Values to reflect the ability of the rescued viruses in antibody induction in piglets. a-b The values to reflect the ability of the rescued viruses in anti-N protein antibody and NA induction in piglets, respectively. The values were calculated by accumulating the S/P ratios or NA titers of the serum samples collected from the piglets in the same group in different time points and dividing by the number of piglets in the group. An asterisk (*) indicates a significant difference of the ability in anti-N antibody or NA induction in piglets between the two different rescued viruses (*P < 0.05; **P < 0.01; ***P < 0.001)
