Summary and Implications
Many dairy producers ( > 40+% in Iowa) are milking in stall barns or antiquated milking parlors which are achieving only 25 cows milked per person per hour. In comparison, other producers are achieving 75 cows milked per person per hour in well-designed milking parlors. This difference represents a person being three times more efficient with use of labor which translates into significant differences in farm profitability between these milking systems.
