Paul Kononoff, Professor of Animal Science, hooks up Lila, a 10-month-old jersey cow, in the portable booth, where her breath will be measured and sampled to determine the amount of methane produced by the animal. 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. December 15, 2023.
