为研究精子生育相关性抗原对奶牛妊娠率的影响,测试了16头种公牛精子的生育相关性抗原,进行人工授精,比较奶牛的妊娠情况.结果显示:测试的16头种公牛精子生育相关性抗原,其中13头呈阳性,3头阴性,阴性率为18.75%.在用FAA阳性精液进行人工授精的520头奶牛中,有433头奶牛怀孕,妊娠率为83.26%.而FAA阴性授精的80头奶牛中,只有52头奶牛怀孕,妊娠率为65.0%(P<0.01).因此,奶牛人工授精FAA阳性精子妊娠率比FAA阴性精子高18个百分点,大大提高了奶牛的妊娠率.

In order to study the effects of sperm fertility-associated antigen on cow fertility,sperm fertility-associated antigen from 16 bulls were examined,and cow pregnancy were compared after artificial insemination.The result showed that 13 bulls were FAA posi- tive in sperm membranes,and 3 bulls were FAA negative.520 cows after artificial insemination with FAA positive sperm(at ratios ot 1 bull:40 cows)had 433 cows impregnated,aceraged 83.26%,while FAA negative bulls impregnated only 65%of the 80 cows. Thus,the pregnancy rate of FAA positive bulls were 18 percentage units higher(P<O.01)than that of the FAA negative bulls.The results demostrated sperm FAA can greatly affected the rate of cow pregnancy.
