Effects of compound Chinese herbs on growth performance,nonspecific immunity,and intestinal digestive enzyme activity of Acanthopagrus schlegelii
摘要
Abstract
This study aims to explore the effects of compound Chinese herbal medicine on the growth performance,nonspecific immunity,and intestinal digestive enzyme activity of Acanthopagrus schlegelii.Compound Chinese herbs are prepared by combining Massa Medicata Fermentata,Fructus aurantii,Codonopsis pilosula,Eucommia ulmoides,Lonicera japonica,Astragalus membranaceus,Asparagus cochinchinensis,Rheum palmatum,Agrimonia pilosa,Ophiopogon japonicus,Isatis tinctoria,and Artemisia argyi.The compound Chinese herbal medicine was added to the basal diet in gradient(0%,0.4%,0.8%,1.2%,1.6%,2.0%)and fed to A.schlegelii for 28 days.The results show that the weight gain rate(WGR)and the specific growth rate significantly increase(P<0.05),while the feed conversion ratio(FCR)significantly decreases(P<0.05).The WGR increases by 14.5%,while the FCR de-creases by 16.3%.At the 0.4%supplemental level of the compound Chinese herb,the total cholesterol(TC),triglyceride(TG),and low-density lipoprotein cholesterol(LDL-C)contents in serum significantly decrease.At the 0.4%,1.2%,and 1.6%supplemental levels(P<0.05),the TC significantly decrease,and the LDL-C contents de-crease in all the Chinese herbal medicine supplemental groups(P<0.05).The superoxide dismutase and catalase activities greatly increase in the Chinese herbal medicine supplemental groups(P<0.05).Lastly,the amylase,lipase,and trypsin activities in the addition group are significantly higher than those in the control group(P<0.05).In con-clusion,adding the compound Chinese herbal medicine at an optimal amount of 0.4%-1.2%can improve the growth performance,non-specific immunity,and intestinal digestive enzyme activity of A.schlegelii and effectively im-prove its blood lipid.关键词
