Abstract
This study investigated using Hedychium gardnerianum, an invasive plant, combined with dehydrated alfalfa (Medicago sativa) with varying percentages of alfalfa: control (0% alfalfa), T1 (10%), T2 (20%), T3 (30%), and T4 (40%), to enhance nutritional parameters in silage for ruminants in the Azores. Samples were vacuum-sealed and stored for 45 days at room temperature to promote anaerobic fermentation. Chemical analysis showed that alfalfa addition increased dry matter (DM) from 12.33% to 48.04% and crude protein from 11.34% DM to 24.63% DM. Insoluble fiber levels decreased, enhancing digestibility. In vitro fermentation indicated higher gas production in 40% alfalfa silage, suggesting faster fermentation. In conclusion, incorporating dehydrated alfalfa into Hedychium gardnerianum silage particularly enhances nutritional quality and digestibility. This approach offers a practical solution for ruminant feed in the Azores, particularly during feed scarcity periods.
