Results of orthogonal projections to latent structures discriminant analysis (OPLS-DA) of milk composition and properties of samples from all months, as influenced by farming system (conventional vs. organic). A: Cross-validated score values, each dot representing one farm tank milk sample. Predictive (related to response of organic or conventional farming) scores on x-axis, orthogonal (not related to response) on y-axis. Symbols indicate class belongings. B: OPLS-DA loadings, each dot represents one milk quality variable. Predictive loadings on x-axis, orthogonal on y-axis. The black dots represent response classes, gray dots represent milk parameters.
