摘要:

为探讨饲料蛋白质水平对杂交黄颡鱼(黄颡鱼♀×瓦氏黄颡鱼♂)生长、消化酶活性和抗氧化能力的影响,制备蛋白质水平分别为30%、35%、40%、45%和50%的5种试验饲料并用其喂养(1.00 ± 0.05)g杂交黄颡鱼,投喂试验时间为60 d,以确定杂交黄颡鱼饲料蛋白质的最适添加水平。结果表明:1)当饲料蛋白质水平为40%~45%时,杂交黄颡鱼生长性能最佳,杂交黄颡鱼的增重率、特定生长率等生长指标均显著提高(P<0.05)。2)饲料蛋白质水平40%组的杂交黄颡鱼的胃和肠道蛋白酶活性最高(P<0.05),饲料蛋白质水平45%组的淀粉酶和脂肪酶活性最高(P<0.05);各组胃蛋白酶活性均高于肠道,肠道淀粉酶、脂肪酶活性在饲料蛋白质水平≥40%时高于胃。3)饲料蛋白质水平为40%~45%组的杂交黄颡鱼肝脏超氧化物歧化酶(SOD)和谷胱甘肽过氧化物酶(GPX)活性显著高于其他组(P<0.05);当饲料蛋白质水平≥40%时,过氧化氢酶(CAT)活性较高(P<0.05);丙二醛(MDA)含量随饲料蛋白质水平的增加呈先下降后上升的趋势。综上所述,(1.00 ± 0.05)g杂交黄颡鱼饲料中蛋白质的最适添加水平为40%~45%。

Abstract:

The study was conducted to explore the effects of dietary protein levels on growth,digestive enzymes activities and antioxidant ability of hybrid yellow catfish (Pelteobagrus fulvidraco♀×P.vachelli♂).Five experimental diets were formulated containing dietary protein 30%,35%,40%,45% and 50%,respectively.Hybrid yellow catfish [(1.00±0.05)g] were fed with five experimental diets for 60 days.The objective of this experiment was to determine the dietary protein requirement of hybrid yellow catfish.The results indicated that the dietary protein level was 40%-45%,the growth performance of hybrid yellow catfish was the best,and the final weight,specific growth rate (SGR) were increased significantly (P<0.05).The activity of protease in stomach and intestine in 40% protein group was the highest,the activity of lipase and amylase in 45% protein group was the highest.In all groups,the activity of protease in stomach was higher than that of intestine.The activities of lipase and amylase in intestine were higher than that of stomach when the dietary protein level exceeded 40% (including 40%).The activities of superoxide dismutase (SOD) and glutathione peroxidase (GPX) in the liver of hybrid yellow catfish were significantly higher than that of other groups (P<0.05) when the dietary protein level was 40%-45%.The catalase (CAT) activities were higher than those of other groups when the dietary protein level exceeded 40% (including 40%).The content of malonaldehyde (MDA) decreased and then increased with the increase of dietary protein level.In conclusion,the optimal dietary protein level of hybrid yellow catfish [(1.00±0.05)g] was 40%-45%.
