Hello @jsalvage, this very nourished your article on what is known in livestock as estres calorico, which significantly influences the productive processes of the animal by the stresses.
Generally the animals consume pastures, what idela for tropical areas with high temperature and humidity is to have trees in the paddocks so that the animal has a pleasant microclimate to carry out the rumination of the forages, In the same way in some farms they use a kind of bath with sprinklers to reduce the stress of the animal before milking.
There are many practices the producer will adopt the one he considers to be within his possibilities.
So long, have a great week.
Thank you so much for your contribution. I really appreciate
