Effects of Artemisia argyi Powder on Growth Performance,Meat Quality,Lipid Metabolism and Intestinal Function of Broilers
To study the effects of Artemisia argyi powder on growth performance,meat quality,lipid metabolism,serum immu-noglobulins,antioxidant function and intestinal function of Hongyao broiler,a total of 540 30-day-age healthy male Hongyao broil-ers were randomly divided into 3 groups with 6 replicates,consisting of 30 chickens in each replicate.The control group was fed with basal diet,and the 2%and 3%Artemisia argyi powder groups were fed with 2%and 3%Artemisia argyi powder,respectively.The experiment lasted for 60 days.During the experiment,the growth performance was counted with each repetition as the unit;On the 60 th day,three chickens were selected from each replicate.The breast muscle and leg muscle were taken for meat quality detection,the serum was collected for the detection of biochemical indexes such as lipid metabolism and antioxidant capacity,and the mucosa of duodenum,jejunum and ileum were scraped to detect the content of zonula occludens-1(ZO-1),claudins(CLDN1)and occludin(Occludin).The contents of cecum were collected to analyze the diversity and relative abundance of intestinal micro-organisms.The results showed that compared with the control group,the feed weight ratio of broilers in 2%and 3%Artemisia argyi powder groups was decreased significantly(P<0.05).The muscle shearing force was significantly decreased(P<0.05),while the hydraulic capacity and the content of polyunsaturated fatty acids were significantly increased(P<0.05)in 3%Artemisia ar-gyi powder groups.The content of serum high density lipoprotein cholesterol and catalase activity were significantly increased(P<0.05),and the content of low density lipoprotein cholesterol was significantly decreased in 2%and 3%Artemisia argyi powder groups(P<0.05);The contents of serum total cholesterol and malondialdehyde were significantly decreased(P<0.05),and the con-tents of albumin,total protein and globulin were significantly increased(P<0.05)in 3%Artemisia argyi powder group.The content of CLDN1 in small intestinal mucosa and the contents of ZO-1 and Occludin in duodenum and jejunum mucosa were significantly increased in 3%Artemisia argyi powder group(P<0.05).The intestinal microflora richness index of broilers was significantly in-creased(P<0.05),the abundance of beneficial microorganisms Firmicutes was significantly increased(P<0.05),and the abundance of harmful microorganisms Proteobacteria was significantly decreased in 2%and 3%Artemisia argyi powder groups(P<0.05).In conclusion,the supplementation of Artemisia argyi powder could significantly improve the growth performance,meat quality,lipid metabolism,immunity,antioxidant capacity,the intestinal mechanical barrier function and the richness of intestinal flora.
