摘要
对713只雅安奶山羊、728只成都麻羊、366只简阳大耳羊、334只南江黄羊母羊受体分别分成3组,按3种炔诺酮阴道栓-FSH程序进行同期发情处理。研究结果表明,3种同期发情处理程序对不同品种母羊都有较好的同期发情效果,4个品种的同期发情有效率分别为92 3%(658/713)、92 7%(675/728)、91 7%(336/366)和90 4%(302/334),发情羊排卵并形成功能黄体的比率分别为71 0%(467/658)、67 1(453/675)、69 9(235/336)和63 9(193/302)。4个品种母羊从撤除炔诺酮阴道栓到发情的间隔时间分别为43 3±14 3、47 0±20 5、42 8±13 0、50 8±19 4h,发情持续时间分别为44 8±14 9、43 8±19 3、39 8±13 4、40 8±19 1h。
The synchronized estrus were induced by three kinds of methods for 713 Ya'an Milk Goats,728 Chengdu Ma Goat,366 Jianyang Big-ear goat and 334 Nanjiang Yellow Goat.The results showed that the percentages of synchronized estrus in four breed goats were 92.3 %(658/?713),92.7 %(675/?728),91.7 %(336/?366)and 90.4 %(302/?334),respectively,the percentages of estrus recipients with corpus luteum on their ovary were 71.0 %(467/?658),67.1 %(453/?675),69.9 %(235/?336)and 63.9 %(193/?302),respectively,the time separations from removed norestrel-impregnated intravaginal sponges to onset of estrus were 43.3±14.3,47.0±20.5,42.8±13.0,50.8±19.4 h,respectively,the duration of estrus were 44.8±14.9,43.8±19.3,39.8±13.4,40.8±19.1 h,respectively.
