Dairy Farmers of America, the nation’s largest dairy cooperative, reported more than $1 billion dollars in lost sales last year during their annual meeting. The co-ops says losses were incurred as a result of lower milk prices. The co-op reported 2018’s net income was $108.5 million with total net sales of $13.6 billion, down more than a $1 billion from the year before. DFA marketed 64.5 million pounds of milk during 2018, about 30 per cent of total U.S. production.
