摘　　要：研究饲粮中添加不同水平的果寡糖和杆菌肽锌对24周龄广西黄羽肉鸡种鸡产蛋性能、血清生化指标和饲粮养分代谢率的影响。结果表明:与饲喂基础饲粮的对照组比较,基础饲粮添加0.2%、0.4%和0.6%的果寡糖组,广西黄羽肉鸡种鸡的产蛋率、蛋均重、蛋料比、种蛋合格率、合格种蛋受精率和孵化率提高;血清中胆固醇和甘油三酯含量降低,饲粮养分的表观代谢率提高。与基础饲粮添加0.05%的杆菌钛锌制剂组比较,添加果寡糖组效果具有优势。综合分析广西黄羽肉鸡种鸡饲粮中果寡糖添加水平以0.4%较为适宜。24 week-old Guangxi local yellow broiler breeder hens were selected to study the effects of dietary fructo-oligosac- charides（FOS） or antibiotics（bacitracin zinc）on laying performance, serum biochemical indices and dietary nutrient metaboliz- ability. The results showed that： compared with the control group, dietary FOS supplemented with 0.2 %,0.4 %,0.6% could increase the laying rate, average egg weight, feed egg ratio, eggs percent of pass, fertility rate and hatchability of qualified egg, and reduce serum levels of total cholesterol and triglyceride, and improve the apparent metabolizahility of dietary nutrients. The effects of diet supplemented with FOS was better than those of diet supplemented with 0.05%antibiotics. It was suggested that the appropriate additive amount of FOS in diets for yellow broiler breeder hens should be 0.4 %.
