Abstract:

 To study the effects of ginseng stem and leaf polysaccharide (GSLP) on small intestinal mucous tissue development and immune cells of chicken,600 of 7 days healthy Hy-line Variety Brown chicken (52.79±4.58 g) were freely divided into 10 treatments,60 chicken per treatment (3 replications,20 chicken per replication),5 treatments were included in normal fed group and others were in immune depressed group.The additive levels of GSLP were 0,0.2,0.4,0.8 and 1.6 g•kg-1 in each group based on basal diet.After feeding stage,9 chicken of each treatment (3 per replication) were randomly selected for samples collection of jejunum and ileum.The results showed that:(1) GSLP improved villus width and surface area of jejunum (P<0.01),0.8 and 1.6 g•kg-1 GSLP decreased villus height and recess depth of ileum (P<0.01),but GSLP had no significant effects on villus to gland ratio;(2) The interactions of GSLP with immune state were observed in jejunum villus height (P<0.05) and mucous thickness (P<0.01),and ileum villus height (P<0.05);(3) 0.4,0.8 and 1.6 g•kg-1 GSLP increased the amounts of CD3+ T lymphocyte(P<0.05),and 1.6 g•kg-1 GSLP increased the amounts of mast cell (P<0.05) in jejunum,and dosage effects were existed in the influence of GSLP on immune cells.In conclusion,GSLP had somewhat improvement on small intestinal mucous tissue development,but had no significant influence on nutrients absorptive function;0.4 to 1.6 g•kg-1 GSLP increased the level of jejunum mucous immunization;and GSLP could improve the development of jejunum villus height and mucous thickness depressed by cyclophosphamide in early trial stage.
