家养梅花鹿腹腔镜输精技术研究——CIDR+PMSG同期发情处理后输精时间是关键
Understanding Artificial Insemination in Cervus nippon:The Importance of Time Lag between CIDR-withdrawal-PMSG-injection and AI
摘要
Abstract
Single CIDR devices forty five healthy parous sika does in each of was intra-vaginally placed for 12 days and then randomly allocated to receive 200(n=21) IU or 150(n=24) IU PMSG injection,respectively,at the time of CIDR device withdrawal.Estrus of the females was detected every two hours by the adult sika stag fitted with a mating mark harness and apron after CIDR removal.Laparoscopic AI of the estrus does were performed with frozen-thawed spermatozoa on 2 h after identified estrus.These does were detected with the sires every morning and dusk until November 15.Estrus synchronization rates,rates of the non-returning to service and the fawning rates of the does were investigated and analyzed.It is found that estrus synchronization rates are similar in sika does treated with either 150 IU or 200 IU PMSG at CIDR device withdrawal(86% and 92%);the time from removal of CIDR to onset of estrus is 47.5-49.7 h;the rates of non-returning to service are high in sika does either 150 IU or 200 IU PMSG group(88.9% and 76.2%),but the fawning rate is low(50.0% and 38.1%).We analyzed the effects of AI at different times after CIDR removal on the fawning rate,and an acceptable fawning rate(69.2%) was obtained by AI at 6070 h after CIDR removal,that is very meaningful to determine the opportunity of timed AI for sika deer.关键词
