Article Snippet: How the data were acquired , For all milkings performed by an automatic milking system (AMS), an on-farm long-wave near-infrared (LW-NIR, 960–1690 nm) analyzer measured the transmittance spectra of a representative raw milk sample. These measurements were acquired using a 256-pixel cooled InGaAs diode array NIR spectrometer (1.7-256 Plane Grating Spectrometer, Carl Zeiss, Jena, Germany) with a resolution of 2.86 nm per pixel, fixing an integration time of 100 ms and averaging 100 repeated measures. For the same sample, white and dark reference spectra were also acquired, and laboratory reference values for fat, protein, lactose, urea and somatic cell count (SCC) were obtained following ISO 9622 and ISO 13366-2:2006..
