milking parlour: a building in which cows are milked, and often are also fed, washed and cleaned. There are four basic designs of parlour: the herringbone parlour, where the cow stands at an angle of 45° to the milker, is commonest for large herds; the abreast parlour, where the cows stand side by side with their backs to the milker; the tandem parlour where they stand in line with their sides to the milker; the most expensive and complex of the four systems is the rotary parlour, where the cows stand on a rotating platform with the milker in the middle. Proper management of milking parlours can ensure better milk quality and yield, contributing to farm profitability and sustainability.
