Researchers at Penn State Dairy Teaching and Research Center are conducting studies that are showing promise for the adoption of 3-Nitrooxypropanol as a sustainable feed supplement for cattle. The trial results have found that the compound is successful in reducing methane emissions by approximately 25%.
3-Nitrooxypropanol is often referred to as 3-NOP. In the animal's system, "the compound inhibits an enzyme that is crucial to the final stage of methane synthesis in a cow's rumen." The study did not reveal any hindrance to the lactational performance of cows following the sustainable feed supplement. In fact, it pointed to "an increase in their feed efficiency per unit of milk yield."
The study conducted by Penn State "might be an early step toward it being approved for use."
