Abstract

A growing study was conducted to evaluate the impact of alternative corn residue harvesting methods and inclusion of Rumensin® on performance and methane to carbon dioxide ratio (CH₄:CO₂) of steers. Use of the alternative harvesting method resulted in greater ADG and improved F:G ratio than traditionally harvested cornstalks. Rumensin increased ADG and improved DMI; however, it did not have an impacton F:G ratio. Altering the composition of baled corn residue did affect CH₄:CO₂, while inclusion of Rumensin, whether included in the diet on a constant or rotational basis, had no impact.
