Porthole cow.

Over a billion cows are currently grazing on lands across the world, but what do we actually know about them? They're big. They moo. They give us milk. But what else? On today's show Distillations is answering some long-standing questions about cattle. First, we find out why the effects of dairy are nonexistent for some and unbearable for others. Then, producer Zoe Sullivan takes us to a research farm at the University of Wisconsin where scientists are exploring the mechanisms of cow digestion—with a little help from the clear, removable "portholes" implanted into its research cows.
