ProPath? 4 (metal amino acid complex) is a nutritional feed ingredient for all species (except sheep and other ovine species). It contains a combination of organic zinc, manganese, copper and cobalt. It is built from a unique, patented trace mineral product that combines two specific amino acids, each bound (or complexed) to a separate metal 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 4 relies on two synergistic, amino-acid absorption pathways (cationic and anionic) to elevate trace mineral nutrition in the animal. Optimizing these pathways allows zinc, manganese, copper and cobalt 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
