International Heritage Breeds Day is observed annually on May 16, aiming to raise awareness and promote the conservation of rare farm animals and breeds, such as the Iron Age pig and Shetland Duck. The day highlights the importance of protecting livestock species that face harsh treatment and extinction. Farmers and ranchers typically engage their communities by offering farm tours, workshops, and lectures to educate the public about these endangered breeds. The holiday emerged from the efforts of the American Minor Breeds Conservancy, which focused on preserving livestock diversity and raising awareness about the declining numbers of rare breeds. Support from various animal conservation organizations has helped transform International Heritage Breeds Day into a movement dedicated to maintaining biodiversity in agriculture.
