摘要
根据23周龄体重将300只“惠州麻”黄羽肉种鸡分为大、中、小3组,每组100只,统计其产蛋率、蛋重和种蛋合格率。结果表明;中等体重组在开产后产蛋率上升曲线更稳定,每只鸡所提供的可用种蛋数更多,小体重组的各项指标均表现不佳。
300 ＂Huizhou ma＂ natural breeders were divided into 3 groups based on weight in 23-week age： bigger, moderate and smaller. 100 hens are in each group. Egg producing rate, average egg weight and hatchable egg rate were noted and analyzed. The result showed that breeding value of moderate weight group was better than other groups and that of smaller weight group was worse than other groups.
