I have actually put my hands inside a cow like that, into the hole. I had gloves but I almost puked.
For all the peta-fags, these cows are used for scientific purposes. They are used to study the cows digestion and figure out what is best for cows. These cows feel no pain from it, and usually live a much longer and much better life than most cows. The cow I saw was 17 years old, which is pretty old for a cow.
