摘　　要：为研究添加不同水平三丁酸甘油酯对胡子鲶生长及肝功能指标的影响,试验选取初始平均体重为5.26 g的胡子鲶,分为对照组和试验组共4个处理组,每个处理组4个重复,每个重复200尾鱼。在基础日粮中分别添加三丁酸甘油酯0、0.05%、0.075%和0.1%,配制成4种试验饲料。结果表明:①三丁酸甘油酯0.05%和0.075%添加组,试验末重、特定生长率显著高于对照组,饵料系数显著低于对照组(P<0.05);对照组和0.1%添加组,试验末重、特定生长率和饵料系数均为差异不显著(P>0.05);三丁酸甘油酯0.05%、0.075%和0.1%添加组,成活率显著高于对照组(P<0.05),三丁酸甘油酯0.05%、0.075%和0.1%添加组,三组间成活率差异不显著(P>0.05);②三丁酸甘油酯0.05%、0.075%和0.1%添加组肥满度、脏体指数和肝体指数显著高于对照组(P<0.05);三丁酸甘油酯添加量达到0.05%以后,三个处理间肥满度、脏体指数和肝体指数无显著变化(P>0.05);③试验组与对照组血清AST、ALT活性分别小于肝胰脏AST、ALT活性,表明鱼体的肝胰脏功能正常,肝胰脏细胞没有受到明显的损伤;各试验组肝胰脏中的AST和ALT与对照组相比均无显著性差异,试验组血清中AST和ALT活性显著低于对照组(P<0.05);三丁酸甘油酯0.05%、0.075%和0.1%添加组三组间血清中AST和ALT活性差异不显著(P>0.05)。添加0.05%的三丁酸甘油酯不仅能提高胡子鲶增重、特定生长率、成活率,以及鱼体肥满度,降低饵料系数,而且不会对肝胰脏造成负担,还能降低血清中转氨酶活性,提高脏体指数和肝体指数。To study the effects of different levels of tributyrin on growth and liver function indexes of Clarias fuscus.In this study,Clarias fuscus with an initial average weight of 5.26 g were selected and di⁃vided into four treatment groups,namely the control group and the test group.Each treatment group had four replicates with 200 fish per replicate.Four types of experimental feeds were made by adding 0%,0.05%,0.075%and 0.1%tributyrin into the basic diet.The results showed that:①The final weight and specific growth rate of the triglyceride 0.05%and 0.075%added groups were significantly higher than those of the control group(P<0.05).The feed conversion ratio of the triglyceride 0.05%and 0.075%add⁃ed groups were significantly lower than those of the control group(P<0.05).There were no significant differences in the final weight,specific growth rate and feed conversion ratio between the control group and the 0.1%addition group(P>0.05).The survival rates of three test groups were significantly higher than that of the control group(P<0.05).The sur⁃vival rate among the three test groups was not sig⁃nificantly different from each other(P>0.05).②Fatness,visceral indexes,and liver function in⁃dexes were significantly higher of tributyrin added groups(0.05%,0.075%,and 0.1%)than the control group(P<0.05).After the addition of tributyrin reached 0.05%,there were no significant differences in the fatness,viscera indexes,and liver body indexes among the three treatments(P>0.05).③The serum GOT and GPT activity of the test groups and the control group was lower than that of the liver and pancreas GOT and GPT activity,indicating that the liv⁃er and pancreas function of the fish body was normal,and liver and pancreas cells were not significantly damaged.Compared with the control group,GOT and GPT in the liver and pancreas of each test groups showed no significant difference.The serum activity of GOT and GPT in the test groups was significantly lower than that in the control group(P<0.05).There was no significant diffe
