A machine that tracks metabolic gases from cattle is helping scientists and cattle producers alike measure an animal’s feed efficiency and detect some illnesses before cattle show symptoms.

The system uses 18 sensors to measure methane and carbon dioxide emissions from a cow’s nose and mouth.

In addition to tracking feed efficiency, the system can alert producers when animals have select health problems, such as acidosis, before symptoms occur by showing when an animal records a sudden drop in the amount of methane emitted.
