Onset of heat stress and effect of warm temperature on daily milk yield in Swedish dairy cattle -- Supplemental files
Description
These are the supplemental files for the article published in the Journal of Dairy Science, identified by the DOI: 10.3168/jds.2025-28225 Table S1. Correlation between multiple-day average of maximum temperature (T1d, T2d, T3d, T4d, and T5d) and multiple-day of THI (THI1d, THI2d, THI3d THI4d and THI5d) for 10 herds in Sweden. Table S2. Anova of the generalized additive model for deviations from the expected target curve of all breeds using heat load (HL) and peak yield as a linear covariable effects. Figure S1. Distribution of deviations from the expected target curve (residuals) from the fourth-order polynomial quantile regression model of lactation curves of Holstein (A), Swedish Red (B), and Jersey (C) cows. Figure S2. Smooth effect per each 5-d average of maximum temperature on daily milk yield in Holstein (A), Swedish Red (B), and Jersey (C) breed estimated via generalized additive model. The blue line indicates the estimated partial effect of temperature on milk yield per cow, the shaded region indicates standard errors, and the dashed line indicate the estimated break-point. Figure S3. Adjusted means ± SE of the deviations from the expected target curve (RES) by peak yield group for each heat load unit according to the breed, estimated using a generalized additive model. The peak yield groups were defined by splitting the cows within each breed into tertiles according to their peak milk yield.
