摘　　要：选用273日龄健康的父母代罗曼褐种蛋鸡2800只,随机分成5组,Ⅰ组为对照组,Ⅱ、Ⅲ、Ⅳ、Ⅴ组为试验组。试验期为7周,其中,预饲期1周,试验期6周。在Ⅱ、Ⅲ、Ⅳ、Ⅴ试验组的基础日粮中分别添加益康XP制剂0.15%﹑0.25%﹑0.3%﹑0.5%,对照组Ⅰ组饲喂基础日粮。结果表明,在基础日粮中添加0.3%的益康XP制剂,可使蛋种鸡产蛋率提高,采食量下降。A total of 2 800 273-day-old healthy parental brown Roman breeding layers were randomly divided into five groups. The group Ⅰ was the control group, and the groups Ⅱ,Ⅲ, Ⅳ, and Ⅴ were the experimental groups. The trial last for seven weeks, one week of which was pre-feeding period and six weeks of which was experimental period. The Yikang XP was added to the diet of the experimental groups （ Ⅱ,Ⅲ,Ⅳ, and Ⅴ） at the ratio of 0.15 %, 0.25 %, 0.3 %, and 0.5 %, respectively. And the chickens of group I were fed with the basal diet. The results showed that the addition of Yikang XP at the ratio of 0.3 % promoted the laying rate of breeding layers and reduced feed intake.
