摘要：
The influence of servicing interval, age and servicing month on the spermatological performance of 216 boars was studied on the basis of sperm obtained during 30,106 servicings. Various sperm characteristics showed that these factors have a marked effect on A.I. boar performance. Their effects on the sperm characteristics used as value determinants differ in the order servicing interval > age > servicing month. The application of u-values to compensate for the effects of these factors is recommended in comparative spermatological studies.
