BW—birth weight; WW—weaning weight; ADG—average daily gain; NC-F—not cross-fostered; C-F—cross-fostered; LBW—low birth weight; IBW—intermediate birth weight; HBW—high birth weight; N _{(NC-F, LBW)} = 20, N _{(C-F, LBW)} = 20, N _{(NC-F, IBW)} = 20, N _{(C-F, IBW)} = 20, N _{(NC-F, HBW)} = 20, N _{(C-F, HBW)} = 20, N means the number of piglets per group; SEM—standard error of mean; ^{a, b}—Values with different superscripts differ significantly (p < 0.05) among different treatments (columns).
