摘要
为研究大蒜素对黄鳝生长和非特异性免疫的影响,以体重20.25±0.71 g的黄鳝为研究对象,将0(S_(1))、25(S_(2))、50(S_(3))和100(S_(4))mg/kg不同浓度的大蒜素添加到黄鳝基础饲料中,网箱饲养60 d,测定其生长性能和血清中的非特异性免疫指标。结果显示,随着大蒜素添加量的增加,试验组增重率和特定生长率均高于对照组,其中添加量为50和100 mg/kg时效果较好。随着时间的推移,试验组相关免疫酶活性与对照组的差异开始逐渐显现,饲喂时间越长,差异相对越明显;第60天,试验组S_(3)和S_(4)血清中的T-AOC、SOD、CAT和LSZ活性均明显高于S_(1)组(P<0.05)。这表明饲料中添加一定浓度的大蒜素可促进黄鳝生长,提高机体免疫力,以添加量在50~100 mg/kg为宜,为寻求新型、无毒害的黄鳝饲料添加剂提供参考。
In order to study the effects of allicin on the growth and non-specific immunity of Monopterus albus,with a weight of 20.25±0.71g was used as the research object,and different concentrations of allicin(0,25,50,and 100 mg/kg respectivly)were added to the Monopterus albus base feed(grouped as S_(1),S_(2),S_(3) and S_(4),respectivly),and fed in cages for 60 days.Growth performance and serum immune indexes were measured.The results showed that with the increase of allicin supplemental level,the weight gain rate and specific growth rate of experimental groups were higher than those of control group,and the supplementation of 50 and 100 mg/kg had the better effects.As time goes on,the difference of related immunoenzyme activity between the experimental groups and the control group began to gradually appear,and the longer the feeding time,the more obvious the difference was.On day 60,the activities of T-AOC,SOD,CAT and LSZ in serum of S_(3) and S_(4) of test groups were significantly higher than those of S_(1) group(P<0.05).These indicated that adding a certain concentration of allicin in the diet could promote the growth of Monopterus albus and improve the body immunity,and the appropriate dosage of 50 to 100 mg/kg.It provided theoretical references for seeking new and non-toxic feed additives for Monopterus albus.
