Led by Geoffrey Dahl · Animal Sciences
What we study
The Dahl Lab studies how management practices like photoperiod and heat stress affect dairy cows' health and milk production. They use experiments to understand physiological changes during lactation and apply findings to other livestock like sheep and goats.
