Abstract
The aim of this study was to determine the apparent digestibility coefficients and digestible values of crude protein, ethereal extract, gross energy and dry matter of mulberry leaf meal (MLM) (Morus alba L.) as Nile tilapia (Oreochromis niloticus) feed. A total of 135 Nile tilapia juveniles were used, and the indirect methodology (Cr2O3) was applied for digestibility determinations. Mulberry leave meal presented good apparent digestible coefficients of protein, ethereal extract and energy with respective values of 0.94, 0.58 and 0.39. The mulberry leave meal thus comprises adequate digestible protein and digestible energy values, similar or better than other leafy foods, presenting potential for inclusion in Nile tilapia diets.
本试验旨在测定桑叶粕(Morus alba L.)作为尼罗罗非鱼(Oreochromis niloticus)饲料的粗蛋白质、脂肪提取物、总能和干物质的表观消化率系数和消化值。利用135尾尼罗罗非鱼幼鱼，采用Cr2O3间接法测定其消化率。桑叶粕的蛋白质、脂肪和能量的表观消化系数分别为0.94、0.58和0.39。因此，桑叶粉含有足够的可消化蛋白质和可消化能量值，与其他叶类食物相似或更好，有可能被纳入尼罗罗非鱼的饮食中。
