Brewer’s dried yeast has a high nutritional value and has long been utilized by the animal feed industry as a source of protein, B-complex vitamins, and minerals. Because yeast is rich in polyphenols, mannanoligosaccharides, and β-glucans, it may also be used as a functional ingredient, providing benefits beyond that of its nutrient content. Canola meal is a high-fiber ingredient that also has unique properties, especially when it is wetted and dried using a proprietary drying system that creates a “functionalized” canola meal. In this experiment, functionalized canola meal was enriched with different levels of brewer’s dried yeast, then fed to dogs to evaluate its effects on nutrient digestibility, stool characteristics, microbiota populations, and immunity. The results showed that the yeast-enriched functionalized canola meal had no impact on nutrient digestibility or fecal characteristics. Additionally, no differences were observed in immune cell counts or immune cell activation after challenge. In conclusion, yeast-enriched functionalized canola meal may be supplemented in canine diets without negatively affecting stool quality, fecal metabolite concentrations, or digestibility. Further research is necessary to determine the effective dose of yeast-enriched functionalized canola meal, potential mechanisms of action, and other potential implications it has on canine health.
