Fig. 3

Partial least squares (PLS) importance scores of mid-infrared (MIR) wavenumbers, body condition score (BCS), days in milk grouped by 5 days (DIM_g), milk yield (MY), days in pregnancy (DIP) for a nitrogen use efficiency (NUE), b nitrogen loss (NL) and c the 3-day moving average of dry matter intake (DMI_a), using the best prediction model for within-herd validation. The scale of important score is trait-specific, and these scores are thus only comparable within each trait. Only wavenumbers from 968.1 to 1577.5 cm⁻¹ were presented because low importance scores were observed for the other wavenumbers
