Dr. John Patience is a Professor of Animal Science at Iowa State University. His research on mineral nutrition has included detailed investigations on the growth, metabolic and physiological implications of dietary electrolyte balance and the growth, metabolic and health implications of mineral contaminants in drinking water. Most recently, he has sought greater clarity in our understanding of the complex interaction between phosphorus, phytase and calcium.
