Project description:
Results from a swine demonstration project at Kirkwood Community College will help the swine industry determine the effects of using dietary phytase to reduce phosphorus. Phytase is an enzyme that breaks down a component (phytate) in grains and oil seeds, resulting in more dietary phosphorus being available to the pig. ISU Extension swine field specialist Larry McMullen coordinates the project in cooperation with Arlin Karsten, DVM, and Steve Juhl from Kirkwood.
