PFI producers have been researching alternative methods of parasite management for at least five years, much of that time with the aid of a grant from the Organic Farming Research Foundation. The interest in alternative parasite management has grown along with specialty markets for organically raised meats. So far, the on-farm investigations have failed to discover a “silver bullet” treatment as effective as the synthetic wormers used in conventional livestock production. We are, at least, learning how to do this kind of research.
