SLC38A2 mRNA abundance in small intestinal distribution of the suckling piglets from day 1 to 211.

1 The small intestinal mucosa samples were obtained from suckling piglets at days 1, 7, 14 and 21 of age. The expression of β-Actin was selected as an internal control in each real-time quantitative PCR. Data are expressed as the relative values to those of duodenum mucosa of 1 day old piglets. Values are mean ± SEM, n = 8. Values with different letters within the same row (A-B) or column (a-b) are different (P SLC38A2 mRNA abundance in small intestinal distribution of the suckling piglets from day 1 to 211.
