Paul Kononoff, Professor of Animal Science, left, and graduate student Addison Carroll, hook up Lila, a 10-month-old jersey cow in the portable booth where her breath will be measured and sampled. Kononoff is measuring methane gas produced by cattle. To measure the gas, a cow is surrounded by a phone-booth like structure where the cow eats and drinks as the air is collected and sampled.
