CIDR和PMSG诱导东北梅花鹿同期发情的初步研究

应用阴道内孕酮释放装置 (CIDR)结合不同来源和不同剂量的PMSG处理 ,观察东北梅花鹿同期发情效果。 2 6只试验鹿分成 5组 ,将CIDR放置母鹿阴道内 15d后取出 ,肌注不同剂量 (10 0～ 5 0 0IU)孕马血清促性腺激素 ,放入带试情布的公鹿试情 ,持续观察 72h。结果表明 ,取出CIDR后试验鹿在 (33.3± 7.0 )h发情。其中含 10 0IUPMSG的“Folligon”处理的试验鹿同期发情率达 10 0 % ;国产PMSG处理的梅花鹿随着PMSG剂量的增加 ,发情率有增加的趋势 ,但各组间差异不显著 (χ2 检验P >0 .0 5 )。同时 ,不同剂量的PMSG处理没有显著影响CIDR取出后至发情时的平均时间长度。

Estrus Synchronization of Dybowski Sika Doe ( C. N. Hortulorum) with CIDR and OMSG

Twenty six sika does, which were divided into 5 groups, were treated with CIDR ( controlled internal drug release device, containing progesterone) for 15 days and after removal of CIDR the animal were treated with different doses of PMSG (100 to 500 IU) to investigate the effect of the drugs on the estrus synchronization of does. A detecting stag with a peace of cloth hang under the abdomen to avoid successful mating was used to kept together with the experimental does for 72 hours to detect the state of estrus. Most does showed estrus 33.3±7.0 hours after the withdrawal of CIDR with a product Folligon, which contains 100IU PMSG having an estrus synchronization rate of 100%. Synchronization rate of does treated with domestic made PMSG increased slightly but not significantly as the doses increased (P> 0.05 ). There were no significant differences in the duration from the removal of CIDR to the time the does showing estrus between different treatments.
