The cows calving in early summer need to be in proper body condition, in addition to be intensively cooled
Jean Vincent Bioret We cooled the cows by sessions of short wetting combined with continued forced ventilation, to maintain cows at normal body temperature (< 39.0 C).
Greetings Doctor
It is clear in your article that cows that get cool have a better response in milk production and gestation, heat stress damages their physiology too much. Here it is difficult to understand this problem even and we continue with the anachronistic ideas that lower milk is due to lack of food only, when there are many factors that influence it, such as the temperatures that exist and that will increase. In a study carried out in two dairy units, it was possible to obtain values of up to 83.0 of ITH in summer, which caused a loss of production of less than 15%.
We hope to obtain new results to further demonstrate this problem and let it be understood by the staff in charge.
