This work aimed to evaluate the use of different additives in the bromatological composition of corn silage. The experimental design was completely randomized with five additives evaluated: no additive; silage added with urea (3.0%); silage added with limestone (3.0%); silage added with granulated sugar (3.0%); and silage with bacterial inoculant. After 60 days of ensiling, the chemical-bromatological composition of the produced silages was evaluated. Lime-added silage had higher dry matter contents (not differing from silage with no additive), mineral matter, and lignin. Silage with urea had higher values of crude protein (19.55%) and lower levels of total carbohydrates (74.29%) and non-fiber carbohydrates (27.13%). Silage with no additive had lower levels of ADF (38.99%) and NDF (19.79%) and a higher content of total digestible nutrients (73.98%). Using additives in corn silage promotes higher concentrations of acid or neutral detergent fiber, cellulose, and hemicellulose and lower TDN levels in its bromatological composition. The addition of urea provides an increase in protein levels, while limestone increases mineral material levels.
