Efecto de aditivos químicos en la composición del ensilado de avena ("Avena sativa" L)

The objective of the experiment was to evaluate the effect of chemical additives (urea, sodium urea-benzoate, sodium benzoate, ammonium urea sulfate) in the bromatological composition of oat silage. The silages were elaborated in the Professional Academic of Zootecnia of the National University of Huancavelica by tubes of PVC of 10cm (Width) x 40 cm (Height), with sealed caps. The experimental design was completely randomized, with 5 treatments and 5 replicates. The microsils were opened 60 days after silage. None of the additives were effective in the reduction of neutral detergent fiber (FND), acid detergent fiber (FAD), hemicelluloses and FND-hemicelluloses ratio of silages. The treatments with UR, UR + BS, UR + SA favored lower values of soluble carbohydrates, in relation to silage without additives. Oat silage without additives is a strategy that can be improved with additives satisfactorily in crude protein content alone or in association with BS.
