PROOF is recognition for farmers that produce free range, pastured eggs, pork, chicken, beef and lamb from animals that have been raised on pasture in open fields. The focus of PROOF is the on farm management of livestock in a farming system that provides unrestricted daytime access to actively managed, pastured range areas in an environment that encourages purposeful use of those areas. The program is your farmer's promise that the core values they operate to are transparent and easy to understand. This is their voluntary commitment to you.
