Loading plot, describing the relationship between milking-time test variables and teat characteristics, derived from principal component analysis. From this loading plot, we distinguished 4 clusters of variables: cluster 1, consisting of MPCVAC and MPCOM; cluster 2, consisting of Length, Apex, and Base; cluster 3, including AVGFLOW and PEAKFLOW; cluster 4, consisting of MTVAC and COMPRBack to article page
