Intestinal morphology of NBW, CUG and NCUG piglets on 26 d. A Duodenal morphology, villus height, crypt depth, ratio of villus height to crypt depth. B Jejunal morphology, villus height, crypt depth, ratio of villus height to crypt depth. C Ileal morphology, villus height, crypt depth, ratio of villus height to crypt depth. Dates are presented as means ± SEM (n = 6). NBW, normal birth weight. CUG, catch-up growth, NCUG, not catch-up growth. *P < 0.05; **P < 0.01
