Holy Cow!

ah..rumen noodles are great!!

GOOD ONE i WAS THINKING THAT SAME THING MATE

Well cows are Ruminants.... But its not the "rumen fluid" they want. There are actually no secretions in the rumen. Bacteria live in there and ferment the cellulose they eat making it wet and gross like that... But since bacteria can only go through part of the digestion process (the part the cow cant) That leaves most of the energy available for the animal to digest. They want the bacteria, to give to the sick cow.

That is not the point though. More often those holes are for research purposes rather than medicinal reasons. Those holes are expensive....normal cows dont get them.

Close but no cigar. This particular cow was used in a demonstration for veterinary students. Besides that they were used for a study in how different coarseness of the feed results in the development of the ruminal papillae and thus how well the nutrients are absorbed.
Have never heard of rumen "transfer" but sounds interesting. Don't think it is done in Denmark where this video is from.

I saw something similar a couple of years ago, they do this in order to study what kind of food or grass the cow eat(when they are free) and what kind of sustitute can use.

They do that so vegetarian people can get something to eat out of a cow, the semi digested green stuff, it's rich in fiber =)

When the guy pulls that ring from the hole the cow moves and you can see it's head behind him, you can even see when the cow moves its tail
