Diarrhea in preweaned dairy calves is a significant cause of morbidity and mortality. Optimizing health in this crucial period without antibiotics is of primary interest. Celmanax™ SCP (CSCP) contains derivatives of Saccharomyces cerevisiae cell wall blended with fermentation products. Mannan oligosaccharides (MOS) are yeast cell wall components with binding sites for Gram negative bacteria that lead to pathogen removal. MOS and β-glucans may produce immunomodulatory effects . Dosing with S. cerevisiae has been shown to prevent clinical signs in calves challenged with Salmonella spp. Additionally, S. cerevisiae lowered fecal scores pre- and postweaning (Alugongo et al, 2016]. Our objective was to investigate the effect of CSCP supplementation in Holstein dairy calves, on fecal pathogen shedding, overall health and average daily gain (ADG) during the preweaning period.
