This method is called “Fistula” and it let scientists to test the cow’s process of digestion.
A fistula is an abnormal anastomosis, that is, an abnormal connection between two hollow spaces (technically, two epithelialized surfaces), such as blood vessels, intestines, or other hollow organs. Fistulas are usually caused by injury or surgery, but they can also result from an infection or inflammation.
