Serum cortisol concentration in the Colombian Creole Horse

Background: Cortisol is indicative of adaptation to physiological factors, disease and environmental stress in equines. Cortisol recently gained attention for its prognostic value in critical disease and as an indicator of fitness and athletic performance. Objective: To determine baseline serum cortisol (SC) morning concentrations in the Colombian creole horse (CCH). Methods: Blood serum was taken from 62 CCH of both genders with and average age of 8.8 years (± 5.3), which were clinically healthy and had different performance levels. Results: The overall SC average determined by sandwich ELISA was 13.3 ± 7.4 mg/dL. No significant differences were attributed to gender, age, or performance. Conclusion: This concentration can be used as a reference value for CCH maintained in low physical activity. Keywords: adrenocorticotrophic hormone, equine, hypothalamic-pituitary-adrenal axis, stress. Resumen Antecedentes: El cortisol es un indicador de adaptacion a factores de estres fisiologico, patologico y ambiental en equinos. Recientemente, esta hormona ha ganado interes por su valor en la prognosis de enfermedades criticas y como indicador del nivel de acondicionamiento y rendimiento atletico. Objetivo: Determinar la concentracion del cortisol serico (CS) matinal para el caballo criollo colombiano (CCC). Metodos: Se tomo suero sanguineo de 62 CCC de ambos sexos, edad promedio 8,8 anos (± 5,3), clinicamente saludables, divididos en grupos segun edad, sexo y tipo de actividad fisica. Resultados: La media del CS general determinada por ELISA tipo sandwich fue 13,3 ± 7,4 μg/dL. No hubo diferencias significativas atribuibles a genero, edad o desempeno. Conclusion: Esta concentracion puede ser utilizada como valor de referencia en CCC que desarrolle n actividades de baja exigencia fisica. Palabras clave: eje hipotalamico-pituitario-adrenal , equino, estres, hormona adrenocorticotrofica. Resumo Antecedentes: O cortisol nos equinos considera-se um hormonio indicador da adaptacao a fatores de estresse fisiologico, patologico e ambiental. Recentemente, tem incrementado o interesse por seu valor prognostico em doencas criticas e como indicador de acondicionamento e rendimento atletico. Objetivo: Determinar a concentracao do cortisol serico (SC) matinal no cavalo crioulo colombiano (CCC). Metodos: Soro sanguineo foi coletado de 62 CCC, de ambos sexos, idade media de 8,8 anos (± 5,3), clinicamente sadios, divididos em grupos segundo idade, sexo e tipo de atividade fisica. Resultados: A media geral da SC determinada pela ELISA tipo sanduiche foi 13,3 ± 7,4 μg/dL. Nao houve diferencas signifi cativas atribuiveis ao sexo, idade ou desempenho. Conclusao: A concentracao determinada pode ser utilizada como valor de referencia no CCC que desenvolvem atividades de baixa exigencia fisica. Palavras chave: eixo hipotalâmico-pituitario-adrenal, equino, estresse, hormonio adrenocorticotropina.
