In the last 40 years, Israeli researchers realized comparative studies in order to define the negative effect of heat stress in dairy cows and the effect of using cooling methods to mitigate the heat and reduce the losses in the productivity and fertility of the cows during summer.

thank you for the useful article
1- what is the effect of evaporative cooling on the floor and consequently on the udder and the feet ?
2- is there any negative effect on the cows when the relative humidity of the air is high?
3-what is the recommended airspeed over the cows ?
4- what is the recommended floor space /cow ?
