Resumo

Antecedentes: O cortisol nos equinos considera-se um hormônio indicador da adaptação a fatores de estresse fisiológico, patológico e ambiental. Recentemente, tem incrementado o interesse por seu valor prognóstico em doenças críticas e como indicador de acondicionamento e rendimento atlético. Objetivo: Determinar a concentração do cortisol sérico (SC) matinal no cavalo crioulo colombiano (CCC). Métodos: Soro sanguíneo foi coletado de 62 CCC, de ambos sexos, idade média de 8,8 anos (± 5,3), clinicamente sadios, divididos em grupos segundo idade, sexo e tipo de atividade física. Resultados: A média geral da SC determinada pela ELISA tipo sanduiche foi 13,3 ± 7,4 μg/dL. Não houve diferenças signifi cativas atribuíveis ao sexo, idade ou desempenho. Conclusão: A concentração determinada pode ser utilizada como valor de referência no CCC que desenvolvem atividades de baixa exigência física.
