The retrospective study was conducted on a commercial dairy farm located in Sachsen-Anhalt, Germany from May 2010 to October 2012.
The herd consisted of 1150 Holstein dairy cows with an average milk production of 10,345 kg (4.0% fat and 3.3% protein).
The barn was positioned in a NE–SW orientation with open ventilation and a mechanical fan system.
Sixty fans were installed above the stalls, and were controlled manually
by the farm manager.
All cows were housed in a free-stall facility with slattedfloors and beds equipped with rubber mats.
Group composition was dynamic with cows entering and leaving the experiment, depending on their calving dates.
Cows were fed a TMR. The rations were formulated to meet or exceed the requirements of the National Research Council[27].
