| 摘 要： | 本实验旨在探究饲料中添加海洋性动物水解蛋白对珍珠龙胆石斑鱼（Epinephelus fuscoguttatus ♀ × Epinephelus lanceolatus ♂）幼鱼（9.6 + 0.01g）生长、饲料利用的影响。以60%鱼粉组为正对照组（positive control，PC），40%鱼粉组为负对照组（negative control，NC）。其余5组在NC组基础上分别添加CAA（晶体氨基酸）、10%鱼溶浆（fish soluble，FS）、10%酶解虾膏（shrimp paste，SP）、10%鱿鱼膏 （squid paste，SUP）和12%上述混合水解蛋白（mixture，MIX）（鱼溶浆：酶解虾膏：鱿鱼膏为1:1:1）。结果表明，NC组和CAA组的特定生长率相较PC组显著下降，而在低鱼粉饲料中添加海洋性蛋白源明显提高了石斑鱼的生长性能，使其与PC组没有显著性差异。NC组的饲料效率最低，显著低于其余各组，且其余各组间均无显著差异，其中以SP组最高。蛋白质效率和饲料效率与摄食率呈现出一致的变化趋势。综上，三种海洋性蛋白源在促摄食及生长上具有相当的效果， 在低鱼粉（40%）饲料中添加海洋性水解动物蛋白能显著促进鱼体生长且与正对照无显著性差异。这意味着海洋性动物水解蛋白的添加可明显提高石斑鱼低鱼粉饲料的营养价值。

| Abstract: | The present study was used to investigate the role of marine animal protein hydrolysates inclusion on the growth and feed utilization of hybrid grouper. The diet with 60% and 40% fish meal were considered as the positive control (PC) and negative control (NC), respectively. Another five diets were formulated with the supplementation of crystal amino acid (CAA), fish soluble (FS), shrimp paste (SP), squid paste (SUP) or their mixture (MIX). Results showed that the specific growth rate of grouper was significantly reduced in the NC and CAA groups compared to the PC group. However, the supplementation of marine animal protein hydrolysates significantly improved the negative effect on SGR induced by high fishmeal replacement. The fish in the NC group obtained the lowest feed intake (FI), while no significant difference was observed in other treatments. The feed efficiency rate (FER) and protein efficiency rate (PER) followed the similar pattern with that of FI. In above, the three marine protein sources have considerable effects in promoting feeding and growth, the inclusion of marine animal protein hydrolysates in low fish meal based diets can significantly improve the growth and feed utilization of hybrid grouper, which was not significant with the PC. The above result indicated that the supplementation of marine animal protein hydrolysates improve the nutrition value of low fish meal based diets. |
