Jejunal and ileal villus morphology is not altered by early weaning. Jejunum and ileum samples were fixed in 10% neutral buffered formalin (NBF) and processed and stained with H&E. A: villus height and crypt depth were averaged across 12 intact villi per pig tissue section. B: the ratio of VH:CD was calculated. Values represent means ± SE for n = 7 or 8 pigs/weaning age group. *P < 0.05, Student’s t test. CD, crypt depth; H&E, hematoxylin-eosin; VH, villus height.
