| 中文描述 | 牛的人工授精在動情期間的不適當時間點將會導致繁殖力下降並且重複生育.在配種前就已經排卵的母牛或是在配種後的那天仍保有濾泡,會使胚胎孕成率減少.對於狗來說,配種時間問題是導致狗胚胎發育失敗的主因.女性在動情周期間只育種一到兩次或者是太晚育種(在動情前期開始後14天)這些都是被列入懷疑的原因 |

| 英文描述 | Artificial insemination of cattle at the inappropriate time during estrus will lead to decreased fertility and repeat breeding. Cows which ovulated before insemination or still had a follicle on the day following insemination had decreased conception rates. Timing problems are a major cause of conception failures in dogs. Should be suspected in females bred only 1 or 2 times during the cycle or bred late (after day 14 from onset of proestrus). |
