Heritage Swine as defined by The Livestock Conservancy.
Heritage Swine must adhere to all of the following:
1) True Genetic Breed. The breed is a true genetic breed of swine. That is, when mated together, it reproduces the breed type.
2) Endangered Breed. The breed is or has been endangered, as defined by The Livestock Conservancy, and appears on or has recovered from the Conservancy’s Conservation Priority List in the Critical, Threatened, Watch, or Recovering categories.
3) Long History in US. The breed has an established and continuous breeding population in the United States since 1925. If developed since 1925, foundation stock is no longer available. If more recently imported, the breed is globally endangered. (Please refer to The Livestock Conservancy’s criteria for the Conservation Priority List for details).
4) Purebred Status. Heritage Swine must be registered purebred animals or immediate offspring of registered purebred animals. Swine that are the result of a breed association sanctioned grade-up program must have obtained purebred status.
