Anotations

Scope note:

Relatively large structures for sheltering and milking dairy cows, typically with at least a few dozen stalls and milking equipment; for smaller structures to house only a few cows, use "cow house"; for large structures used to provide beef cattle housing, use "cattle barns"; for shelters with one or more open sides, use "cowsheds."
