One hundred 17-d old weaned pigs were blocked by sex 15 and weight and randomly allotted to one of five treatment groups: negative control 16 (NC) unchallenged, corn-soy diet; positive control (PC) challenged, corn-soy diet; 17 10% DDGS diet (D) – challenged; positive control with antimicrobial regimen (PC + 18 A) – challenged; and 10% DDGS diet with antimicrobial regimen (D + A) 19 challenged. For antimicrobial-supplemented treatments, diets contained 30 g/ton 20
