¹Number of observations: 36 and 37 in LBW and HBW pigs, respectively; 36 and 37 in LBV and HBV pigs, respectively; 36 and 37 on the A and R regime, respectively.

²A BiW × Diet interaction was observed (P = 0.02): A regime: IGF-1 in pigs with LBW and HBW is 200 and 199 µg/L, respectively; R regime: IGF-1 in pigs with LBW and HBW is 167 and 191 µg/L, respectively.

³An EBV × Diet interaction was observed (P = 0.02): A regime: IGF-1 in pigs with LBV and HBV is 186 and 214 µg/L, respectively; R regime: IGF-1 in pigs with LBV and HBV is 178 and 180 µg/L, respectively.
