O’Quinn et al. (2001) reported increased IgA titers in sow’s milk, and Davis et al. (2004b) reported an alteration in the leukocyte populations in piglets fed BioMos.
Swanson et al. (2002) showed greater concentration of IgA in the ileal digesta of dogs receiving MOS and fructoligosaccharides in the diet, but not MOS alone.
Other studies with rats (Kudoh et al., 1999) have shown an increase in fecal IgA concentrations in rats supplemented with MOS.
