This study investigates how adding 3-nitrooxypropanol (3-NOP) to cattle diet affects methane (CH4) emissions, animal performance, rumen microbiome, and metabolomic profile. We tested two doses of 3-NOP (65 and 85 mg/kg of dry matter) in Nellore cattle fed a high-concentrate diet and found lower CH4 emissions without compromising the animals’ health or performance. In fact, 3-NOP increased dry matter intake and induced alterations in the ruminal microbiome. Additionally, 3-NOP promoted changes in the metabolomic profile, suggesting shifts in fermentation dynamics and nutrient metabolism. These findings suggest that low doses of 3-NOP supplementation is a strategy to reduce greenhouse gas emissions from cattle while maintaining productivity and animal well-being.
