Effects of Ailanthus powder on the organismal non-specific immunity of Ctenopharyngodon idellus
The study was conducted to investigate the effects of different levels of Artemisia argyi powder on the or-ganismal non-specific immunity of grass carp(Ctenopharyngodon idella),and to determine the optimum amount of Artemisia argyi powder to be added to grass carp feed.In the experiment,400 grass carp weighing about 20g and in healthy condition were randomly divided into 4 treatment groups,with 4 replicates in each group and 25 fish in each replicate.The grass carp in the control group were fed a basal diet without ayahuasca,the grass carp in the test group A were fed a basal diet containing 2％ayahuasca,the grass carp in the test group B were fed a basal diet containing 4％ayahuasca,and the grass carp in the test group C were fed a basal diet containing 8％ayahuasca.After 60 d of feeding,the non-specific immunity indexes of the body of grass carp in each group were detected.The results showed that the serum lysozyme activity of grass carp in test group B and test group C was significantly increased(P＜0.05),the serum superoxide dismutase and glutathione peroxidase activity of grass carp in test group B and test group C was significantly increased(P＜0.05),and the serum malondialdehyde level of grass carp in all the aye-aye powder groups was significantly reduced(P＜0.05).The study showed that the addition of appropriate amount of Artemisia absinthium powder to grass carp feed could improve the non-specific immunity of the organ-ism,and the best effect was achieved with 4％of the addition.
