Abstract

A finishing study was conducted to evaluate the effects of dietary nitrate and sulfate on methane production in finishing cattle. Both nitrate and sulfate addition decreased DMI and ADG. In diets with no sulfate, addition of nitrate had no impact on emissions, but nitrate and sulfate in combination decreased CH4:CO2. However, neither nitrate nor sulfate had any further impact on methane production. Effect of these compounds may be diet dependent and in this study had little impact on CH4 emissions in finishing cattle.
