为探讨不同添加剂对蛋鸡生产性能的影响，选用1500只280日龄海兰褐蛋鸡，随机分为5组，每组5个重复，每个重复60只；对照组饲喂基础日粮，基础日粮中分别添加0.015％土霉素、0.01％微生态制剂、0.1％中草药提取物和5％新型生物复合预混剂为试验Ⅰ-Ⅳ组，研究几种添加剂对海兰褐蛋鸡生产性能和蛋品质指标的影响，试验期30 d。结果表明：基础日粮中添加微生态制剂、中草药提取物和新型生物复合预混剂，其蛋鸡产蛋性能和蛋白质均优于对照组和添加土霉素组，且以添加5％新型生物复合预混剂组蛋鸡生产性能更佳。

The objective of this study was to approach the effect of different additives on performance of laying hens . One thousand five hundred 280-day-old healthy Hyline laying hens were randomly divided to five treatments with five replicates for each and sixty hens in each replicate .The control group was fed with the corn-soybean meal based diet , and the treated groups were added by 0.015% hydroxytetracline , 0.01% microeco-preparation , 0.1% Chinese herbal medicine extractive , and 5%biologic complex mixture on the basis of the control group respectively .We in-vestigated the effect of different additives on performance and egg quality of laying hens for 30 days.The results showed that the groups added with microecologics , Chinese herbal medicine , and complex mixture significantly in-creased egg quantity and egg weight , improved the contents of cholesterin , ash, protein and the egg thickness .The results indicated that basal diet added by5 %biologic complex mixture can increase the performance of laying hens and showed a better egg quality .
