Villus length, villus width and crypt depth (a) in the duodenum and (b) distal jejunum of piglets either weaned at three weeks of age (3w), four weeks of age (4w), or separated from the sow at 3 d of age and fed a milk replacer until weaning at 3w of age (3d3w). Values are least squares means ± SE (n = 12 as low birth weight and normal birth weight piglets were pooled together). ^a,b Per day post-weaning, means for villus length without a common superscript differ for the effect of weaning treatment (WT: P ≤ 0.05). ^s,t Per day post-weaning, means for villus width without a common superscript differ for the effect of weaning treatment (WT: P ≤ 0.05). ^y,z Per day post-weaning, means for crypt depth without a common superscript differ for the effect of weaning treatment (WT: P ≤ 0.05)
