Effect of allicin on non-specific immunity of common carp
The purpose of this study is to investigate the effect of different levels of allicin on the nonspecific immunity of carp and determine the optimal addition level of allicin in carp production.For trials,480 healthy carp weighing approximately 20g were selected,which were equally divided into 4 groups with four replicates ac-cording to the univariate trial design principle and 30 carp each.The test carp in each group were fed with the test diet supplemented with 0,0.5％,1％and 2％allicin.Test carp were domesticated for 7d,and the formal test period was 56d.The end of the test tested the non-specific serum immunity of each group.The results showed that feed-ing 1％and 2％allicin could significantly improve the viability of superoxide dismutase,lysozyme and catalase(P＜0.05),and significantly reduced the level of malondialdehyde(P＜0.05).Studies have shown that the appropriate amount of allicin can improve the non-specific immunity of the carp body,and the optimal amount of allicin is 1％.
