Abstract

Feed supply fluctuation remains a major constraint for ruminant production in tropical regions, where green forage availability decreases sharply during the dry season. Ensiling corn stover is a strategic approach to preserve feed while maintaining nutrient quality. This study aimed to analyze the physical quality, nutrient composition, and profile of lactic acid producing yeast in corn stover silage. The experiment was arranged in a Completely Randomized Design consisting of three treatments with four replications: P0 (without additive), P1 (with 5 percent molasses), and P2 (with ground corn). The evaluated parameters included pH, color, aroma, texture, dry matter, organic matter, crude protein, and yeast characteristics. The research was conducted at the Faculty of Animal Science, Universitas Brawijaya. The expected results indicate that the addition of molasses and ground corn enhances fermentation quality by lowering pH, improving nutrient stability, and supporting beneficial yeast activity that contributes to lactic acid formation. This study provides new insights into the role of lactic acid producing yeast in corn stover silage and supports sustainable feed preservation for ruminant livestock in tropical environments.
