ProPath? Cu 170 (copper amino acid complex) is a nutritional feed ingredient for all species (except sheep and other ovine species) that contains 17 % organic copper. It is built from a unique, patented trace mineral product that combines two specific amino acids, each bound (or complexed) to a separate copper ion, in a stable, 1:1 ratio. Flexible for use in a wide variety of diets, such as conventional or specialty (like non-GMO), ProPath Cu 170 relies on two synergistic, amino-acid absorption pathways (cationic and anionic) to elevate copper mineral nutrition in the animal. Optimizing these pathways allows copper to be more effectively absorbed and metabolically available in the animal?s organs, tissues and enzyme systems. Zinpro Performance Minerals provide the highest biological efficacy of any trace mineral products on the market. For more than 45 years, Zinpro Performance Minerals have delivered positive animal performance responses and a strong return on investment in operations around the world
