Abstract: (201 Views) |
| This study aimed to assess and compare the impact of adding raw potato waste (RPW) and molasses, with and without bacterial inoculations, on the composition, fermentation quality, and in vitro gas production in corn silage. The experiments were conducted on 8 treatments: corn silage without additives (CS), CS with molasses at 4% (CSMol), CS with RPW at 8% (CSPot8), and CS with RPW at 10% (CSPot10). The remaining four treatments were similar to the above treatments, but with bacterial inoculants added (CSb, CSMolb, CSPot8b and CSPot10b). The greatest dry matter, crude protein, and ash as well as the lowest neutral detergent fiber, were observed in the CSMolb. CSPot10 and CSPot8 did not show any significant difference in terms of water-soluble carbohydrates. No significant differences in pH were found among the groups treated with bacterial inoculants and CSMol.The highest concentrations of lactic and propionic acids, as well as the lowest concentrations of butyric acid and Ammonia-N, were all observed in the CSMolb group.Additionally, the lowest acetic acid concentration was detected in CSPot8. Regarding gas production at 24h (GP24), the groups that received molasses or RPW (with/without bacterial inoculants) had similar values of GP24, with the only significant difference found in CS and CSb treatments. Overall, CSMolb demonstrated superior performance compared to the other experimental treatments. Additionally, CSPot8b and CSPot10b treatments exhibited favorable fermentation parameters. These findings suggest that RPW can be effectively incorporated as a component of corn silage. |
