The objective of this work was to evaluate the digestibility and kinetic parameters of silages of commercial and experimental sorghum genotypes grown in a crop in amazon biome to identify materials that present the best performance. The experiment was carried out in Sinop/MT with silages from 15 genotypes to evaluate gas production and in vitro digestibility and energy estimation, including BRS 658, BRS 659, Volumax, BRS Ponta Negra, 15F30005, 15F30006, BRS 511, CMSXS 5027, 5030, 5043, 5045, BRS 716, AGRI-002E, 201934B008 and CMSXS 7501. Gas production, pH, ammonia-N, and in vitro digestibility analyses were carried out, in addition to energy estimation using equations. The silages of materials with the highest gas production and digestibility were forage because they have a greater amount of digestible carbohydrates. On the other hand, the biomass and saccharine standard biomass presented lower performance because they have a higher concentration of lignin and structural carbohydrates in their composition.
