Effects of early weaning on mRNA expression of mucins (MUC), polymeric immunoglobulin receptor (PIGR), and concentration of secretory IgA (SIgA) in the ileum of squabs. D1, D4, D7, D10, and D14 means 1, 4, 7, 10, and 14 days postweaning, respectively. Values are means with their standard errors of eight squabs. * and ** mean p < 0.05 and p < 0.01, respectively, within each time points postweaning. CON, control group; EW, early weaning group.
