Values with different superscripts within the same column differ significantly (p < 0.05).
1
TP, total protein; ALT, alanine aminotransferase; Ig, immunoglobulin.
2
NC, negative control (piglets were free of the challenge); PC, positive control (piglets were challenged with ETEC on the 11th day of the experiment); CS, PC piglets supplemented with 40 g/t colistin sulfate; and GOD, PC piglets supplemented with 200 g/t glucose oxidase. Samples were analyzed on the 21st day of the experiment.
