World Wide Sires, LTD.

About Us

World Wide Sires was founded in 1971 by Bill Clark, a California dairyman and breeder with a passion for both cows and people. Since then, we have grown into a global business that has become a household name for farmers around the world with an interest in high quality genetics and excellent service. Headquartered in Visalia, California, we are a wholly owned subsidiary of Select Sires Inc., the largest AI cooperative representing over 30,000 farmer owners across 6 continents and over 100 countries. We provide our customers with access to over 1,100 of the most diverse and sought-after sires from our three powerhouse genetic lineups; Select Sires, Accelerated Genetics, and GenerVations. Our company’s foundation was built on our commitment to our customers and our ongoing efforts to build long-standing relationships. By providing individual support and guidance to each client, we’ve consistently helped farmers meet their genetic goals year after year.
