Abstract

A total of 250 Anak broiler chicks were used in a 28 days feeding trial in a completely randomized design, in a deep litter house to assess the effect of replacing feather meal (FEM) for fish meal (FM) on the performance of broiler chicks. Five replacement levels of the formulated feed: 0%, 2.5%, 5%, 7.5% and 10% of FEM were used for treatments 1, 2, 3, 4 and 5 respectively with 0% FEM as control. Treatments were replicated thrice. The broiler chicks were fed the experimental birds four weeks after one-week stabilization period. Feeding and water supply were ad libitum, while medication and vaccinations were appropriately applied. The deep litter house was provided with standard brooding facilities. Measurement of initial weights and final weights of birds were taken with a sensitive weighing balance (Salter brand) while mean daily weight gain, feed intake, feed conversion ratio and feed cost per kg gain were calculated. Results showed that final live weights 865.00g, 855.00g, 842.00g, 833.70g and 756.75g for birds fed 0%, 2.5%, 5.0%, 7.5% and 10.0% FEM respectively varied significantly (p were observed in daily feed intake, daily weight gain and feed cost/kg weight gain. Considering the results of final live weight and daily weight gain, it appeared that the 7.5% level of FEM is the optimal replacement level for FM. Keywords: Feather meal, fishmeal, poultry feed, broiler chick

饲粮用羽毛粉替代鱼粉对肉仔鸡生产性能的影响

选用250只阿纳克肉仔鸡，采用完全随机设计，在深窝鸡舍中进行28 d的饲养试验，研究用羽毛粉代替鱼粉对肉仔鸡生产性能的影响。试验1、2、3、4和5处理分别采用0%、2.5%、5%、7.5%和10%的FEM替代水平，对照组为0% FEM。治疗重复了三次。在1周稳定期后4周饲喂试验鸡。饲料和水的供应是自由的，而药物和疫苗的适当应用。深窝有标准的育雏设施。采用灵敏称重秤(索尔特牌)测量初重和末重，计算平均日增重、采食量、饲料系数和每公斤增重饲料成本。结果表明:饲粮中添加0%、2.5%、5.0%、7.5%和10.0% FEM的鸡的末活重分别为865.00g、855.00g、842.00g、833.70g和756.75g，日采食量、日增重和饲料成本/kg增重差异显著(p < 0.05)。综合最终活重和日增重结果，认为7.5%水平的FEM是饲料的最佳替代水平。关键词:羽毛粉，鱼粉，家禽饲料，肉鸡
