Values represent mean ± SD (range) unless otherwise indicated. Data were evaluated with ANOVA and Tukey's honest significant difference for multiple comparisons. Values in the same row with the same superscript are not significantly different. FiltMid (Miris HMA), FTMid1 (MilkoScan), FTMid2, (LactoScope), and Near (SpectraStar). FiltMid, filtered midinfrared; FTMid, Fourier-transformed full-spectra midinfrared; Near, near infrared.
