摘要

本研究的目的是探讨产后第一次发情繁殖前后联合子宫灌洗和催产素给药对母马妊娠率的影响。选取分娩后3 h内胎膜释放的母马30匹,分为对照组(n=10)、孕前治疗组(n=10)和孕后治疗组(n=10)。育苗前组在育苗前4 h,育苗后组在育苗后4 h进行子宫灌洗。两个治疗组分别在子宫灌洗后立即和灌洗后12小时静脉给予催产素两次。对照组静脉滴注0.9% NaCl无菌溶液。对照组分娩至首次排卵间隔时间(14.6 d)较治疗组明显延长(p<0.05)。对照组的怀孕率;育种前和育种后处理组分别计算为40%、40%和60%。尽管在繁殖前和繁殖后处理组均未观察到早期胚胎丢失,但对照组的这一比例为25%。综上所述,在繁殖母产后首次排卵前后4 h给予子宫灌洗(1升0.9%的无菌NaCl溶液+4.000.000 IU结晶青霉素+4g硫酸链霉素)和20 IU催产素,可缩短分娩与排卵之间的天数间隔。可以假设,在马驹发情期繁殖可以有效地减少子宫复旧、与繁殖和胚胎死亡相关的炎症反应。

The Effect of Uterine Lavage and Oxytocin Administration Before and After Breeding on Fertility in Mares in The First Postpartum Estrus
DOI : 10.26650/actavet.2019.398037 The objective of this study was to investigate the effects of the combination of uterine lavage and oxytocin administration before and after breeding during post-partum first estrus on the pregnancy rates of mares. Thirty mares whose fetal membranes were released within the first 3 h after parturition were divided into three groups - the control (n=10), pre-breeding (n=10) and post-breeding treatment group (n=10). The uterine lavage was performed 4 h before breeding in the pre-breeding group and 4 h after breeding in the post-breeding group. The oxytocin administration was performed twice in both treatment groups intravenously - immediately after and 12 h after the uterine lavage. A sterile NaCl solution (0.9%) was administrated intravenously in the control group.  In the control group there was a longer interval between parturition and first ovulation (14.6 days) compared to treatment groups (p<0.05). The pregnancy rates in the control; pre-breeding and post-breeding treatment groups were calculated as 40%, 40%, and 60%, respectively. Although early embryonic loss was not observed in both the pre- and post-breeding treatment groups, this ratio was 25%  for the control group. As a conclusion, the administration of a uterine lavage (1 liter of sterile 0.9% NaCl solution +4.000.000 IU crystallized penicillin +4g streptomycin sulfate) and 20 IU oxytocin 4 h before or after breeding mares at their first postpartum ovulation shortens the day interval between parturition and ovulation. It can be assumed that breeding during foal heat can be effective in reducing uterine involution, inflammatory reactions related to breeding and embryonic death.
