Analysis of the fermentation quality of sorghum-straw-based complete feed with various fortification materials and microorganism sources

The purpose of this study was to analyze the fermentation quality of sorghum-straw-based complete feed with various fortification materials, to analyze the fermentation quality of sorghum-based complete feed with different microorganism sources, and to analyze the interaction between fortification materials and microorganism sources on the fermentation quality of sorghum-based complete feed. This study used a completely randomized design with a 3×2 factorial pattern consisting of factor A (fortification materials: moringa leaves and indigofera leaves) and factor B (types of microorganisms: cattle rumen-content MOL, cattle fecal MOL, and MA-11), resulting in 6 treatment combinations, each replicated 3 times. The variables observed included the physical characteristics of silage, namely color, texture, aroma, and percentage of mold presence. Statistical analysis showed that fortification materials had a significant effect (P<0.05) on silage texture, while microorganism sources significantly affected (P<0.05) the silage aroma. Furthermore, there was an interaction between fortification materials and microorganism sources, which jointly influenced the texture and aroma of sorghum-based complete feed silage. Based on the results, it can be concluded that the sorghum-based complete feed silage produced using fortification materials and microorganism sources demonstrated good quality. This was indicated by favorable physical characteristics—including color, texture, and aroma—that met the criteria of high-quality silage, as well as a very low percentage of mold contamination (0.00–1.16%).
