Cows, by virtue of the plentiful and varied bacteria in…
““Cows, by virtue of the plentiful and varied bacteria in their rumen, are able to derive energy from things that would pass through a human undigested. The prune pit has a hard, nutritionally blank hull, but the embryo inside provides protein and fat. Rumen bacteria can break down the hull and free these nutrients, though it takes them a few days. DePeters showed me one of the mesh bags. “Sometimes I put a midterm exam in there,” he said. Cows can’t digest wood pulp. “I tell my students, ‘The cow didn’t digest that material any better than you did.””
About This Quote

Cows’ rumen microbes can extract nutrients from tough plant material that humans cannot, illustrating biological specialization and limits of digestion.
In simple terms: Cows can digest things humans can’t because of microbes.
