摘要: 经过60 d喂养,添加杂交狼尾草组的草鱼每尾平均日增重为(15.61±0.14)g,添加印度豇豆组的草鱼每尾平均日增重为(15.03 g±0.34 g).均比全配合饲料组(9.66 g±0.26 g)高,经方差分析差异极显著(P<0.01)。说明添加杂交狼尾草、印度豇豆对草鱼生长增重明显。另外,投喂杂交狼尾草、印度豇豆明显提高草鱼背部肌肉氨基酸水平,增加了鱼肉中人体必需氨基酸、呈味氨基酸的含量。Abstract: In a 60 d trail, the daily weight gain per fish in the group which were fed compound feed supplementing Pennisetum americanum?P.purpureum was 15.61?0.14 g, that in the group supplementing Vigna stnensis sari Var was 15.03?0.34 g,both of them were higher than that of CK (fed compound feed only, 9.66?0.26 g).Variance analysis showed there were significant differences (P0.01)between treatments and CK.It demonstrated that feeding Pennisetum americanum?P.purpureum and Vigna sinensis sari Var significantly improved the weight gain of grass carp.In addition, feeding forages increased the aminoacid level of back muscle of grass carp, enhanced the contents of human requisite aminoacids and taste aminoacids in the fish body.
