In 1927, The Manitoba Co-operative Dairies merged with the Manitoba Poultry Marketing Association to form the Manitoba Dairy & Poultry Co-operative Ltd. Manco continued to acquire Manitoba creameries throughout the 1920s and 1930s and by 1940 had became one of Manitoba's largest producers of dairy products and distributors of poultry and eggs. In the 1950s, the Co-operative expanded their operations to include several cheese plants. By 1976, Manco's sales were almost $28,000,000 with net earnings of over $6,000,000. In 1982, the Co-op's name was changed back to Manitoba Co-operative Dairies and changed again in 1986 to Co-operative Dairies Ltd. In 1996, Manco became a subsidiary of Dairyworld Foods (Dairyland).
