摘  要：
为进一步提高梅花鹿人工输精受胎率,本试验对梅花鹿发情持续时间进行了观测,并进行了二次输精试验。结果表明,梅花鹿发情持续时间平均为18.35h±2.97h,范围是14h~25.53h,发情持续时间14h≤a<22h时段占90.32%,22h≤a<26h时段占9.68%;在梅花鹿发情持续期末进行1次冷冻解冻精液输精的受胎率为64.3%;在梅花鹿首次发情后12h进行第1次输精,第1次输精后4.5h~5h进行第2次输精,受胎率81.6%。2次输精较1次输精受胎率提高17.3%。根据梅花鹿发情持续时间分布规律,采取2次输精方法是提高梅花鹿受胎率的可行方法。

摘  要：
To further improving conception rate of artificial insemination in sika deer,this study investigated estrus duration and two times of repeat insemination method in sika deer. The results showed that estrus duration was 18. 35h ± 2. 97h,rang of variation was14h- 25. 53h,it was 90. 32% in the during of 14h≤a < 22h,it was 9. 68% in the during of 22h≤a < 26h,the estrous duration of sika deer mainly concentrated in the during of 14h≤a < 22h; Pregnancy rate was 81. 6% using two times of repeat insemination method,it was 64. 3% using once insemination method,and it was increased by 17. 3% comparing once insemination. This study has confirmed that if twice insemination method is to be adopted,it will be a feasible way to improve pregnancy rate according to the estrus duration distribution of sika deer.
