Summary

A series of short duration experiments show that the way in which the milking machine cluster is removed from the udder influences the rate at which new udder infections occur when bacterial exposure is high at the end of milking. Shields fitted in the base of the liners controlled most of the infections caused by abrupt removal of the cluster.
