ABSTRACT The objective was to evaluate the effects of maturity at harvest and row spacing on fermentative profile, aerobic stability, and nutritional value of biomass sorghum (BRS 716) silage. The experiment was conducted using a split-plot completely randomized block design with three row spacings (45, 70, and 90 cm) and four maturities at harvest (70, 100, 130, and 160 days) and eight replications. Polyvinyl chloride silos of known weight measuring 50 cm length and 10 cm diameter were used for […]

The research was carried out to evaluate yield, chemical composition and losses of chopped tropical grass hays with the following forages: pearl millet (Pennisetum americanum), sudangrass (Sorghum sudanense), elephantgrass (Pennisetum purpureum) and two cultivars of forage sorghum (SF-25 and IPA-467-4-2) (Sorghum bicolor). The materials were harvested at 30% flowering, except for elephantgrass (60 days). The experiment was conducted according to a complete randomized block design, with five treatments and four replications. There were significant differences among hay productions with sorghum […]

Sorghum Agroceres 2005 (35.9% DM) was ensiled in 16 plastic experimental silos, forming four treatments: control, Sil-All (Streptococcus faecium, Pediococcus acidilactici, Lactobacillus plantarum, amylase, hemicellulase, and cellulase), Silobac (L. plantarum, S. faecium, and Lactobacillus sp), and Pioneer 1174 (S. faecium and L. plantarum). Silos were opened 120 days after ensiling and silage was sampled to proceed chemical analyses. Sil-All, Silobac and Pioneer decreased dry matter content and increased ethylic alcohol concentration and DM losses compared to control. Sil-All increased NDF […]
