Mintrex chelated trace minerals from Novus International Inc. belong to a new feed ingredient category, according to the Association of American Feed Control Officials, which accepted the new feed ingredient definition on July 31.

The Division of Animal Feeds within the U.S. Food and Drug Administration Center for Veterinary Medicine accepted the chelated trace minerals category earlier this year and recommended that AAFCO accept this definition for inclusion in its official publication. “The formation of a new feed ingredient category for Mintrex is an extremely important step that gives us the opportunity to define a new class of trace minerals,” said Dr. Chris Knight, vice president of research and development for Novus.


In scientific terms, chelation means the trace minerals in Mintrex are bound with a ligand. This creates a stable complex in the acidic pH of the upper gastrointestinal tract; reduces break-up, or dissociation, of the mineral; helps reduce losses caused by antagonisms; and protects the mineral for efficient delivery and uptake in the small intestine.
