A Method for Improving the Nutritional Value of Animal Feed

摘要

The invention relates to the use of at least one bacterial phytase in combination with one or more protease(s) in animal feed for improving weight gain and/or Feed Conversion Ratio (FCR), wherein the phytase is administered in one or more of the following amounts (dosage ranges): 1,000 FYT/kg feed, 2,000 FYT/kg feed 3,000 FYT/kg feed and wherein the protease is administered in one of the following amounts (dosage ranges): 10,000 units/kg feed, 11,000, 12,000, 13,000, 14,000, 15,000, 16,000, 17,000, 18,000, 19,000, 20,000 units/kg feed.

1. A method for increasing weight gain and/or improving Feed Conversion Ratio of farm animals, the method comprising the step of applying to the animal a feed with an efficient amount of one or more proteolytic enzymes in combination with at least one phytase wherein:
a. the phytase is administered in such amounts that the specific activity in the final feed is between 1000 FYT/kg feed and 4000 FYT/kg feed and b. the protease is administered in a dosage of between 10,000 units/kg feed and 30,000 units/kg feed.
