GREATNESS NEVER SETTLES.
BORN FOR GREATNESS IN 1894.
Our purpose has never changed over the years. Our love of beautiful, healthy, productive animals drives everything we do at Purina. And the proof of our success is in backyards, barns, and pastures everywhere.
IT'S NOT FEED. IT'S FOOD.
The way we see it, there’s no such thing as being too careful with animal nutrition. That’s why we test each feed product at every step.
RESEARCHERS WHO GET RESULTS.
The force behind our quest for greatness is a talented group of Ph.D. nutritionists and veterinarians. Together, they have conducted more than 24,000 research studies in fields across the country and registered over 125 patents.
