Fig. 3From: Changes of the glutathione redox system during the weaning transition in piglets, in relation to small intestinal morphology and barrier functionProtein expression of (a) proliferating cell nuclear antigen (PCNA) and (b) caspase-3 in the duodenal and distal jejunal mucosa of piglets either weaned at 3 weeks of age (3w), 4 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). y,z Means without a common superscript differ for the effect of days post-weaning (DPW: P ≤ 0.05)Back to article page
