Silage additives were evaluated using 600 Austrian grass silage samples from the LK Silage Project 2024. Homofermentative Lactic Acid Bacteria (LAB) improved fermentation by increasing lactic acid and reducing butyric acid and dry matter losses, while heterofermentative LAB increased acetic acid and aerobic stability. Economic evaluation showed that homofermentative LAB significantly reduced nutrient losses, highlighting the practical value of LAB additives in grass silage production.

Keywords: silage quality, fermentation losses, butyric acid, aerobic stability
