Kinetics of ADWG, SI and TI from the experimental mice. Four samples were obtained from each group at the time of necropsy. a  ADWG (g/day) = (final weight – initial weight) / days; b SI =spleen weight (g) / the weight of mice (g) × 1000. c TI =thymus weight (g) / the weight of mice (g) × 1000. Kinetics of ADWG, SI and TI demonstrated that, to some extent, GSNO improved growth performance and protected the immune organs (spleens and thymuses) of the mice during PCV2 infection. Data were presented as means ± SD. ^* P < 0.05, ^** P < 0.01 vs PV2-inoculated control; ^# P < 0.05, ^## P < 0.05 vs NC
