In this heat-stress assessment we conducted in commercial drylot farms in California, we found that during the afternoon dairies could use a lot of potable water (we estimated over 150,000 L per 1,000 cows during the afternoon) and that (individual) respiration rates could range from 25 to 150 breaths/min.
These results prompted me to pursue other scientific questions I addressed during my PhD:
1. How can we identify dairy cattle experiencing high heat load?
2. How can we optimize cooling strategies for lactating cows?
