Chemical-bromatological composition of silages from biomass sorghum genotypes

Abstract

The biomass sorghum [Sorghum bicolor (L.) Moench] was developed for energy production, but its agronomic characteristics make it an alternative plant for silage production. This study aimed to evaluate the chemical-bromatological composition of silages from biomass sorghum genotypes. The experimental genotypes B004, B005, B009, B010, B011, B013, B015 and B020, as well as three commercially available genotypes (BRS655, Volumax and K1009), were evaluated. The pH, dry matter, ash, organic matter, crude protein, neutral detergent fiber, acid detergent fiber, hemicellulose and lignin were analyzed. A completely randomized design, with four replications, was used, having the genotypes as treatments. Although significant differences were observed among the 11 genotypes, the chemical-bromatological composition of all them showed their potential to be used for silage production.
