Effects Of Allium Mongolicum Regel Extract On Antioxidation Function Activity And Serum Biochemical Parameters In Broilers

In this experiment, 330 broiler chicks (1 day–old) were selected randomly divided into 11 groups with 3 replicates, each replicate has 10 chickens. The control group were fed a basal diet, the experimental groups AWEⅠgroup, AWEⅡgroup and AWEⅢgroup were supplemented with respectically 100,300,500mg/kg Allium Mongolicum Regel water soluble extracts (AWE) of basal diet, AFEⅠgroup ,AFEⅡgroup and AFEⅢgroup were supplemented with respectically 100,150,200mg/kg Allium mongolicum Regel fat soluble extracts (AFE) of basal diet; Mixed groupⅠ, Mixed groupⅡand Mixed groupⅢwere supplemented with respectically 100mg/kg AWE+100mg/kg AFE, 300mg/kg AWE+150mg/kg AFE and 500mg/kg AWE+200mg/kg AFE of basal diet, Allium Mongolicum Regel group were supplemented with Allium Mongolicum Regel 50g/kg of basal diet. The effects of Allium Mongolicum Regel Extracst on the productive performance, nutrient digestibility, immune function, serum biochemical parameters, antioxidation function activity, small intestine mucous membrance and the microflora in caecum contents in broilers were studied. The results were as follows:The Allium Mongolicum Regel Extracts has no significantly effect on the productive performance of broilers(P>0.05), but can increase the average daily gains and feeds intake, decrease the feed conversion rate and nutrient digestibility was not significantly affected(P>0.05).The Allium Mongolicum Regel Extracst have no significantly effect on Thymus index and Bursa index in broilers (P>0.05). 500mg/kg AWE can significantly increase the spleen index of broilers (P<0.05). The Allium Mongolicum Regel Extracst have no significantly effect on the Newcastle antibody titer, phagocytosis rate of macrophages and serum Lysozyme contents. 200mg/kg AFE can significantly increase the serum ALB, but no significant influence on TP, GLB and BUN of serum in broilers. In addition, the Allium Mongolicum Regel Extracts have no significant influence on the GLU, TG and T-CHO of serum in broilers.The Allium Mongolicum Regel Extracts influenced on the serum T-AOC significantly, (P<0.05). 500mg/kg AWE +200mg/kg AFE has significantly increase the 28 days old broilers serum SOD. AWE 500mg/kg has significantly increase the GSH-PX and CAT of serum, but no significant influence on liver antioxidation function activity. AWE 500mg/kg+AFE 200mg/kg supplementation together improve the villus growth 响of jejunum in 42 days old broilers(P<0.05), increase the V/C rate of small intestine of 28 days old broilers and the V/C rate of the jejunum and the duodenum of 42 days old broilers(P<0.05),had no significant influence on the V/C rate of the ileum of 42 days old broilers(P>0.05).Except the AFEⅠgroup and the Allium Mongolicum Regel group, other experimental groups significantly decrease the E.coli of caecum contents and increase the lactobacillus of caecum contents(P<0.05),has no significant effects on the bifidobacterium of caecum contents(P>0.05).AWE 500mg/kg+AFE 200mg/kg supplementation together has positive effects on the caecum microbial community structure.
