70 pigiets which were in the same age were randomly allotted into 7 groups. Pigs in group Ⅰ, Ⅱ, Ⅲ, Ⅳ, Ⅴ, Ⅵ were fed a basal diet supplemented with 1% Chinese herb complex respectively; while animals in group Ⅶ were fed the basal diet only as a control in the foot and mouth disease immune process. Pigs in group Ⅰ, Ⅱ, Ⅲ were immune before 5 days, 3 days, the same day continuous feeding 3 days; group Ⅳ, Ⅴ, Ⅵ were immune before 5 days, 3 days, the same day of feeding one day. These pigs Were collected Blood samples and detected NK cells on the day before immunization, 14d, 21d, 28d after immunization and the 28d after second immunization. The results showed that NK cells in dosage group were higher than control group. NK cells of group Ⅰ, Ⅱ, Ⅲ were higher than groups Ⅳ, Ⅴ, Ⅵ. NK cells in group Ⅱwere the highest. There was a statistical difference of pig’s NK cells in group Ⅰ, Ⅱ, Ⅲ and control group (P <0.05).
