If you’ve seen pictures of cows with holes in them floating around the Internet recently and you’re wondering what is going on, you’re not the only one.
Researchers have recently opened large 8-inch holes in 14 cows on a farm in Switzerland and animal lovers and animal rights activists alike are not very happy about it, despite the fact that farmers are assuring the world that the cows feel no pain whatsoever during the bizarre procedure.
The holes are cannula openings, which allow researchers to see right into a cow’s digestive tract to monitor and observe how they process food.
The research even has a name and it is called fistulization, or, cannulation.
Fistulization is the process used to surgically create a fistula. A fistula is “an abnormal passage that leads from an abscess or hollow organ or part to the body surface or from one hollow organ or part to another and that may be surgically created to permit passage of fluids or secretions.”
What does that mean, exactly? Basically, it means that a hole, or opening, is created in a cow’s side which allows researchers to have direct access to a cow’s stomach.
This allows researchers to monitor and observe a cow’s stomach and digestive system.
The cows used in these procedures are also called cannulated cows, which refers to cows that have cannulas surgically fitted into them.
