摘要
本文应用1982年家畜品种资源和田羊生产性能调查数据为对照组,以近年对和田羊生产性能测定数据为实验组,通过20年间和田羊主要生产性能前后变化,做出分析和研究,从中探索出和田羊生产性能变化的相关性及其规律,掌握和田羊羊毛品质、体重、产毛量等主要生产性能的遗传性、风土驯化的主要原因,为和田羊本品种选育和基因库保护探索行之有效的育种、管理机制。
Twenty years of investigation data about Hetian sheep production performance has been analyzed, using the data of 1982 as control group. By contrasting and analyzing, we explore the pertinency and changing rule of Hetian sheep production performance as well as the genetic rule of some main production performance factors such as sheep wool quality, weight, and wool yield, which will provide support to breeding and gene protection.
