Effect of feeding Chamaecrista rotundifolia seed powder on the productivity and the biochemical index of native chicken

Effect of feeding Chamaecrista rotundifolia seed powder on the cholesterol metabolism of native chicken and its mechanism were investigated in Fuzhou area.240 healthy 8 week-old chickens were randomly divided into two groups by using single factor design,each group has tree replications.The chickens in control group were given basic daily feed,the chickens in experimental group were given basic daily feed and 3 g of Chamaecrista rotundifolia seed power(120 mesh) per bird,the experiment was lasted for 30 d.The results showed that,there was no significant difference in chicken productivity between two groups(P0.05).Feeding Chamaecrista rotundifolia seed powder significant deduced TCHO,TG,LDL-C contents in the chicken serum(P0.05) and increased HDL-C content(P0.05).TCHO and TG contents in the chicken muscle of experimental chicken group were significantly lower than that of control(P0.05).The test to AST and ALT of experimental chicken showed that feeding Chamaecrista rotundifolia seed powder had no harmful effect on chicken liver.Chamaecrista rotundifolia seed powder significantly decreased the HMG-CoA reductase activity.
