Abstract
This work evaluated the effect of different wheat sowing densities (300, 350, 400 and 450 plants/m²) on the chemical composition of silage. The experiment was carried out at IFMG – Campus Bambuí, using the Brilhante cultivar. The silages were analyzed for dry matter (DM), crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), ether extract (EE), starch, total digestible nutrients (NDT) and ammonia nitrogen (N-NH₃). The results indicated that only the N-NH₃ content showed a significant difference between treatments (p < 0.05), being lower at densities of 400 and 450 plants/m², which reflects a more efficient fermentation. The other variables were not affected by the tested densities, indicating stability in the nutritional composition of the silage. It is concluded that densities between 400 and 450 plants/m² are most recommended, as they favor better fermentation quality without compromising nutritional value.
