During milking the teat cup liner is the interface between the teat of a dairy cow and the milking system, so it should be very well adapted to the teat. Therefore, the aim of the present study was to determine the effect of liner type on the directly measuring teat load caused by a collapsing liner with a pressure-indicating film. The Extreme Low pressure-indicating film was used to detect the effect of six different liners on teat load. For each liner, six positions in the teat cup were specified, and six repetitions were performed for each position with a new piece of film each time. Analysis of variance was performed to detect differences between the six liners, the positions within a liner, and the measuring areas. The pressure applied to the teat by a liner depends on the technical characteristics of the liner, especially the shape of the barrel, and for all tested liners, a higher teat load was found at the teat end. In conclusion, with the help of pressure-indicating film, it is possible to determine the different effects of liner type by directly measuring teat load due to liner collapse.
在挤奶过程中，乳头杯内衬是奶牛乳头与挤奶系统之间的界面，因此它应与乳头非常适配。因此，本研究的目的是使用压力指示膜来确定内衬类型对由塌陷内衬引起的直接测量乳头负荷的影响。使用极低压指示膜来检测六种不同内衬对乳头负荷的影响。对于每种内衬，在乳头杯中指定六个位置，每次对每个位置进行六次重复测量，每次使用新的一片薄膜。进行方差分析以检测六种内衬之间、内衬内的位置以及测量区域之间的差异。内衬施加在乳头上的压力取决于内衬的技术特性，特别是筒体的形状，并且对于所有测试的内衬，在乳头末端发现了更高的乳头负荷。总之，借助压力指示膜，可以通过直接测量内衬塌陷引起的乳头负荷来确定内衬类型的不同影响。
