Effects of corn silk polysaccharide on growth performance,immune function and anti-oxidation ability of meat rabbit
The purpose of the experiment was to study the effects of corn silk polysaccharide on growth performance,serum biochemical indexes,immune function and anti-oxidation ability of meat rabbit,half male and half female,single factor design,randomly divided into 4 groups,each group set up 5 replicates,each repeat 9 meat rabbits,control group feeding basic diet,corn silk polysaccharide group 1,2 and 3 were fed with basal diet supplemented with 500 mg/kg,1000 mg/kg,2000 mg/kg corn silk polysaccharide.The results showed that the average daily gain and the ratio of feed to weight were significantly increased(P<0.05)and the ratio of feed to weight was significantly decreased(P<0.05)in the two groups,the levels of IgA,IgM and Interleukin-4 in the two groups were significantly higher than those in the control group(P<0.05),the levels of serum Glutathione peroxidase and total antioxidant capacity were significantly higher in the two groups than those in the control group(P<0.05),while the levels of MDA were significantly lower in the two groups than those in the control group(P<0.05).The results showed that corn silk polysaccharide could improve the growth performance and anti-oxidation ability of meat rabbit,increase the level of serum immunoglobulin.In this experiment,the effect of adding 1000 mg/kg corn silk polysaccharide into rabbit feed was better.
