Figure 4

Effect of delay in feed access for the first 48 h post-hatch on ileal level of mRNA for gut barrier–related genes: (A) mucin 2 (MUC2), (B) Immunoglobulin A (IgA), (C) polymeric immunoglobulin receptor (pIgR), and (D) fatty acid binding protein 2 (FABP2). Insert figure B′ represents IgA mRNA expression level from −48 to 240 h post-hatch. The expression level of e19 (−48 h) birds was set to 100% and the other values are presented as % of the −48 h data. Each value represents mean ± SE of 6 birds. Different letters (large characters for fed [FD] group and small characters for not fed [NFD] group) denote statistically significant (P < 0.05) differences between means within treatment. Stars denote statistically significant (P < 0.05) differences between treatment groups for each time point.
