Abstract:

The bromatological composition of wet grain silages of five forages (corn, millet, sorghum, oats and sunflower) was evaluated. A completely randomized design with five replications was used. The materials were planted on November 1, 2007 and the material to be ensiled was collected from January 15 to March 1, 2008. The material was ensiled in laboratory silos made of PVC. The silos were opened after 100 days. The material was weighed to determine the pre-dry matter and a sample was milled Willey mill. The pH, titratable acidity, dry matter (MS) and crude protein (PB), neutral detergent fiber (FDN) and acid detergent fiber (FDA), ether extract (EE) and mineral matter contents were determined. (MM). The MS contents (P <0,05) differed in the five silages. The highest CP, FDA and EE content were found in sunflower silage (P <0.05), which presented the lowest MS content (P> 0.05). The FDN contents differed (P <0.05) between silages, being the highest found in oats, which also presented the highest DM value. There was no difference (P> 0.05) of FDN and FDA contents for corn and sorghum silage. Oat silage presented the highest values ​​of MS, FDN and MM.
