Technical Abstract: A galactoglucomannan oligosaccharide (GGMO) obtained from fiberboard production was evaluated as a dietary supplement for dogs. The GGMO substrate contained high concentrations of mannose, xylose, and glucose oligosaccharides. Adult dogs assigned to a 6x6 Latin square design were fed six diets, each containing a different concentration of supplemental GGMO (0, 0.5, 1, 2, 4, and 8%) that replaced dietary cellulose. Total tract dry matter (DM) and organic matter (OM) apparent digestibilities increased (P < 0.0001) linearly, while total tract crude protein (CP) apparent digestibility decreased (P < 0.0001) linearly as the dietary GGMO substrate concentration increased. Fecal concentrations of acetate, propionate, and total SCFA increased (P 0.0001) linearly whereas butyrate concentration decreased (P 0.0009) linearly with increasing dietary concentrations of GGMO. Fecal pH decreased (P 0.03) linearly as dietary GGMO substrate concentration increased whereas fecal score increased quadratically (P 0.0001). Fecal phenol (P 0.05) and indole (P 0.01) concentrations decreased linearly with GGMO supplementation. Fecal biogenic amine concentrations were not different among treatments except for phenylethylamine, which decreased (P < 0.0001) linearly as dietary GGMO substrate concentration increased. Fecal microbial concentrations of E. coli, Lactobacillus spp., and Clostridium perfringens were not different among treatments. A quadratic increase (P 0.01) was noted for Bifidobacterium spp. as dietary GGMO substrate concentration increased. Data suggest positive nutritional properties of supplemental GGMO when incorporated in a high quality dog food.
