The type and intensity of massage effect on the teat during machine milking is influenced by the properties of the teat-cup liner, pulsation, and vacuum level. Only with the proper interplay of these three factors is the natural defence function of the teat supported and a physiologically optimal milk-flow rate achieved. The aim of the study was to compare a triangular teat-cup liner shaft with a round one. The studies were carried out in the form of a half-udder trial on a dairy farm with an automatic milking system. The cows' teats were inspected before, during and after the trial with respect to colour, changes on the base (ring formation) and on the tip of the teat (hyperkeratoses, indurations). In addition, individual-quarter data on milk flow and milk yield was recorded. The findings underscore initial suppositions that triangular teat-cup liner shafts may reduce the occurrence of hyperkeratoses. By contrast, the round teat-cup liners used in the trial tended to exhibit better milking characteristics in terms of milk flow and milk quantity. Because of local bruising on the teat when triangular teat-cup liners are used, the latter are currently not recommended for Simmental cattle or automatic milking systems.
