One 15 hundred 17-d old weaned pigs were blocked by sex and weight and randomly 16 allotted to one of five treatment groups: negative control (NC) unchallenged, corn17 soy diet; positive control (PC) challenged, corn-soy diet; 20% DDGS diet (D) – 18 challenged; 5% soybean hulls diet (SH) – challenged; and SH sprayed with 19
