ఆవుల పట్ల ఎలా ప్రవర్తిస్తున్నారో చూడండి ? ఇది కరెక్ట్ విషయమేనా ?

This may look like a disturbing sight, but the gaping hole in this cow's side is actually called a fistula, and is used by scientists to test a cow's digestive process.

As the cows are fed, the fistula allows for scientists to observe how the food is digested.

This observation requires scientists to physically reach into the cow and feel the consistency of the digestion.

The cows aren't bothered by the fistula procedure at all. In fact, it's actually beneficial to the cow. If a fistulated cow grows sick, he can be administered the proper medicine directly to the stomach.
