前言利用植物蛋白源部分或全部取代饲料中的鱼粉蛋白,是鱼类营养学家己经奋斗多年的目标。在已试验的所有植物蛋白源中,使用最广泛的是大豆粉。然而,不同的研究对鱼粉的取代程度不同,而且多数研究显示出生长减速及较低的饲料效率(Cowey等人,1971;Andrews和Page;1974;Cho等人,1974; Introduction The partial or complete replacement of fishmeal protein in feed with plant protein sources has long been the goal of fish nutritionists. Among all plant protein sources tested, the most widely used is soy flour.
