Resumen

Antecedentes: El cortisol es un indicador de adaptación a factores de estrés fisiológico, patológico y ambiental en equinos. Recientemente, esta hormona ha ganado interés por su valor en la prognosis de enfermedades críticas y como indicador del nivel de acondicionamiento y rendimiento atlético. Objetivo: Determinar la concentración del cortisol sérico (CS) matinal para el caballo criollo colombiano (CCC). Métodos: Se tomó suero sanguíneo de 62 CCC de ambos sexos, edad promedio 8,8 años (± 5,3), clínicamente saludables, divididos en grupos según edad, sexo y tipo de actividad física. Resultados: La media del CS general determinada por ELISA tipo sándwich fue 13,3 ± 7,4 μg/dL. No hubo diferencias significativas atribuibles a género, edad o desempeño. Conclusión: Esta concentración puede ser utilizada como valor de referencia en CCC que desarrolle n actividades de baja exigencia física.
