目的：研究落地枣替代玉米对蛋鸡生产性能的影响。方法：选取42周龄海兰褐蛋鸡300只，随机分为5个组，每组4个重复，每个重复15只。对照组饲喂基础日粮，试验组用落地枣分别替代基础日粮中3％、6％、9％、12％的玉米。预饲期7d，试验期8周。结果：结果表明：落地枣替代玉米提高了采食量、产蛋率、平均蛋重和产蛋量（P ＜0．05）。结论：落地枣替代玉米，能改善蛋鸡的生产性能，且替代12％的玉米效果最理想。%Objective:The experiment was conducted to study the effects of jujube powder instead of part of the corn on production performance of Laying hens.Method:A total of 300 Hyline Brown laying hens at 42 weeks old were random-ly divided into 5 groups with 4 replications of 1 5 each.The control group was fed with basal diets,and the testing groups were fed with basal diets with jujube powder replacement respectively 3%,6%,9%,1 2% of the corn.Pretest period was 7 days and experimental period was 8 weeks.Result:The results showed that the replacement of corn with landing jujube in the diet could improve feed intake,laying rate,average egg weight and egg production(P <0.05).Conclu-sion:The replacement of corn with landing jujube could improve production performance,and the effect was the best when replacing 1 2% corn(P <0.05).
