This study has the objective of evaluating the quality of silage (Napier, 60%; sorghum, 30%; and sugar-cane, 10%) conserved in trench-silos. The silos were built with side and back walls made of bricks, with no waterproof or revetment process. The floor was in direct contact with the soil, and the forage was distributed in 25cm-layers and compressed with the use of a tire tractor. The biggest losses, caused by ascetic and butyric fermentation, harmful to the cattle, took place close to the walls, due to a lack of compactness and a direct contact between the forage and the soil. The poor roof also allowed the penetration of water and other agents responsible for the formation of butyric acid. It was concluded that the waterproof process is the main factor in the desirable fermentation and conservation of the silage.
