摘要
在甘肃省肃南县康乐乡对甘肃高山细毛羊应用阴道栓与孕马血清促性腺激素(PMSG)结合处理,结果表明,不同注射剂量和处理方式对母羊的同期发情和繁殖率均有影响,在埋栓后12.5 d注射550 IU PMSG并在放栓后14 d撤除阴道栓后的0-48 h发情率显著高于其他试验组(P<0.05);在埋栓后13 d注射600 IU PMSG同时撤除阴道栓的试验组繁殖率最高(P<0.05)。但综合繁殖率和经济效益考虑,在埋栓后间隔12.5 d注射550 IU PMSG并在放栓后14 d撤除阴道栓0-48 h的试验组效果最好,平均每只母羊净收入可达773.7元。
In the present study,the rates of both estrus synchronization and reproduction of Gansu alpine-fine-wool ewes were investigated after CIDR（ Intravaginal Progesterone Insert） and PMSG（ Pregnant Mare Serum Gonadotropin） combination treatment in Kangle Town,Sunan County,Gansu Province. The ewes had the highest estrus rate（ P 〈0. 05） in 48 hours under treatment with 550 IU PMSG injection after 12. 5 days of using CIDRs and removing them in the 14 th day compared with other treatments. The ewes had the highest reproductive rate（ P〈 0. 05） under treatment with 600 IU PMSG injection after 13 days of using CIDRs and removing them at the same time. However,the former treatment was optimal if considering both reproductive rate and economic benefits which had 773. 7 CNY net income of per ewe.
