Sunflower (20.0% DM and 10.0% CP) was ensiled in 16 plastic experimental silos, forming four treatments: control, Sil-All (S. faecium, P. acidilactici, L. plantarum, amylase, hemicellulase, and cellulase), Silobac (L. plantarum, S. faecium, and Lactobacillus sp.), and Pioneer 1174 (S. faecium and L. plantarum). Silos were opened 125 days after ensiling and sampled to proceed chemical analyses. Pioneer increased soluble carbohydrates, ethylic alcohol concentration, and buffering capacity. This inoculant decreased pH, ammonia, and acetic acid concentration compared to control. Pioneer also increased starch content compared to control, but Sil-All decreased. The DM, CP, ADIN, NDF, ADF, and lignin contents, In vitro digestibility of the DM, DM losses, aerobic stability, propionic, butyric and lactic acids did not suffer influence of treatments.
