How to say "dairy" in Japanese

• 牛乳屋ぎゅうにゅうや
  nounCovers 'dairy' as a shop or business that sells milk, and the sense 'milkman'. A less common choice: think of a milk shop or a milkman, not a farm or factory.

  Boxing Day, when presents are given to the postman, the milkman, etc., is the first week-day after Christmas.
• ミルクプラント
  nounCovers 'dairy' in the industrial sense of a milk plant, a facility where milk is processed. A less common loanword; use it for the processing facility, not a farm, shop, or milkman.
• 搾乳場さくにゅうじょう
  nounCovers 'dairy' in the farm sense — a dairy farm, or the place where cows are milked. A less common choice; it suggests an on-farm milking operation, not a shop or processing plant.

All three are less common ways to render 'dairy': use 牛乳屋 for a milk shop or milkman, 「ミルクプラント」 for a milk-processing plant, and 搾乳場 for a dairy farm or the place where cows are milked.
