摘要
本试验对荷斯坦奶牛常规精液和性控精液配种效果进行了比较分析.结果表明:采用性控精液(200万个/0.25 mL)配种的总受胎率为58.3%,1次性配种受胎率为58.3%,生母犊率为77.5%.采用常规精液(1 000万个/0.25 mL)配种的总受胎率为79.2%,1次性配种受胎率为56.2%,生母犊率为45%.1次性配种受胎率常规精液和性控精液差异不显著(P>0.05),生母犊率性控精液极显著高于常规精液(P<0.01).通过经济效益分析表明,采用性控精液配种可以有效地提高奶牛养殖的经济效益.
Comparison of holstein cow breeding between sexual control semen and ordinary semen was analyzed.The results showed that the total conception rate was 58.3% after breeding with sexual control semen(2 million seeds/0.25 ml).The conception rate by first insemination was 58.3%.The rate of female calves was 77.5%.The total conception rate was 79.2% after breeding with ordinary semen(10 million seeds/0.25 ml).The conception rate by first insemination was 56.2%.The rate of female calves was 45%.The differences of the conception rate by first insemination were not significant(P〉0.05).The rate of female calves by using sexual control semen was significantly higher than that by using ordinary semen(P〈0.01).Through analysis of economic benefits,itis indicated that breeding with the sexual control semen could increase economic benefits.
