摘　　要：试验旨在探讨复合微生态制剂对产蛋高峰期蛋鸡生产性能的影响。将40周龄的海兰褐蛋鸡380只随机分为2组,对照组饲喂基础日粮,试验组在基础日粮中添加复合微生态制剂,添加量为0.1%,预饲期1周,试验期3周。结果表明,复合微生态制剂对40周龄蛋鸡的日产蛋重、平均蛋重、产蛋率和鸡蛋破损率均无显著影响(P>0.05),但可以显著降低蛋鸡的采食量与料蛋比(P<0.05),提高经济效益。To find the effect of compound microecological on production performance of layers, 380 40-weeksold Hyline Brown layers were randomly divided into two groups, control group was fed with basic diet and experimental group added 0.1% compound microecological preparation. All layers were pre-feed for 1 week and formal experiment period was 21 days. The results showed that probiotics had no significant effect, on average egg weight, egg laying rate and damage rate（P0.05）, but could significantly reduce the feed intake and feed egg ratio. Probiotics could significantly increase the economic efficiency.
