Growth performance between IUGR and NBW piglets. a Body weight in the IUGR and NBW piglets; BW, body weight. The data are expressed as the lsmeans ± SE, and the associated P value was presented to indicate statistical significance between the IUGR and NBW groups. b Body weight of the IUGR piglets relative to that of the NBW piglets. c The average daily gain in the IUGR and NBW piglets. ADG, average daily gain. d Average daily gain of IUGR piglets relative to that of the NBW piglets
