Our History to Today
Eighty Years in Animal Health
Back in 1943, C.W. Bloomhall started Diamond V with a dream — in his words, “to help animals do better.” He discovered that providing a feed additive created through a natural fermentation process for livestock supports healthier animals, more production, and increased immunity.
Today, that discovery remains the foundation of Diamond V’s success. Diamond V has been in the animal health business for 80 years, continuing to grow our research and improve our science and technology as we go.
