Resumen

La colina es un nutriente esencial para los rumiantes, involucrada en funciones metabólicas clave. El objetivo del estudio fue evaluar el efecto de la suplementación con colina protegida de la degradación ruminal (CPDR) sobre el rendimiento productivo y el microbioma ruminal en corderos. Tres corderos machos (16 ± 0.45 kg PV) fueron distribuidos en un cuadro latino 3 × 3 con doble repetición. Cada periodo experimental duró 14 días. A los animales se les asignó una dieta basal formulada para aportar 1.15 Mcal de ENg/kg de MS y 15% de proteína cruda. Se evaluaron la ganancia diaria de peso (GDP), el consumo de materia seca (CMS), la conversión alimenticia (CA), el pH, el NH₃-N ruminal y la concentración de bacterias. La suplementación con CPDR incrementó la GDP de forma dependiente del tratamiento, y mejoró la CA sin afectar el CMS (p ≤ 0.05). No se observaron cambios significativos ni en el pH ni en las poblaciones bacterianas (p > 0.05), y ambos permanecieron dentro de los rangos fisiológicos óptimos, lo que sugiere que la CPDR favorece el desempeño productivo sin comprometer la fermentación ruminal.
