摘 要:
试验选择1月龄左右的法国番鸭176只，随机分成A、B、C、D4组，每组设4个重复，每个重复11只鸭，A组饲喂由常规原料组成的颗粒料，作为对照组；B、C、D组分别饲喂含5％，10％和15％牛粪生物饲料的颗粒料，作为试验组。对试验数据进行统计学分析。结果表明：从总增重、饲料报酬和经济效益综合来看，c组与A组效果相当，而B、D两组低于A组，最适替代量为C组的10％。虽然在饲料中添加10％的牛粪生物饲料对鸭子生长性能影响不大，但扩大了饲料来源、降低了养殖成本，又可减少环境污柒。[著者文摘]

Abstract:
A total of 176 France muscory ducks at 1 -month old were randomly divided into 4 groups（A,B,C and D）,and each group had 4 replicates （11 ducks per replicate）. Grounp A was fed pellet formulated by general feedstuff（control） ;the treatment diet meals of gronps B, C and D were formulated by adding cattle dung biological feedstuff, 5%, 10% and 15%, respectively. Seen from total weight gain, feed efficiency and economic benefit, there were similar effection between group C and A, but the effection was higher for group A than groups B and D. It is best suitable that 10% cattle dung biological feedstuff was added in group C. Although 10% cattle dung biological feedstuff didn＇t have obvious influence on growth performance, the cattle dung biological feedstuff enlarged the resource of feedstuff, and it reduced the feeding cost. At the same time, it improved the environmental situation.[著者文摘]
