几乎没有其他异常。使用这只公羊后，一组10只同步发情的母羊均未受孕。一个月后，顶体呈瘤状的精子细胞比例为80%。
