USE OF PROTEOLYTIC ENZYMES TO INCREASE FEED UTILIZATION IN RUMINANT DIETS

摘要

The invention provides a method of increasing fiber digestion in ruminants by providing a feed additive or feed composition comprising at least one protease. Specifically, the invention provides a method of increasing digestibility of a forage or a grain feed comprising providing at least one protease; providing a forage or a grain feed suitable for a ruminant animal; applying the protease to the forage or the grain feed; and administering the composition to the animal, whereby an increase in digestibility is effected. The invention further extends to feed additives and feed compositions comprising proteases, preparations and uses thereof.
