黄鳝的营养素需要量及饲料最适能量蛋白比

Requirements of nutrients and optimum energy protein ratio in the diet for Monopterus albus

用正交设计法L9(34 )配制九种试验饲料 ,对黄鳝配合饲料中蛋白质、脂肪、总能、无机盐需要量及最适能量蛋白比进行了研究 ,结果表明 ,影响黄鳝生长的主要因素是蛋白质和总能 ,黄鳝最佳生长所需饲料中蛋白质含量为 35 .7% ,总能为 1 1 .5 0～ 1 2 .5 0kJ·g-1饲料 ,脂肪含量 3%～ 4% ,无机盐含量 3% ,总糖 2 4%～ 33%。黄鳝饲料的最适能量蛋白比 (E/P =kJ·g-1)为 31 .6～ 38.

The L 9(3 4)table of orthogonal design method was used to formulate nine diet combinations,which were employed to determine the requirements of protein,fat,mineral and general energy for eel, Monopterus albus. The results indicated that protein and general energy were the major elements that affected the growth of Monopterus albus. The optimum percentage of protein,fat,mineral and carbohydrate were 35.7%,3%-4%,3% and 24%-33% respectively. In the diet of Monopterus albus, the relative general energy and energy protein ratio(E/P=kJ·g -1 ) were 11.50-12.50 kJ·g -1 and 31.6-38.9 respectively.
