Publisher's Summary:
In a pasture outside Edmonton, Canada, you'll find a few dozen cows doing what cows do: mostly eating. The average animal spends eight-plus hours a day filling its belly, or as is the case with cows, bellies. Cows are born with the ability to digest almost any plant they can chew, thanks to a multi-chambered stomach and a helpful army of gut microbes that break down food that most mammals cannot.
The system is an evolutionary bonanza for cattle, but it's not so easy on the environment - which is why the animals at the Lacombe Research Centre are no ordinary grazers. Through a transponder clipped to the ear of each cow, scientists record when a cow sticks her head into a bin of tasty feed pellets. As she eats, a solar-powered fume hood above captures her exhalations. Laser beams surround the pasture, reading gases in the atmosphere.
