Proteomic identification of potential biomarkers for heat tolerance in Caracu beef cattle using high and low thermotolerant groups. [PDF]
BMC GenomicsHeat stress has deleterious effects on physiological and performance traits in livestock. Within this context, using tropically adapted cattle breeds in pure herds or terminal crossbreeding schemes to explore heterosis is attractive for increasing animal production in warmer climate regions.

Livestock Science, 2019 Abstract High temperatures cause elevation of both blood cortisol concentrations and rectal temperature, which induce the action of heat shock proteins (HSPs) to regulate cell viability against heat stress. The aim of this study was to verify the effects of high temperatures on physiological parameters and to evaluate the level of relative expression
