As weird as this may sound, I mean literally reach in and touch the inside of the cow!
In case you didn’t know animals can live perfectly well with a permanent hole in their stomachs. Scientists call these surgically made holes, fistulas, which are covered by a canulla, a sort of cover from the outside world. They are used to test the digestibility of various cattle food, the cows are fed and as the food passes through her stomachs, scientist can just reach in and see how it is processed. As brutal as it might look, this doesn’t hurt the animals at all, it actually prolongs their life, in case of stomach disease, they can receive helping medicine directly in there.
The one thing I don’t approve of is people sticking their hand in animals just out of curiosity, like the kid in our photo. Sure it’s not something you’d call ordinary, but turning a medical procedure into a circus isn’t very ethical.












I have been learning a lot about this lately and it’s not cruel at all. They use this for research to help cows with feeding and stomach problems and so that they can learn more about cows to make their life better. So the people who think it’s cruel and it’s hurting the cow it doesn’t and it’s just a way to make it better.

that says cool in my language!
Why in the first place they want to do this to the poor dumb cow anyways??!! we are already eating the poor things, why not just put their hands up its butt? I want to see some humans with this fistulas and cannulas permanently… we got lots of fatties out there that this could help!
mankind playing god again!! why fix a good thing when it aint broke?!
Do you eat meat? Because if you do then you should know that so many more unethical things happen to the cows that end up on your plate. At least these cows get to live comfortably on a farm with people that take care of them. The hole doesn’t harm them and it can help promote better health and awareness.
What about the cows bones do they have to cut them too, when they make the operation? Or is it just a flesh?
why cant they make one that i can carve a steak off every week
what a waste of a perfectly good cow…see now its going to be ‘studied’ instead of ending up on my plate!
Anyone who said “we eat cows” is an Idiot. cows give milk. we don’t eat cows. Cattle is raised for providing us our beef.
these are Bessies, not Bossies!
Just frickin feed them grass as intended and leave them alone. This is just nonsense! They are trying to find the cheapest way possible to feed these cows. It’s all about money. Selfish I tell you, SELFISH!
ummmmm,for those of you saying it doesn’t hurt the cow or affect it i have one question. Anyone of you or the smart scientist playing God ask the cow how they feel?? Hasn’t mankind done enough by breeding all intelligence out of not just cow’s but majority of domesticated animals? Just because something CAN be done does not mean it SHOULD be done!!! Would you willingly allow someone to cut a permanent hole into your body?!
oh my goodness! Poor cow and just think i wanted to come back reincarnated as a cow because until today before my calpoly pomona visit, I said cows just graze and eat grass in the pasture, not anymore, then again have you seen some of those dairy farms on the ramona expressway…….really sad.
Hello! thanks for the information about rumen fistulation and cannulation in cattle. Am a veterinary Surgeon at Makerere University and we have been doing these procedures for some time now on a digestability research project. the cows worked are fine but the is one in a cohort of 4 animals that has kept detoriating in body condition and we have treated for any possible diseases but no good results. could you be having an idea on this complication?
