| 中文摘要: |
| 以初始平均体重为38.80±0.11 g的牙鲆Paralichthys olivaceus为实验对象，研究在高植物蛋白饲料中用低分子水解蛋白替代鱼粉对牙鲆生长、饲料利用及非特异性免疫指标的影响。分别以不同水解鱼蛋白替代总蛋白的0(FM1为负对照，含豆粕55%、鱼粉19%)、0(FM2为正对照，含豆粕45%、鱼粉25%）、11%(FPH11)、16%(FPH16)、21%(FPH21)、26%(FPH26)制得7组等氮等能饲料。实验结果表明，用低分子水解鱼蛋白替代总蛋白11%组的特定生长率显著高于负对照组（P<0.05），且与正对照组无显著性差异（P>0.05）；FPH11、FPH16、FPH21和FPH26组的摄食率显著高于负对照组（P<0.05）；替代总蛋白11%组的蛋白沉积率显著高于负对照组(P<0.05)，与正对照组相等（P>0.05）；替代水解蛋白各组的蛋白质消化率均显著性高于负对照组(P<0.05)，与正对照组无显著性差异（P>0.05）；替代水解蛋白各组的SOD活力都显著高于负对照组（P<0.05），且替代总蛋白11%组显著性高于正对照组；FPH6、FPH11、FPH16组的总抗氧化能力显著高于负对照组但显著低于正对照组（P<0.05）。 |
| 英文摘要: |
| A 63-day feeding experiment was conducted to evaluate the effects of fish protein hydrolysate as feed ingredient in high plant-protein diets on growth performance and non-specific immunity for Japanese flounder, Paralichthys olivaceus. Fish protein hydrolysates respectively replaced 0 (FM1, negative control， containing 55% soybean meal and 19% fish meal), 0(FM2，positive control， containing 45% soybean meal and 25% fish meal), 6% (FPH6), 11% (FPH11), 16% (FPH16), 21% (FPH21),and 26% (FPH26)of the total protein. The results showed that specific growth rate and protein retention of fish fed with FPH11 was significantly higher than FM1（P<0.05），but was not significantly different from FM2（P>0.05）. For protein digestibility, all the hydrolyzed protein diets were significantly higher than FM1（P<0.05），but was not significantly different from FM2（P>0.05）. Feeding rates of FPH11，FPH16，FPH21 and FPH26 were significantly higher than FM2（P<0.05）. The relative activities of acid phosphatase (ACP) in fish fed with FM1 was significantly lower than FPH26（P<005）. SOD relative activities in all the hydrolyzed protein diet were higher than FM1（P<0.05）, and SOD relative activities in FPH11 was significantly higher than FM2（P<0.05）. Total antioxidative capacity of FPH6, FPH11 and FPH16 were significantly higher than FM1 and lower than FM2（P<0.05）. |
