Forty young Nellore bulls were used to determine the effects of different sources forage in concentrate-rich diets containing crude glycerine on feed intake, performance, and enteric methane emissions. Ten animals (397 ± 34 kg 20 2 months age) slaughtered estimate initial carcass weights, remaining 30 (417 24.7) randomly assigned three treatments with 10 replicates. The consisted [NDF from (fNDF) was fixed 15% dry matter]; corn silage, sugarcane, sugarcane bagasse; rich concentrates 10% matter glycerine. There no differences intake matter, organic protein, neutral detergent fibre, gross energy, or metabolisable energy. No type observed performance These results suggest that alternatives silage have high fibre content, such as bagasse, do not significantly affect emissions bulls.
