摘　　要：本文对影响羔羊断奶重的因素进行了分析,认为显著影响断奶重的主要因素有:胎次、哺乳期、初生重,单双羔等。按断奶重选留种羊的弊端是:(1) 双胎减少,繁殖率下降。(2) 延长了世代间隔。为此,需要通过改进繁殖技术和饲养管理来减少上述因素的影响。本文还介绍了不同性别,单双羔,胎次,哺乳期等不同因素的断奶重的校正方法。The main factors influcncing wcaning weight are as follows: brith times; suckling period; brith weight; single or twin et.Selection on weaning weight has following shortcominingcommig doenl ①Brecding performance; ② Needing more breeding time.
