Countries such as Denmark are urged to reduce feed antibiotic usage because of possible residues in meat and manure. Feed enzymes may be a profitable solution. They are natural catalysts and compliment the pigs own intestinal enzymes helping to digest raw materials in the diet. Pigs with feed enzymes in the diet have improved digestibility, need less feed intake to maintain growth and excrete less manure. Feed enzymes can contribute to reducing pollution risks by decreasing the nitrogen concentration in the manure spread on the land.
