Effect of urea and molasses supplementation on in vitro digestibility, feed quality of mixed forage silages

This study aims to investigate using different ratios of urea-molasses in silage food vitro fermentation, feed value and quality production feed. After being withered a little, the fodder plant was fragmented into 2–3 cm long pieces. 0, 2 4% molasses 0.5 1% urea were added. The treatment groups UM1 (control), UM2, UM3, UM4, UM5, UM6, UM7, UM8 UM9 supplemented with 1, 1.5, 1.5% 2, 4, respectively, total 54 samples, 9 × 6 parallel, prepared, vacuumed ready-made bags, stored at 25 ± 2 °C for 60 days. silages opened, pH, nutrient contents, Fleig scores (FS), digestibility parameters, energy determined, then data subjected analysis variance. effects additives added the mixed forage on all parameters found be significant (P < 0.05, P < 0.01). crude protein (CP) increased its application by UM7. Cell wall component (insoluble fibre acid detergent (ADF) neutral insoluble NDF) reduced UM9. All these applications FS. addition in gas production, while decreased production. True organic matter molasses. As result, it concluded that would appropriate increasing quality, UM3 improving true (TOMD).
