Individual samples of bull semen were treated by filtration to remove immotile spermatozoa and by the addition of 10% heifer serum. There was significantly (P less than 0.01) greater serum-induced agglutination in the filtered than in the unfiltered samples. Head-to-head agglutination was also greater (P less than 0.01) in dilute sperm suspensions when compared to concentrated sperm suspensions.
对公牛精液的各个样本进行过滤处理以去除不活动的精子，并添加10%的小母牛血清。与未过滤的样本相比，过滤后的样本中血清诱导的凝集反应显著更强（P<0.01）。与浓缩精子悬液相比，稀释精子悬液中的头对头凝集反应也更强（P<0.01）。
