Cornell launches advanced effort to study methane emissions from cows

Cornell University revealed new specialized chambers on Monday designed to measure methane and other gases emitted by cows, marking a significant advancement in agricultural sustainability research. These climate-controlled animal respiration stalls, unique in the U.S., aim to enhance farm productivity and environmental health globally.

The stalls, set up as large barn units with integrated climate control, ensure the wellbeing of the animals while allowing precise monitoring of methane emissions.


The system not only tracks methane but also measures oxygen consumption and emissions of CO2 and hydrogen in real time. This data is crucial for assessing the efficiency of various diets and feed additives, thereby optimizing meat and milk production, improving animal health, and reducing greenhouse gases and nutrient waste.

Cornell’s nutritional modeling software, CNCPS, which is used to formulate diets for the majority of North America’s lactating cows, will also benefit from the enhanced data provided by these chambers.
