The American Livestock Breeds Conservancy (ALBC) is a nonprofit organization focused on preserving and promoting genetic diversity among rare breeds of livestock. Founded in 1977, the ALBC was the pioneer livestock preservation organization in the United States. It has since initiated programs that have saved multiple breeds from extinction and works closely with similar organizations in other countries, including the British Rare Breeds Survival Trust. The ALBC has published several books on rare breed livestock and maintains a classified advertisement system for rare breed enthusiasts.
