La investigación se realizó en el Laboratorio de Nutrición Animal y Evaluación de Alimentos - LUNEA de la Universidad Nacional de Huancavelica, con el objetivo de determinar el valor nutritivo del ensilaje de cebada - vicia en diferentes proporciones, con urea al 1% en minisilos. Se ensiló en minisilos de PVC, durante 121 días de fermentación. El diseño experimental fue completamente al azar con arreglo factorial (2x5) con 10 tratamientos: U1P1= 100% cebada – 0% vicia, con urea al 1%; U1P2= 75% cebada – 25% vicia, con urea al 1%; U1P3= 50% cebada – 50% vicia, con urea al 1%; U1P4= 25% cebada – 75% vicia, con urea al 1%; U1P5= 0% cebada – 100% vicia, con urea al 1%; U2P1= 100% cebada – 0% vicia, sin urea; U2P2= 75% cebada – 25% vicia, sin urea; U2P3= 50% cebada – 50% vicia, sin urea; U2P4= 25% cebada – 75% vicia, sin urea y U2P5= 0% cebada – 100% vicia, sin ure...

Se determinó el valor nutritivo del ensilaje de cebada - vicia en diferentes proporciones, con urea al 1% en minisilos. Se ensiló en minisilos de PVC, durante 121 días de conservación. El diseño experimental fue completamente al azar con arreglo factorial (2x5) con 10 tratamientos: U1P1= 100% cebada – 0% vicia, con urea al 1%; U1P2= 75% cebada – 25% vicia, con urea al 1%; U1P3= 50% cebada – 50% vicia, con urea al 1%; U1P4= 25% cebada– 75% vicia, con urea al 1%; U1P5= 0% cebada – 100% vicia, con urea al 1%; U2P1= 100% cebada – 0% vicia, sin urea; U2P2= 75% cebada – 25% vicia, sin urea; U2P3= 50% cebada – 50% vicia, sin urea; U2P4= 25% cebada – 75% vicia, sin urea y U2P5= 0% cebada – 100% vicia, sin urea, se utilizó 3 repeticiones por tratamiento. Los resultados demostraron que hubo variación a mayor porcentaje de vicia con la inclusión de urea al 1% incremento ...

The present study aimed to determine the bromatological composition of the vetch silage associated with barley in five proportions and two levels of urea. A completely randomized design with three repetitions in a factorial scheme of 5 x 2 (proportions, urea) was used. The ratios of vetch and barley were: 0: 100, 25:75, 50:50, 75:25 and 100:0, respectively. Urea was added in 0 and 1% levels on a dry matter basis. Micro silos of PVC tubes 10 cm (diameter) x 60 cm (height) were used for 121 days. Samples were taken from the silos to determine dry matter (DM), crude protein (CP), neutral detergent fibre (NDF), acid detergent fibre (ADF), hemicellulose, mineral matter (MM) and pH. The vetch:barley 50:50, 75:25 and 100:0 without urea had higher DM content than the ammonified silages (p<0.05). The CP increased linearly in the silages with and without urea, especially the vetch/barley ammoni...
