摘要
本试验旨在研究饲料中不同蛋白质和脂肪水平对黄姑鱼幼鱼生长性能、体组成成分和肠道消化酶活性的影响。试验配制9种不同蛋白质和脂肪水平饲料,其中蛋白质水平为:40%,47%和54%,脂肪水平为:5%,9%和13%。试验以11.76±0.20g的黄姑鱼为研究对象,进行为期8周的养殖试验。结果显示,投喂P54蛋白质组的鱼增重率和特定生长率显著高于投喂P40和P47蛋白质组;投喂L5脂肪组的鱼增重率和特定生长率显著低于投喂L9和L13脂肪组;鱼体脂肪含量随着脂肪水平的增加而显著升高;投喂P54蛋白质组肠道胰蛋白酶活力显著高于投喂P40和P47组,而投喂L13脂肪组肠道脂肪酶活力显著高于投喂L5和L9脂肪组。因此在本试验条件下,饲料蛋白质为54%,脂肪为13%时,也即蛋能比为26.2 mg kJ~(-1),黄姑鱼生长表现最好。
A feeding trial was conducted to determine the optimal dietary protein to lipid ratio for juvenile yellow drum Nibea albiflora(initial weight, 11.76± 0.20 g). Nine practical diets containing different protein(40%, 47%, or 54%) and lipid(5%, 9%, or 13%) levels were fed to triplicate groups for 8 weeks. The results showed that fish fed the P54 diet, regardless of dietary lipid level, had significantly higher weight gain(WG) and specific growth rate(SGR) than those fed the P40 and P47 diets. Fish fed L5 diet had significantly lower WG and SGR than those fed the L9 and L13 diets. Whole body crude lipid content increased significantly when dietary lipid level increased. Fish fed the P54 diet had significantly higher trypsin activity than those fed the P40 and P47 diets. Intestinal lipase activity of fish fed the L13 diet was significantly higher than that of fish fed the L5 and L9 diets. These results demonstrate that a diet containing 54% protein and 13% lipid with a P/E ratio of 26.2 mg protein kJ~(-1) is optimal for juvenile yellow drum.
