摘要： 根据8周龄、20周龄体重将825只邵伯鸡母系母鸡分组,统计不同体重与初生蛋重、43周产蛋数之间的相互关系。结果表明:8周龄体重、20周龄体重与开产体重之间均呈极显著直线正相关(P<0.01),8周龄体重、20周龄体重与开产蛋重呈极显著的正相关(P<0.01),开产体重、开产蛋重与43周产蛋量之间呈极显著负相关(P<0.01)。母鸡43周产蛋数与20周体重之间呈极显著相关(P<0.01)。8周龄体重对43周产蛋数影响差异不显著,20周龄体重在1 300~1 600 g时,其43周产蛋数最高,可将20周龄体重作为邵伯鸡母系选种的重要参数之一。

Abstract: "825 Shaobo natural breed were divided based on weight at 8 week and 20 week age.Square eviation and correlation of eggs number at 43 weeks and average egg weight among different weight were analyzed.The results showed that correlation between 8 week and 20 week weight with first laying weight and average egg weight were in significant level(P0.01).The first laying weight and average egg weight were existed negative correlation with eggs number at 43 weeks(P0.01).The correlation between the 20 week laying weight and eggs number at 43 weeks was significant correlation(P0.01).No difference were found in different groups of 8 week age weight,1 300-1 600 g weight group was better than other groups in eggs number at 43 weeks.Therefore,the natural breed chicken of Shaobo can be early choosed based on weight of 20 week age.
