Which statement is true about parallel milking parlors?

• A. Cows enter in groups and leave in groups or individually.
• B. Cows stand perpendicular to milkers.
• C. In parallel parlors, milking begins as each cow enters.
• D. Milking takes about 60 minutes.

Answer: (A)

In parallel milking parlors, several cows are milked at the same time because the stalls run side by side along the milking area. Cows move through the parlor in groups, and once their milking is finished, they can exit as a group or one by one depending on how the line is run. This grouping flow is a characteristic feature that makes parallel parlors efficient for handling multiple cows at once. The other statements don’t fit as well. Cows in parallel parlors stand with their sides toward the milker, not perpendicular to it. Milking doesn’t necessarily begin as each cow enters; the milking unit is attached and started when the cow is in position. And milking a whole herd typically takes longer than an hour, so 60 minutes is not a realistic general duration.
