摘　　要：对两批18周龄体重分别仅有1013和1021克,均匀度55.1和58.8％的京白823商品代母鸡,采取加强防疫、提高营养水平,减少各种应激等项综合性饲养管理措施。结果5760只入舍母鸡的72周龄入舍鸡和饲养日产蛋量分别达到268.75和276.85枚/只,全程平均蛋重为58.33克/枚, 21～72周龄耗料量为41.21。公斤/只,存活率为85.56％。说明均匀度差,体重轻的鸡,通过合理的饲养管理,可以取得理想的生产成绩。同时也说明北京白鸡有着很大的生产潜力。In this paper, there were two groups of commercial Beijing White Leghorn laying hens, which standard body weight and uniformity at 18-oid-week were 1310g and at least 75%respctiveiy, but actual corresponding data were 1013g, 55.1% and 1021g, 58.8% to group 1 and 2.The comprehensive measures were focused on strengthening disease prevention, increasing levels of nutrients, decreasing various stresses and so on during the laying period. The results of 5760 housed hens showed that the hen-housed and the hen-day egg production were 258.75 and 276.85/hen resp, the egg weigt, the feed consumptgon and the viability Were 58.33g/egg, 41.21Kg/hen and 35.56% resp. from 21 to 72-old-week.
