TL;DR: The RR was altered in every seasons of the year and herds, showing a constant necessity of thermolisys and the effects of month of collection and herd were significative for all variables.

TL;DR: The models developed to predict the effective thermal conductivity of the coat must take differences into account because the thermal gradient parallel to the skin surface is not negligible for Holstein cows under the sun in a tropical environment, as well as the other traits.

TL;DR: The main variables which act in the adaptive profile and the dynamic of the thermoregulatory responses of Sindi and Girolando dairy cows in tropical conditions were determined using multivariate analyses as the auxiliary method.

TL;DR: The addition of Se in the diet reduced endogenous heat by reducing respiratory thermolysis and the superficial temperatures of the skin and epidermis, improving sensible and latent heat dissipation and keeping the rectal temperature within normal limits.

TL;DR: A preliminary AI was developed, able to measure the level of adaptability of dairy cows under tropical region, using multivariate analysis to "weigh" the influence of each variable in the animal responses.
