Abstract
SPF chickens were inoculated with four commercial IBD live vaccines named A, B, C, D respectively, to assess the immune effect of different vaccines by challenged with IBDV. 10 days old SPF chickens were divided into different groups and were inoculated with A, B, C, D vaccines a feather copy each chicken, challenged with vvIBDV (GD0104) 1000 LD50 doses each chicken, the protection rate of each vaccine group that challenged at 21 days old were 100%, 85%, 100%, 100% > the protection rate of each vaccine group that challenged at 35 days old were 100%, 75%, 95%, 100%. Antibody tests showed that the level of antibody titers D>A>OB) the rate of antibody turned positive! A>D>C>B; immune stress effect.. A, D >B, C. Considering of the indicators change post-infection vaccination, A and D vaccines were better than the other two live vaccines, can provide effective protection for the SPF chickens.关键词
