Productivity and preferences by forage of dairy cows grazing an intensive silvopastoral system from high Andean area of Roncesvalles, Tolima

Abstract

P?ginas 29-35Recurso Electr?nicoSe evalu? la productividad de vacas lecheras y la preferencia de forraje en un sistema silvopastoril (SSP) de sauco (Sambucus nigra) asociado con pasto kikuyo (Pennisetum clandestinum) en una ?rea alto andina del Tolima. Se confirm? una buena interacci?n de las especies en el SSP, bajo las condiciones clim?ticas de la zona, pues mostraron caracter?sticas productivas similares a otras zonas, reportadas en art?culos cient?ficos. Las vacas prefirieron la gram?nea respecto al sauco, pero la producci?n de leche mostr? diferencias significativas entre tratamientos, revelando efectos ben?ficos del SSP sobre la producci?n de la leche.ABSTRACT. Productivity of dairy cows and preferences by forage were evaluated in a silvopastoral system (SSP) of elderberry (Sambucus nigra) with kikuyu (Pennisetum clandestinum)in a high Andean area from Tolima. Results confirm a good interaction between these species in SSP, under specific climate conditions of the area, because the SSP showed productive characteristics similar to other areas, reported in scientific papers. Cows preferred intake grasses rather than elderberry forage, but milk production was better in SSP than Control, suggesting benefic effects of SSP on milk production
