The use is provided of a non-starch polysaccharidase as a component of a dry pet food comprising 15% by weight or more of at least one cereal and less than 20% by weight of water. The effect of such a use is to decrease the viscosity of stools produced by an animal fed the food compared with an otherwise identical food lacking the non-starch polysaccharidase. The amount of non-starch polysaccharidase added to the dry pet food may be 1 x 10 -6 - 1% by weight of the dry pet food. The cereal may be any cereal ordinarily used in pet food such as wheat. The non-starch polysaccharidase may be any one or more of a xylanase, a * small Greek beta *-glucanase, a cellulase, a pectinase and a mannanase. The dry pet food may be formed by applying a solution of the non-starch polysaccharidase to extruded pellets of pet food. Alternatively, the non-starch polysaccharidase may be applied to a suitable carrier which is then mixed with other components of the food. This mixture is then extruded into pellets of dry pet food. The dry pet food increases nutrient digestibility and reduces stool volume. The food also results in higher stool dry matter, and the animal producing stools having improved consistency and appearance. |
