摘　　要：在 5 ,8 ,1 0三个不同月份 ,用含 1 8-甲基 -炔诺酮 5 0 mg的实用型阴道海绵栓处理 6 31只陕南白山羊进行同期发情 ,撤栓时注射 FSH,阴道栓处理时间分为短期处理(9,1 0 ,1 1 ,1 2 d)和长期处理 (1 5 ,1 6 ,1 7d)。结果表明 ,短期和长期处理之间 ,以及不同月份之间 ,受试羊发情开始距撤栓的平均间隔时间和同期发情有效率差异不显著 (P>0 .0 5 )。结论认为 ,用实用型炔诺酮阴道栓进行陕南白山羊同期发情处理时 ,可选用短期处理法 ;只要避开高热及严寒 ,其它季节均可进行同期发情处理。In May,Augus and October, estrus synchronization were induced by using of 50mg Norgestrel-impregnated Intravaginal Sponge treatment with injections of FSH at sponges removal, and with shorter(9,10,11,12 d) or longer(15,16,17 d) implanting periods in 631 Shannan White Goats. Results show that the time separation from sponges were removed to onset of oestrus and effective rates of estrus synchronization were similar between varying implanting periods or varying months. The conclusion were that shorter implant...
