Resumen
Descripción
The aim of this work was to estimate the nutritional value of 300 hybrids from Urochloa interspecific breeding program. Plant biomass was harvested and subjected to a bromatological analysis to evaluate crude protein, neutral and acid detergent fiber, and in vitro digestibility using standardized methods. A large proportion of the hybrids showed better nutritional values than the genotypes used as controls. We expect to build a selection index with nutritional quality values and other previously evaluated traits to identify the best hybrids for selection.
