To further raise the pregnancy rate of the sika and form integrated breeding technologies, the experiment analyzed the affecting factors on conception rate of sika. According to the degree of fatness, the sika were classified as superior, good, the bad. Their estrus rates were 93.8%, 75.0%, 4.4%, groups have significant difference （ P 〈 0.01 ）, heifer sika estrus rate was 38.2%, estrus rate of sika produced pups was 67.6 %, estrus rate of heifer sika to be cultivated was 55.9 %, there was quite differ- ent between sika produced pups and heifer sika in estrus rate. Conception rate of artificial insemination for male sika was 83.3 % between the former 1 h of female sika refusing to be climbed and 1 h after mount- ing, it was 51.9% in addition to this time, there were significant differences for conception rate between the two time （P 〈 0.01 ）. This study confirmed that degree of fatness, parturition stutus and insemination time were the main directly or indirectly affecting factors on conception rate of sika.%为进一步提高梅花鹿受胎率，并形成配套的繁育技术，本试验对影响梅花鹿受胎率因素进行分析。结果表明：优、良、差3种膘情的梅花鹿发情率分别为93．8％，75．0％，4．4％，差异极显著（P〈0．01）；育成梅花鹿发情率为38．2％，经产鹿发情率为67．6％，经过幼鹿培育的育成鹿发情率为55．9％，经产鹿与未经产鹿发情率存在较大差异；梅花鹿母鹿拒绝公鹿爬跨前后1h内输精的受胎率为83．3％，此外的输精受胎率51．9％，二者存在极显著差异（P〈0．01）。研究证实，膘情、经产与否、输精时间都是直接或间接影响梅花鹿受胎率的主要因素。
