The effects of Schisandra chinensis extract on growth performance,intestinal morphology,and immune function of piglets
The aim of this experiment is to investigate the effects of Schisandra chinensis extract on the growth performance,intestinal morphology,and immune function of piglets.400 28 day old healthy and in good condition ternary hybrid pigs were randomly divided into 4 groups,with 10 replicates per treatment and 10 pigs per replicate.Add 0,200 mg/kg,400 mg/kg,and 800 mg/kg Schisandra extract to the basic diet as the experimental feed,pre feed for 3 days,and conduct a 28 day trial.The results showed that supplementing with 400 and 800 mg/kg Schisandra extract significantly increased the final body weight of piglets by 6.25%and 4.61%(P＜0.05);Significantly increased the average daily weight gain of piglets by 15.67%and 10.95%(P＞0.05);Significantly reduce the feed to weight ratio of piglets by 10.41%and 9.09%(P＜0.05);In addition,the extract of Schisandra chinensis from 0 to 800 mg/kg had no significant effect on the feed intake of piglets(P＞0.05).800 mg/kg Schisandra extract significantly increased the serum IgM content of piglets(P＜0.05);The extract of Schisandra chinensis with a concentration of 200-800 mg/kg significantly increased the serum IgG content of piglets(P＜0.05);400 mg/kg Schisandra extract significantly reduces serum IL-1 in piglets β Content(P＜0.05);In addition,Schisandra chinensis extract has effects on serum IgA and TNF in piglets-α The content had no significant effect(P＞0.05).The villus height of piglets in the 400 and 800 mg/kg Schisandra extract groups significantly increased(P＜0.05);The depth of jejunal crypt and V/C value of piglets in the 400 mg/kg Schisandra extract group were significantly increased(P＜0.05);The ileal villus length and V/C value of piglets in the 400 mg/kg Schisandra extract group were significantly increased(P＜0.05);In addition,the extract of Schisandra chinensis from 0-800 mg/kg had no significant effect on the morphology of the duodenum and the depth of the ileal crypt in piglets(P＞0.05).Under the conditions of this experiment,the optimal amount of Schisandra extract added is 400 mg/kg.
