Abstract | Corn crop waste in the form of corn straw, cobs, and corn husks can be used as ruminant animal feed, but its utilization as animal feed is not optimal. The application of silage feed technology using local microorganism additives is expected to improve the physical quality of silage feed. This study aimed to de- termine the effect of adding local microorganisms (MOL) and fermentation time on the physical quality of corn straw silage. This study used a completely randomized design, factorial 3 × 3 with three replications. Factor I was various doses of MOL (1 %, 3 %, 5 %), and Factor II was different fermentation times (7 d, 14 d, 21 d). The variables observed included texture, color, odor, and taste. The results showed that the MOL dose and fermentation time had a very significant effect (P < 0.01) on silage’s texture, color, and odor. In addition, the MOL dose and fermentation time have a considerable impact (P < 0.05) on the silage taste. There is an interaction between MOL dose and fermentation time on silage odor. |
