摘要

本實驗目的為探討利用雞肉粉取代飼料中之魚粉蛋白對點帶石斑成長的影響。實驗飼料分別以雞肉粉取代0、15、30、45、60和75%的魚粉蛋白，並調整為等蛋白（45%）、等油脂（12%）之六組飼料。實驗魚體平均初重為4.54 g，實驗進行五週，每日投餵三次，餵至飽食。實驗結果指出，點帶石斑魚餵食飼料含雞肉粉取代15、30、45和60%的魚粉蛋白與控制組無顯著差異的增重率及SGR，且顯著高於點帶石斑魚餵食飼料含雞肉粉取代75%魚粉蛋白組。點帶石斑餵食含雞肉粉組飼料的肌肉組織比控制組含較高的灰分，較低的油脂與粗蛋白質。本實驗結果指出飼料中雞肉粉可取代至60%魚粉蛋白而不影響點帶石斑的成長。

This study was conducted to investigate the effects of partial fish meal protein replaced by poultry byproduct meal protein on orange-spotted grouper ＂Epinephelus coioides＂. Six isonitrogenous (45% crude protein) and isolipidic (12% crude lipid) diets were formulated to contain 0, 15, 30, 45, 60 and 75% fish meal protein replaced by poultry by-product meal protein. 4.54 g juvenile orange-spotted grouper were fed with treatment diets three times a day until satiation for five weeks feeding trial. Weight gain and specific growth rate (SGR) of grouper fed diet with 15, 30, 45 and 60% replacement of fish meal protein by poultry by-product meal were not significantly different from those of fish fed the control diet. However, the growth performance of grouper fed diet containing 60% fish meal protein replaced by poultry by-product meal protein was significantly higher than that of grouper fed diet with 75% replacement of fish meal protein by poultry by-product meal protein. Muscle proximate of grouper fed poultry by-product meal groups had higher ash, and lower crude protein and crude lipid contents than those of grouper fed the control diet. In conclusion, poultry by-product meal could replace up to 60% of fish meal protein in the diet for orange-spotted grouper ＂E. coioides＂.
