Milking Parlor Cleaning1

D.R. Bray and J.K. Shearer 2

A survey of milking equipment in Florida revealed that many of the pulsators and vacuum controllers were not functioning properly. Research has demonstrated that major mastitis problems can occur when cows are milked with malfunctioning pulsation and vacuum controllers. The most common cause of these malfunctions, is a lack of regular maintenance. If you have not performed these maintenance chores in some time, now would be a good time to start. Routine performance and use of the schedule on the back of this sheet should be helpful. The checklist can be removed and placed in or near the milking parlor to monitor maintenance items. Here are some guidelines to follow.
