| 摘 要： | 以2%棉粕酶解蛋白肽(以下简称蛋白肽)分别等质量替代基础日粮中2%鱼粉和2%植物蛋白原料(1.0%豆粕+0.5%菜粕+0.5%棉粕),考察蛋白肽对(48.56±1.39)g建鲤(Cyprinus carpio var.Jian)生长性能、血清及肠道相关酶活的影响。结果表明:蛋白肽替代鱼粉或植物蛋白后试验组增重率和特定生长率均显著性高于对照组(P<0.05),同时饵料系数显著降低(P<0.05);蛋白肽可降低脏体比和肝体比,并显著性提高鱼体粗蛋白含量(P<0.05);同时可提高试验组建鲤血清溶菌酶、碱性磷酸酶和肠道中蛋白酶的活性。

| Abstract: | The experiment was conducted to investigate the effects of dietary protein resources replaced by cottonseed meal hydrolysate on growth performance,serum biochemical indices and intestinal digestive enzyme activities of Cyprinus carpio var.Jian(48.56±1.39) g.Fish were divided into 3 groups and fed with different diets.Group Ⅰ was fed with basal diet,group Ⅱ with the basal diet in which 2% fish meal was replaced by equivalent cottonseed meal hydrolysate,and group Ⅲ with the basal diet in which 2% plant protein resources(1%soybean meal+0.5%rapeseed meal+0.5% cottonseed meal) was replaced by equivalent cottonseed meal hydrolysate.The result showed that weight gain ratios and specific growth rates of group Ⅱ and Ⅲ were significantly higher than that of group Ⅰ(P<0.05).Feed conversion ratios of group Ⅱ and Ⅲ were significantly lower than that of group Ⅰ(P<0.05).Viscera somatic index and hepato somatic index of group Ⅱ and Ⅲ were lower than that of group Ⅰ.Protein contents of whole fish of group Ⅱ and Ⅲ were significantly higher than that of group Ⅰ(P<0.05).Activities of Lysozyme,Alkaline phosphatase in serum and protease in intestine of group Ⅱ and Ⅲ were higher than that of group Ⅰ. |
