Abstract: In order to investigate the differences of coccidiosis resistance between Jinghai Yellow chicken hybrid parental BB and FF chickens,30 experimental cocks of BB and FF were randomly divided into vaccine group (n=15) and control group (n=15) at 9-day-old,and then the plasmas of each group were separated from each chicken at 8 days post vaccination,and the resistant indexes were measured using biotin double antibody enzyme-linked immunosorbent assay (ELISA),the significant differences between groups were tested.The results showed that the CAT,SOD,IL-17 levels in BB vaccine group were significantly higher than that in FF vaccine group (P <0.05);The CAT level in BB vaccine group was very significantly higher than that in control group (P <0.01);The SOD level in BB vaccine group was significantly higher than that in control group (P <0.05);The CAT and GSH-Px levels in FF vaccine group were significantly higher than that in control group (P <0.05).Comprehensive analysis results shows that immune effects of BB vaccine group was superior to that of FF vaccine group,and coccidiosis resistance of BB chickens was superior to that of FF chickens.
