　　与过去传统人工授精方式相比，了解一次定时授精的好处并不仅仅是节约了精子的用量。

　　这种一次定时授精方式已经越来越多地取代了过去连续3天的标准多重授精方式。

　　国际猪业这个月的主题讨论了这种新方式的好处：

　　1、排卵诱导剂：这种方式使用了新的排卵诱导剂可改善受精率、产活仔数及分娩率。

　　2、公猪选择：上述排卵控制技术有利于公猪选择。

　　3、成本和劳动力：一次定时授精可带来诸多经济利益，如通过缩短配种时间显著节约成本。

　　4、精液品质：除了节约精液数量外，还可进一步提高精液品质及其它因素。

　　5、非生产天数：一次定时授精还可降低母猪的非生产天数。

　　5 benefits of single fixed-time sow insemination

　　Learn how this new trend offers advantages over traditional artificial insemination that go beyond semen savings.

　　The new trend of single fixed-time insemination is becoming a more and more popular alternative to the standard practice of multiple inseminations over a a three-day period.

　　This month's issue of Pig International covers some of the benefits of this new approach, including:

　　ovulation inducers- the use of new ovulation inducters with this approach can affect fertility, number of liveborn pigs and farrowing rate

　　boar selection - controlled ovulation technologies can be effectively employed in boar selection

　　cost and labor - there are considerable economic benefits with the use of single fixed-time insemination, including significant cost savings in the reduction of breeding time

　　semen value - there are potential savings in semen value, but finishing values and other factors should also be considered

　　nonproductive days - single, fixed-time insemination can contribute to a reduction in nonproductive days
