The Iowa Certificate feeder pig program is a cooperative venture established in 1978 by the Iowa Veterinary Medical Association and the Iowa Pork Producers Association. The purposes are to 1) establish a set of health guidelines for feeder pigs; 2) identify feeder pig producers meeting or exceeding the guidelines; 3) encourage increased veterinary participation in the development and maintenance of herd health programs; and 4) supply feeder pig finishers with healthy quality pigs and information about he herd of origin, vaccination history, and products used prior to sale.
