Abstract excerpt
Expected changes in climate warrant research on selection for a phenotypically stable cattle population that can perform consistently across diverse environmental conditions. In this study, we utilize a heteroscedastic random regression model to 1) characterize the additive genetic and other phenotypic components of dry matter intake (DMI) and respiration rate (RR) concerning the temperature humidity index (THI),...
