摘要:
采用传统养殖试验方法进行了评价罗非鱼加工下脚料制备的2种产物替代秘鲁鱼粉在奥尼罗非鱼(Oreochromis niloticus×O. aureus)稚鱼实用日粮中的效果研究。实验设计了3种等蛋白质(33.8%)、等能量(16.50MJ/kg)左右的实用实验日粮, 对照组与试验组1、2日粮中分别添加秘鲁鱼粉、罗非鱼加工下脚料产物制备的酶解小肽和鱼粉。实验结果表明, 实验期间(63d)各实验组鱼均无死亡;添加罗非鱼鱼粉组鱼的特定生长率和饲料效益均显著性低于秘鲁鱼粉组(P < 0.05), 而添加罗非鱼酶解小肽组鱼的特定生长率和饲料效益均高于秘鲁鱼粉组, 但2组间无显著性差异(P > 0.05); 实验各组鱼的肝体比和肠脂比, 鱼体水分、粗蛋白质、粗脂肪、粗灰分、氨基酸比例与脂肪酸比例均无显著性差异(P > 0.05)。本实验认为, 在奥尼罗非鱼幼鱼罗非鱼实用日粮中罗非鱼酶解小肽可以替代秘鲁鱼粉, 但罗非鱼鱼粉养殖效果较秘鲁鱼粉差。

Abstract:
Evaluation of two produces from byproduct of tilapia as a replacement of Peru fish meal in practical diets of Juvenile Tilapia (Oreochromis niloticus×O. aureus) was studied with traditional aquaculture experiment. The three formulated practical diets were isonitrogenous (33.8%) and isoenergetic (l6.5MJ/kg) and Peru fish meal, enzymolysis small peptides and fish meal from byproduct oftilapia were added in control diet and test diet 1, 2 respectively. There were three replicate groups in each experimental diet group and there were 30 fish [initial weight (1.70 ± 0.03)g] in each replicate group. The experimental results showed that special growth ratio (SGR) and feed conversion ratio (FCR) did not differ significantly between fish fed Peru fish meal diet and fish fed small peptides from byproduct of tilapia diet (P > 0.05), but fish fed fish meal diet from byproduct of tilapia diet showed poorer SGR and FCR significantly than fish in above two groups during the experimental period (63d) (P < 0.05). No significant difference in carcass’s moisture, protein, lipid, ash contents, ratio of amino acids and fatty acids were found among fish fed the three diets (P > 0.05). Therefore, Results indicated that Peru fish meal in practical diets of juvenile Tilapia could be replaced by small peptides from byproduct of tilapia completely, but not by fish meal from byproduct of tilapia.
