Degradabilidad ruminal de forrajes y residuos de cosecha en bovinos Brown Swiss

Abstract

El objetivo del trabajo fue determinar la degradabilidad de asociación de forrajes y de residuos de cosecha comúnmente utilizados en la Región de Huancavelica en la alimentación de bovinos. Se evaluaron las asociaciones trébol blanco-ryegrass italiano y el trébol rojo-dactylis, y los residuos de cosecha: maíz chala, paja de avena, arveja, habas y quinua. Para la determinación de la degradabilidad de la materia seca (MS), proteína cruda (PC) y fibra detergente neutra (FDN) se utilizaron tres bovinos Brown Swiss, fistulados en el rumen. Los forrajes y los residuos de cosecha fueron colocados en sacos de nylon e incubados por 4, 8, 12, 24, 48, 72 y 96 horas. El tiempo cero (t0) fue utilizado para el cálculo de la fracción soluble. Las degradabilidades de la MS, PC y FDN fueron influenciadas por los forrajes y residuos de cosecha (p<0.05). La mayor degradabilidad potencial de la MS y PC, y degradabilidad efectiva de la MS, PC y FDN le confieren al trébol blanco-ryegrass italiano un buen potencial nutritivo para los rumiantes. La tasa constante (C) de degradación, degradabilidad potencial y degradabilidad efectiva de la PC permite considerar a los residuos de arveja, habas y quinua como recursos alimenticios de alta calidad nutricional. Por el contrario, la degradabilidad efectiva de la PC a la tasa de pasaje de 5%/h indica que el maíz chala y la paja de avena son alimentos de mediana calidad.
