阴道黏液电阻值动态变化在梅花鹿同期发情监测及最佳输精时机判定中的应用
Application of dynamic changes in vaginal mucus resistance for estrus monitoring and optimal timing of sperm insemination in sika deer
摘要
Abstract
To investigate the practical effects of vaginal mucus electrical resistance(VER)used for estrus detection and optimal timing of artificial insemination in female sika deer,fifty-six healthy does were synchronized using a CIDR+PMSG+LHRH-A3 protocol.VER values were measured with a vaginal electrolyte analyzer at four time points:CIDR insertion(day 0),CIDR withdrawal(day 12),artificial insemination(day 15)and post-insemination monitoring(day 24).Serum levels of estradiol(E₂),luteinizing hormone(LH)and progesterone(P₄)were used as hormonal references.At the estrus peak(day 15),VER reached its nadir[(325±48.69)Ω],which was significantly lower than at the other three stages(P<0.01).The VER nadir coincided with the peaks of E₂ and LH and the nadir of P₄,showing a typical estrous hormone profile.These findings demonstrate that monitoring VER changes could provide a reliable and timely method for assessing estrus status and determining the optimal insemination time in sika deer.关键词
