Resumen
The objective of this study was to evaluate the effect of B vitamins on in vitro digestibility of dry matter (IVDMD) and organic matter (IVOMD) of diets with different source of carbohydrates (sorghum and barley grain), with five concentrations of B vitamins (BV; 0, 2, 4, 6 and 8 g kg-1 DM). There were differences (P < 0.01) for the principal effects (source of carbohydrates x concentration of BV), also for the interaction of them in both cases (IVDMD and IVOMD). At 8 g with sorghum increases the IVDMD and IVOMD, but did not change when the source of carbohydrates was the barley. The addition of B vitamins improves the IVDMD and IVOMD, also the nature and quality of the diet effect the microbial B vitamin production.
