摘　　要：采用三羟甲基氨基甲烷、柠檬酸、糖类、卵黄和甘油稀释液制作绵羊细管冻精,公羊选用杜泊羊、无角陶赛特羊、特克塞尔羊、黑萨福克羊和白萨福克羊。结果表明,细管冻精解冻后活率以黑萨福克羊活率最高,与杜泊羊和特克塞尔羊相比差异显著(P<0.05),其它品种之间相比差异不显著(P>0.05)。后来发现绵羊冻精品质与其在当地的适应性有一定的相关性。Straw frozen semen of sheep was done in Tris （Hydroxymethyl aminomethane）, citric acid, glucide, yolk and glycerin diluent, and rams were chosen from White Dorper, Poil Dorset, Texel, White Suffolk and Black Suffolk. In consequence, The spermatozoa motilities of thawing semen of Black Suffolk was the best one, which had a significant difference with that of White Dorper and Texel （P〈0.05）. Other breeds had no significant difference with another. It was discovered afterward that qualities of straw frozen semen of sheep had some relativity with the adaptability under local environment.
