Estatus de selenio en equinos Criollo-Chileno a pastoreo y su respuesta a la suplementación

Abstract: RESUMENObjetivo. Dos experimentos se realizaron para determinar el estatus de selenio en equinos Criollo-Chileno a pastoreo y, evaluar la respuesta a la suplementación con Na2SeO3. Materiales y métodos. Exp.1A caballos pertenecientes a 10 criaderos del sur de Chile se les determinó la actividad sanguínea de glutatión peroxidasa (GPx, EC.1.11.1.9) (AcGPx). Los animales pertenecieron a 3 grupos, pastoreo de otoño (PO, n=40), pastoreo de otoño y suplementados con avena (PO+A, n=47), y, pastoreo de primavera (PP, … Show more
