Effects of compound acidifiers on growth performance,nonspecific immunity,and serum biochemical indexes of grass carp
摘要
Abstract
The purpose of this experiment was to study the effects of different levels of compound acidifiers on the growth performance,nonspecific immunity,and serum biochemical indexes of grass carp.A total of 480 grass carps with similar weight were randomly divided into four groups with three replicates in each group and 40 grass carps in each replicate.Grass carp in the control group were fed with basic feed,while grass carp in the experimental group were fed with feed containing 0.1％(0.1％compound acidifier group),0.2％(0.2％compound acidifier group)and 0.4％(0.4％compound acidifier group),respectively.The trial period was eight weeks.The results showed that compared with the control group,the powder weight,weight gain rate and specific growth rate of grass carp in the 0.2％compound acidifier group increased significantly(P＜0.05),while the feed coefficient decreased significantly(P＜0.05).The liver-body ratio of grass carp in the 0.1％compound acidifier group and 0.2％compound acidifier group was significantly increased(P＜0.05).Compared with the control group,the crude fat content of grass carp muscle in each compound acidifier group increased significantly(P＜0.05),and the water content of grass carp muscle in 0.2％compound acidifier group decreased significantly(P＜0.05).Compared with the control group,the activity of lysozyme(LZM)and the content of triglyceride(TG)in serum of grass carp in the 0.2％and 0.4％compound acidulant groups were significantly increased(P＜0.05),and the content of immunoglobulin M(IgM)in serum of grass carp in each compound acidulant group was significantly increased(P＜0.05).The serum urea nitrogen(BUN)content decreased significantly(P＜0.05),total protein(TP),glucose(GLU)content and alkaline phosphatase(AKP)activity increased significantly in the 0.2％compound acidifier group(P＜0.05).The study indicates that adding the proper amount of compound acidifier in grass carp production can improve growth performance,improve body composition,enhance immunity,and improve some serum biochemical indexes,and the suitable addition level of compound acidifier is 0.2％.关键词
