The Purina Animal Nutrition Center sits in the hills of Gray Summit, Missouri. And it's the very heart of everything we do. On this 1,200-acre working farm, we feed more than 3,000 animals everyday. And our animal nutrionists and veterinarians live and work with the animals just like you do. Because real life tells us more than we could ever learn in a lab. Every day, we strive to do what’s best for animals. That’s why we’ve conducted more than 20,000 research studies and evaluated tens of thousands of ingredient and nutrient combinations. We have countless industry firsts, including the formulation of feeds in pellets, blocks, liquids and gels, and hold more than 100 patents for animal feed innovations. And that commitment has helped us develop products that feed more than 100 million animals every day. Since 1894, we’ve been committed to providing you with the best animal nutrition possible. So we’ve partnered with an extensive network of independent feed dealers and farm and fleet retailers who share our values to help you choose what’s best for your animals. Purina Animal Nutrition LLC, is a subsidiary of Land O’Lakes, headquartered in Minneapolis, Minnesota.Something looks off?
