A third-party certification program administered by the American Grassfed Association. The program's standards require continuous access to pasture and a diet of 100 percent forage (no feedlots). Unlike the USDA's voluntary standard for grass fed claims, confinement and the use of hormones and antibiotics is prohibited. Pain relief is not required for physical alterations like docking of tails and removal of horns. No standards exist for the treatment of breeding animals, animals during transport, or animals at slaughter.
