Immunohistochemical scores and light micrographs of DAB stained jejunal and ileal sections of calves. a Jejunal immunohistochemical scores. b Representative photomicrographs of DAB stained jejunal sections in the BTM, UWM, PWM, and AWM groups (H & E 40 × original magnification). c Ileal immunohistochemical scores. d Representative photomicrographs of DAB stained ileal sections in the BTM, UWM, PWM, and AWM groups (H & E 40 × original magnification). Intestine pictures from the calves receiving bunk tank milk, untreated waste milk, pasteurized waste milk, or acidified waste milk after feeding colostrum, respectively. Analyses of the jejunum and ileum sections from all the calves revealed that TLR-4 cells exhibited brown particles in the epithelium, which was clearly detected in the BTM group, a few detected in the UWM group, and more were observed in the PWM and AWM groups
