The members of Dairy Farmers of America (DFA) are partners in cream. DFA is one of the world's largest dairy cooperatives, with nearly 13,000 member/farmers in 48 states. About 1.8 million cows belonging to member/farmers produce 61 billion pounds of milk a year (roughly 30% of milk production in the US), which DFA markets. Along with fresh and shelf-stable fluid milk, the co-op produces cheese, butter, dried milk powder, and other dairy products for industrial, wholesale, and retail customers. It also offers contract manufacturing services. The co-op owns more than 30 manufacturing plants nationwide. DFA, whose profits are shared based on member contribution, is a major supplier to dairy giant Dean Foods.
