What is a Protease? Proteases (or peptidases) are enzymes secreted by animals for a number of physiological processes, among which is the Dr. Rolando A. Valientes digestion of feed protein.

Any increased needs for protein (amino acids) for more rapid growth due to improved genetics has been traditionally met by adding more protein (or synthetic amino acids) into the feed.
