| Sumario: | The objective of this study was to measure the effects of different compaction densities on the quality of sorghum silages. A completely randomized design was adopted, with three ensiling densities: 400; 600 and 800 kg/m³ and six replicates. The silages were made from sorghum plants harvested at the pasty flour stage, crushed in a self-propelled harvester, and ensiled in experimental PVC silos. After 45 days of ensiling, the silos were opened and dry matter (DM), temperature, pH, ammoniacal nitrogen, bromatological composition, dry matter intake as a percentage of live weight (CMSPV) and total digestible nutrients (TDN) were measured. Temperature, ammoniacal nitrogen and pH were affected by the densities, however, the differences did not alter the quality ofthe silages obtained. In the bromatological composition parameters, the densities did not promote changes with statistical significance. Due to the average values of DM (316 g/kg), ammoniacal nitrogen (6.84% of total N), pH (3.76), NDF (612 g/kg), CMSPV(1.94%) and TDN (602 g/kg), the silages were considered to be of good quality for feeding ruminants. Based on the results obtained, it is possible to state that the densities studied can be recommended for storage and obtaining sorghum silages of good fermentative and nutritional quality. |
