Abstract
Methane emissions from ruminants are of great concern as they contribute to greenhouse gasses emitted within the atmosphere. The objective of this research was to evaluate a novel biochemical compound, 3-nitrooxypropanol, on its ability to reduce methane emissions and its impact on animal performance and rumen fermentation when fed to lactating dairy cows. In Study 1, feeding 2,500 mg/d 3-nitrooxypropanol in a 38% forage diet reduced methane emissions by 60% and increased body weight gain. In Study 2, feeding 1,250 and 2,500 mg/d 3-nitrooxypropanol in a 60% forage diet reduced methane emissions by 23 and 37%, respectively, and increased nutrient digestibility. In both studies, feed intake and animal performance were not negatively affected. These findings suggest that 3-nitrooxypropanol can reduce methane emissions from lactating dairy cows without adverse effects.
