In order to avoid negative changes in the teat ends of a cow, in particular to avoid hyperkeratoses, the invention proposes a method for operating a milking system in which at least one of the parameters from total pressure per cycle, minimum total pressure per cycle or the ratio of total suction to total pressure is determined for at least one animal of a herd during at least one part of a milking process, and is compared with at least one reference value.
