摘　　要：为探索梅花鹿(Cervus nippon)最佳同期发情方案,在吉林省双阳鹿业良种繁育有限公司挑选163只健康、发情周期正常、繁殖机能良好的供试母鹿随机分为3组:A组采用国产阴道孕酮栓(CIDR),B组采用进口CIDR,C组采用二次前列腺素(PG),均辅以孕马血清促性腺激素(PMSG)法处理。另挑选100只供试母鹿随机均分为4组,采用筛选出的较优方案结合不同剂量PMSG法处理(Ⅰ组100 IU、Ⅱ组300 IU、Ⅲ组500 IU、Ⅳ组700 IU),探析不同发情处理方案对梅花鹿母鹿发情效果、发情时间分布、受胎率和双胎率的影响以及不同PMSG剂量对母鹿发情受胎的影响。结果表明:A、B组同期发情率差异不显著,但A、B组同期发情率分别较C组高23.5%和33.3%(p<0.01),且A组掉栓率较B组高8.8%(p<0.05);3种处理方案对发情时间分布的影响极显著(p<0.01);B组与A、C组比较,受胎率和产仔率分别高6.5%和9.8%(p>0.05),双胎率分别高13.4%和17.6%(p>0.05);采用进口CIDR辅以不同剂量PMSG法对梅花鹿进行同期发情处理,发现Ⅱ组、Ⅲ组、Ⅳ组同期发情率较Ⅰ组分别高36.0%、40.0%和48.0%(p<0.05),呈随PMSG剂量升高而升高的趋势,其他各组间差异不显著(p>0.05),但发情时间均集中在24~48 h,Ⅰ组、Ⅱ组、Ⅲ组和Ⅳ组受胎率分别为46.2%、61.9%、59.1%和50.0%,呈先升高后下降的趋势(p>0.05)。综上所述,阴道埋栓的发情方案显著好于二次PG法,进口CIDR优于国产CIDR;进口CIDR+PMSG法的母鹿发情率和受胎率随PMSG剂量的增加而升高,但发情时间不受PMSG剂量的影响,PMSG适宜剂量为300 IU。In order to explore the optimal estrus synchronization plan for Cervus nippon,163 healthy,normal estrus cycle,and well reproducing female deer were selected from Shuangyang Deer Industry Breeding Co.,Ltd.in Jilin Province and randomly divided into three groups:Group A was treated with domestic vaginal progesterone suppositories(CIDR),Group B was treated with imported CIDR,and Group C was treated with secondary PG supplemented with pregnant horse serum gonadotropin(PMSG).Another 100 female deer were randomly divided into four groups,and the selected optimal plan was combined with different doses of PMSG treatment(100 IU in Group Ⅰ,300 IU in Group Ⅱ,500 IU in Group Ⅲ,and 700 IU in Group Ⅳ),to explore the effects of different estrus treatment plans on the estrus effect,estrus time distribution,conception rate,and twin lambing rate of C.nippon,as well as the effects of different PMSG doses on the estrus conception of female deer.The results showed that there was no significant difference in the synchronous estrus rate between Group A and Group B,but the synchronous estrus rate in Group A and Group B was 23.5% and 33.3% higher than those in Group C,respectively(p<0.01),and the thrombus shedding rate in Group A was 8.8% higher than that in Group B(p<0.05).The three treatment schemes had a significant impact on the distribution of estrus time(p<0.01).Compared with Groups A and C,the fertility rate and farrowing rate in Group B wer higher than those in Groups A and C,respectively 6.5%and 9.8%(p>0.05),the twin rate is higher than 13.4% and 17.6%(p>0.05).Adopting imported CIDR combined with different doses of PMSG for synchronous estrus treatment of C.nippon revealed that the estrus rate in the Groups Ⅱ,Ⅲ,and Ⅳ was 36.0%,40.0%,and 48.0% higher than that in Group Ⅰ(p<0.05),showing an increasing trend with the increase of PMSG dose.There was no significant difference between the other Groups(p>0.05),but the estrus time was concentrated between 24-48 hours.The conception rates of GroupsⅠ,Ⅱ,Ⅲ and Ⅳ were
