Degradabilidad ruminal de grasas de sobrepaso

Abstract

El experimento fue conducido para determinar la degradación ruminal de grasa de bovino y de porcino tratadas con diferentes niveles (0.0, 20.0 y 40.0%) de Cloruro de Calcio, a las 12 y 24 hr de incubación. Se utilizaron tres novillos fistulados ruminalmente, alimentados con heno de avena. Tres bolsas por tratamiento y por período de incubación con 5 gr de grasa de bovino o de porcino tratadas, fueron suspendidas en el rumen. Al sacar las bolsas fueron lavadas, secadas y pesadas, para calcular por diferencia la degradabilidad ruminal. Los resultados fueron analizados con un modelo completamente al azar con igual número de repeticiones y arreglo factorial de 2x2x3.  La degradabilidad de la grasa de bovino tratada disminuyó (P<0.05) a medida que se incrementaron los niveles de Cloruro de Calcio, a las 12 hr de incubación (42.00, 23.35 y 7.54%, respectivamente) y a las 24 hr de incubación (58.43, 29.24 y 11.44%, respectivamente). Una tendencia similar fue observada para la grasa de porcino, encontrándose valores de 47.14, 32.13 y 15.80% a las 12 hr de incubación, y de 52.07, 44.46 y 18.82%, a las 24 hr de incubación, respectivamente para los tratamientos con 0.0, 20.0 y 40.0% de Cloruro de Calcio. Se encontraron diferencias (P<0.05) entre la degradabilidad de la grasa de bovino y la grasa de porcino, en los diferentes tratamientos y períodos de incubación. El tratamiento de grasas con sales de Cloruro de Calcio disminuye su degradación ruminal, por lo que es recomendable incluir este tipo de alimentos tratados en las dietas de animales con altos requerimientos de energía.
