 These tasks were performed by a "dairymaid" ("dairywoman") or "dairyman".The word "dairy" harkens back to Middle English "dayerie", "deyerie", from "deye" (female servant or dairymaid) and further back to Old English "dæge" (kneader of bread).With industrialization and urbanization, the supply of milk became a commercial industry, with specialized breeds of cattle being developed for dairy, as distinct from beef or draught animals.
