Eight geriatric Beagles (11.5\u00a0\u00b1\u00a00.38\u00a0years old) were fed each diet for 61\u00a0days in a crossover design. Food intake, nutrient digestibility, fermentation products, faecal <jats:styled-content style=\"fixed-case\">pH<\/jats:styled-content>, and faecal IgA were examined via variance analysis.
