动物模型BLUP法评定内蒙古白绒山羊的遗传趋势

Estimated Genetic Trend for Inner Mongolia White Cashmere Goats Using Animal Model BLUP Method

本研究应用动物模型BLUP法估计了1989～1998年内蒙古鄂托克旗阿尔巴斯白绒山羊种羊场抓绒量和抓绒后体重的遗传进展。结果为抓绒量的遗传进展呈上升趋势，抓绒后体重的遗传进展基本平稳。研究表明，内蒙古白绒山羊根据个体表型值选种，存在准确性较差和难以同时兼顾两个性状的缺点。本文认为今后内蒙古白绒山羊选种方法应该采用动物模型BLUP法。

In this study,animal model BLUP method was used to estimate genetic trend for cashmere yield and bodyweight during 1989～ 1998 at Albas goats farm,Etuoke Banner,Inner Mongolia.The results were that genetic trend for cashmere yield had a rising trend and for bodyweight showed smooth.The study indicated selecting Inner Mongolia cashmere goats based on phenotypic value had a low accuracy and was difficult to give consideration to the two traits at the same time.The article raised animal model BLUP method should be used to select Inner Mongolia white cashmere goats in future.
