家畜定时输精技术研究进展与应用现状
Research Advances and Application Status of Timed Artificial Insemination (TAI)in Farm Animals
摘要
Abstract
With the wide application of the artificial insemination (AI)in animal husbandry,the utilization rate of excellent sire got greatly improved.The key point of AI is predicting the time of ovulation and insemination accurately.It is also the point which the animal husbandry technolo-gists highly concerned to improve the application effect of AI.Estrus and ovulation are regulated minutely by reproductive hormones in vivo in farm animals.Timed artificial insemination (TAI) is based on the synchronization of estrus and ovulation,both of which are triggered by reproduc-tive hormones.So the optimal time for AI could be determined from the reproductive hormone treatment.The purpose of TAI is to improve the reproduction performance of farm animals,re-duce the workload of identification of estrus,and promote batch management.This review mainly summerized the principles of TAI and its applications status,and the prospects was also dis-cussed.It would provide a reference for the research and application of new reproductive technolo-gy in farm animals.关键词
