Effects of yeast-enriched functionalized canola meal supplementation on apparent total tract macronutrient digestibility and fecal characteristics, fecal microbiota, and immune function of healthy adult dogs

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 beta-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.
