Who We Are

World Wide Sires (WWS) was founded in 1971 by Bill Clark, California dairyman and breeder of Cal-Clark Board Chairman (sire of Blackstar). Mr. Clark’s passion for cows and international people grew into a global business that has become a household name for farmers around the world.

In 2001, WWS was purchased by American A.I. cooperatives, Select Sires and Accelerated Genetics. The two organizations joined forces after 16 years of working with WWS to deliver industry-leading genetics to over 80 countries worldwide. Select Sires and Accelerated Genetics became a unified cooperative, with 30,000 farmer owners, in 2017. WWS continues to serve as the international marketing arm for their superior dairy and beef genetics.

The same passion for cows and people that created WWS is what drives the business today, connecting the World Wide Sires family of distributors, sales teams and valued customers.
