From its inception, the primary difference between Purina Mills and its competitors was an insistence on quality. In 1916, Purina Mills was the first in the feed business to establish an analytical laboratory to test the final product before it went out to customers. As the largest feed manufacturer in the United States, Purina Mills was able to insist on top quality ingredients from sellers and to this day maintains a list of “approved suppliers” so that it doesn’t waste time with those who might sell lower quality materials. Purina Mills has also spearheaded the industry’s most innovative system for testing ingredients and monitoring nutritional consistency.

The Purina Mills of today offers hundreds of products for horses, cattle, goats, swine, poultry, rabbits, game animals, exotics and many more. In fact, if it walks, crawls, swims or flies then there is a good chance Purina Mills has a product designed to meet the animal’s nutritional needs.Sold through an extensive network of independent dealers and farm and fleet retailers, there is a great chance that you are never far from a Purina Feed dealer. In 2001, Purina Mills was purchased by Land O’Lakes, Inc. out of Minneapolis, Minnesota. However, Purina Mills marketing and research are still headquartered in Gray Summit, overlooking the rolling hills of the 1,188-acre LongView Animal Nutrition Center.
