The stress occurs by management, transport and other stressor agents that are routine in the production of beef cattle. This stress can impact in economics of system for decreasing production and quality of final product, in addition to threaten the animal welfare. The uncomfortable situation causes physiology, morphology and behavior modifications. When the animal tries to maintain homeostasis endocrine and metabolic changes occur. Therefore, understanding the hormones involved in a stress situation (hypothalamus-pituitary-adrenal activity) and their metabolites in body fluids and excreta, can help to detect animal stress. The invasive methods, as the plasma cortisol concentration, to monitor the stress are very questioned, this hormone ap...
