摘  要:
人工授精技术的关键是母鹿的发情鉴定。半散放母鹿的发情表现分为 3种类型 :隐性发情、表现发情和发情 ,表现类型不同 ,受孕率也不同。发情母鹿的受孕率为 95 0 0 % ;表现发情母鹿的受孕率为 71 43 % ,隐性发情母鹿的受孕率为 5 0 0 0 %。人工授精输精率为 85 5 8% ,受孕率为 78 65 %。同自然繁殖的母鹿相比 ,受孕率提高近 3 0 %。

摘  要:
The key technique of artificial insemination(AI)for animals is oestrus diagnosis The estrus expression of the female deer in the semi grazing condition could be classified in to three categories as follows: recessive estrus13 46%, phenotypic estrus 33 65%, and estrus 38 46%, Pregnancy rates of the animals are different if their estrus expressions are not the same In the experiment group of AI, the pregnancy rate of the normal estrus female deers is 95 00%,however,the rates of the phenotypic and recessive estrus animals are 71 43% and 50 00%,respectively The AI rate of the animals is 85 58% Total pregnancy rate of AI in the animals is 78 65%,30% higher than that of natural service in the female deer
