Effects of microbial inoculants on chemical composition and fermentation characteristics of sorghum silage

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 content compared to control and decreased starch content compared to Silobac, but not as compared to control. Pioneer decreased aerobic stability of silage compared to control. The CP, ADIN, soluble carbohydrates, ADF, lignin, hemicellulose, and celullose contents, in vitro digestibility, buffering capacity, acetic, propionic, butyric and lactic acids, pH and ammonia concentration did not suffer influence of treatments.
