Lower concentrations of coliform bacteria in maternal colostrum (MC) have been associated with enhanced IgG absorption in calves. Mannan-oligosaccharide, a gut active carbohydrate (GAC) derived from yeast cell walls, can adsorb pathogens expressing type-1-fimbriae, which reduces their ability to colonize the gastrointestinal tract. Results of preliminary research suggest that feeding GAC in colostrum enhanced serum IgG concentration in calves. The purpose of this study was to investigate whether addition of a GAC (Bio-MOSĀ®. Alltech, Inc.) to colostrum would increase IgG absorption in newborn calves.
