The gaping hole in the side of the cow pictured above is actually a fistula, which is used by scientists to test a cow’s digestive progress.

When the cow is eating, the fistula allows scientists to literally watch how the food is digested.

The observation procedure requires scientists to reach inside the fistula and feel the consistency of the digested food.

The fistula does not hurt the cow at all, and actually benefits them in that it makes it easier to administer medicine when they are sick.
