Evaluation of practical dry dog foods suitable for all life stages.
We evaluated the nutritional adequacy of 2 dry-type commercially prepared dog diets by use of a gestation/lactation/growth protocol outlined by the Association of American Feed Control Officials. Both diets were formulated to contain minimal concentrations of nutrients, compared with canine nutrient requirements listed in the 1974 or 1985 National Research Council publications. Although there were no significant differences in the performance of dogs fed either diet, only one of the diets (diet 2) passed the complete life-stage protocol test. The nutritional profile of diet 1 was only sufficient to support a claim of complete and balanced nutrition for adult maintenance. Any commercial dry dog food meeting the nutrient levels in diet 2, and of similar nutrient bioavailability, should also pass an Association of American Feed Control Officials complete life-stage protocol test.
