摘　　要：以中原地区养殖量比较大的三花鹅为研究对象,研究不同开产体重对种鹅生产性能的影响。根据体重将母鹅分为三个试验组(Ⅰ组、Ⅱ组、Ⅲ组),开产前三个试验组母鹅的体重分别为3.4、3.9、4.4 kg,每组1500只,6个重复,公母配比均为1∶4。开始产蛋后统计种鹅生产性能指标。种鹅的蛋重与开产体重呈正相关,开产体重与开产日龄呈负相关。产蛋前期,试验Ⅰ组的蛋重和产蛋率小于其他两组(P<0.05),试验Ⅰ组和试验Ⅱ组的种蛋受精率高于试验Ⅲ组(P<0.05);产蛋中期,试验Ⅱ组和试验Ⅲ组的蛋重和产蛋率高于试验Ⅰ组(P<0.05);产蛋高峰期,试验Ⅱ组的种蛋受精率高于试验Ⅲ组(P<0.05)。三花鹅适宜开产体重为3.9 kg。Taking Sanhua geese with large breeding amount in Central Plains as the research object,the effects of different starting weight on the production performance of breeding geese were studied.According to the weight,the female geese were divided into three experimental groups(group I,group II and group III).The weight before laying was 3.4,3.9 and 4.4 kg respectively,with 1500 geese in each group and 6 repetitions.The male female ratio was 1∶4.The production performance indexes of breeding geese were counted after laying eggs.The egg weight of breeding geese was positively correlated with the start weight,and the start weight was inversely correlated with the age of the start date.In the early stage of egg laying,the egg weight and egg laying rate of test groupⅠwere lower than those of the other two groups(P<0.05),and the fertilization rate of breeding eggs in test group I and test groupⅡwas higher than that in test groupⅢ(P<0.05);In the middle of egg laying,the egg weight and egg laying rate of test groupⅡand test groupⅢwere higher than those of test groupⅠ(P<0.05);At the peak of egg production,the fertilization rate of breeding eggs in groupⅡwas higher than that in groupⅢ(P<0.05).The suitable opering weight of Sanhua goose was 3.9 kg.
