Sensor-based and Visual Behavioral Profiling of Dry Holstein Cows Presenting Distinct Median Core Body Temperature

The primary objective of this study was to investigate behavioral differences of dry Holstein cows classified as HT or LT during the summer months using a dual approach that incorporated visual observations and accelerometer technology. The second objective was to investigate the transcriptome of WBC from a subgroup of HT and LT cows, to gain insights into the genetic and molecular mechanisms that underlie the physiological differences in temperature regulation between HT and LT cows, rendering them more susceptible or resilient to heat.
