The study focuses on the production and quality of forage silages from drought-tolerant crops, with emphasis on sorghum (cv. Tarzan). The aim was to evaluate fermentation characteristics and silage quality using a biological additive (soluble Lactobacillus paracasei DSM 16245, Lactococcus lactis NCIMB 30160, Pediococcus acidilactici DSM 16243, concentration 1.25 × 10¹¹, carrier lactose) applied at 1 mL/kg and a chemical additive (composed of propionic acid, formic acid, and glycerol) applied at 8 mL/kg in comparison with a control. The results showed that the highest dry matter losses occurred in the chemically treated silage (1.19%), while the control and biological variants had lower losses (0.64–0.74%). The biological additive enhanced lactic acid production, resulting in a lower pH and improved fermentation. All variants showed good silage quality with low proteolysis. Sorghum silages represent a suitable alternative roughage source, particularly under drought conditions, while appropriate ensiling practices and additive selection significantly influence their quality.
