集中采精、分散输精技术在玉树安哥拉山羊改良中的应用效果
CHINESE QINGHAI JOURNAL OF ANIMAL AND VETERINARY SCIENCES(2000)
Abstract
采用经过改良的精液稀释液配方和集中采精、高倍稀释、常温保存、分散输精、倒立法配种技术,用安哥拉山羊种羊对玉树当地土种山羊进行人工受精配种试验,1个情期和1.5个情期受胎率分别达到71%和84%.安哥拉山羊自然本交改良受胎率为64%,当地土种山羊繁殖率为68.41%.试验证明,在当前牲畜折价归户、草场承包到户后羊群无法大群集中的现实条件下,该技术是开展绵山羊改良工作简便易行、群众欢迎的人工受精方法之一.
