Got Milk??

      Portia, a cow at Tufts university has been living with a large hole in her stomach since 2002. Its not deadly. The hole was put there on purpose so scientists can study her digestive system. Portia is whats called a fistulated cow. A fistula, or opening, is cut into the side of a cow during the surgery.

         

        

The window is plugged with a plastic cup, which scientists take off when they need to reach into the cows stomach. The rumen where the opening is made is the largest compartment and contains all of the good bugs and bacteria needed to digest food.
