为测定非洲鲇对饲料中色氨酸和精氨酸的需要量进行了70ｄ的投饵试验。使用的基本饲料以酪朊和凝胶为蛋白源并添加胱氨酸,饲料含蛋白质40%,含能量12ｋＪ/ｇ。平均体重115±11ｇ的非洲鲇鱼投喂含色氨酸3～13ｇ/ｋｇ的饲料,日饱食投喂2次。平均体重166±18ｇ的非洲鲇鱼投喂含精氨
A 70-day feeding trial was conducted to determine the levels of tryptophan and arginine in feedstuffs in African pomfret. The basic feed used was made of casein and gel as protein source and cystine was added. The feed contained 40% protein and energy 12kJ / g. The average body weight of 115 ± 11g of African anchovy feed containing tryptophan 3 ~ 13g / kg feed, feeding two times a day. An average of 166 ± 18g African anchovy feeding ammonia containing ammonia
