International Heritage Breeds Week – May 15-21, 2025

International Heritage Breeds Week is held during the third week of May each year. It aims at increasing global awareness of endangered farm animal heritage breeds. In modern animal husbandry, many of our old cattle and poultry varieties have been replaced with more “improved” types, resulting in a tremendous loss of genetic diversity. Every month, roughly one domesticated livestock breed goes extinct. The Livestock Conservancy, a conservation organization dedicated to preserving unusual breeds, hosts International Heritage Breeds Week. Just a few decades ago, nobody imagined these breeds would be on the verge of extinction. However, contemporary farming practices have resulted in a diversity reduction.

History of International Heritage Breeds Week

Ever since humans domesticated animals, we used variants of cattle and poultry for food. Naturally, generations passed down these animals. In our case, many of the adorable animals we got from previous generations will soon become extinct. International Heritage Breeds Week is a grassroots effort to ensure future generations get to see these cherished animals. Efforts have been made to protect endangered breeds like the Iron Age Pig, Shetland Duck, and Northern Dairy Shorthorn Cattle. However, even with these efforts, we are still cornered. Every year, the world loses a large number of uncommon breeds.

In May 2015, the inaugural annual Heritage Breeds Week was conducted across the U.S. to raise awareness of endangered heritage livestock and poultry breeds in the U.S. The Livestock Conservancy created a national campaign to promote the week-long event. Heritage breed farmers and enthusiasts, and the general public were invited to spread the word to their networks. The event was so successful that The Livestock Conservancy now hosts International Heritage Breeds Week every year in collaboration with a group of livestock conservation organizations all over the world. More than 15 cattle groups were involved by 2018. Together, they began providing much-needed guidance to the general public on how they could help endangered breeds.

They also started to make the case that preserving heritage breeds is more than just a hobby. It was also crucial to maintain biodiversity. Agriculture in the modern era is akin to a “race to the bottom.” The preservation of cattle diversity aids in the halting of this process. Under industrial meat production circumstances, only livestock and cattle that provide ideal yields thrive. Boutique breeds do not receive the same level of attention from the industry. As a result, it is up to individual farmers and enthusiasts to keep them going. Unfortunately, many of these individuals lack the necessary resources to do this.
