辣木叶粉在鱼饲料中的应用研究

目的]辣木是一种尚未充分开发利用的树种。辣木绿色物质部分产量高,营养丰富,开发其资源可弥补传统蛋白质饲料源的短缺。探讨以辣木叶粉作为配方主要蛋白质原料之一和组成全价颗粒鱼饲料配方的可行性。方法]以15%的辣木叶粉替代8.7%的次粉和6.3%的菜籽粕构成全价颗粒饲料配方,研究辣木叶粉对鱼生长和饲料利用的影响。结果]试验组罗非鱼平均鱼体终重和平均增重均比对照组明显提高,而饲料系数则比对照组显著降低。试验组鱼存活率比对照组略低。结论]该研究可为水产动物营养研究和进一步研制高效、廉价的温水性鱼人工配合饲料提供基础资料。

Application Effects of Moringa Leaf Powder in Fish Feed

Objective] Moringa is an underutilized tree species. Developing of＇Moringa＇could make up for the shortage of traditional protein feed source for its high yield and abundant nutrition. The possibility of Moringa leaf powder as one of the main protein sources was discussed. Method] We used Moringa leaf powder （ 15% ） complete formula feed to intake the feed made from wheat middlings （8.7%） and rapeseed meal （6.3%）. Result] To compare test group with control group, the average weight, final weight, and average weight gain of test group were increased obviously while feed coefficient was decreased obviously. However, viability of test group was slightly lower than control group. Conclusion] The study can provide basic data for aquatic animal nutrition research and high -efficient, cheap artificial fish feed.
