1CC, control challenged pigs; AGP, CC + 55 mg/kg Aureomycin; P(OA+EO), CC + 2 g/kg of a selected formula of OA (fumaric, citric, malic, and sorbic acids) and EO (thymol, vanillin, and eugenol) microencapsulated in a matrix of triglycerides.
2SCC, sham-challenged control; SCC vs. CC (unpaired t test), ** P < 0.05.
a,bETEC F4 challenged groups were compared by PROC MIXED followed by the Tukey’s multiple comparison test. Values within a row with different superscripts differ at P < 0.05.
