Effects of allicin on the growth and non-specific immunity of Monopterus albus
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 S1,S2,S3 and S4,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 S3 and S4 of test groups were significantly higher than those of S1 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.
