Why these cows have holes drilled into their sides

They are called "cannulated cows": They have holes cut into their stomachs for research purposes. French nonprofit L214 Ethique et Animaux is raising awareness about this controversial technique.

    They do this in massy uni in NZ also. Saw this about 30 yrs ago. In NZ they were doing it first to help them understand how the Roman works. Some of what this sites stays is right but also medication, posionous ingesting of plants can help discover a cure, and other aliments. I don’t like this being done but in the end if it’s saves cows life in future, then so be it. I don’t like experiments on any animal, but I know by doing this it will save lives further down the track.

    I encourage everyone to go visit their local ag college and look at this. I use to think the same as many of you but after knowing the purpose it’s essential to have these types of animals. 99% will live healthier happier lives than commercial cows

    This does not hurt the animal!! It’s used to give beneficial guy bacteria to cows who are need of the specific bacteria in there rumen. No different than us giving blood to other humans

    It’s done to help prevent bloat. It doesn’t bother the cows and I think they’re much happier with this than being in pain from a common medical issue.

    Can we cannulate the French for allowing this since the 19th Century?? Have the animals given us permission and if they are not in a position to give a consent, isn't a non consent no??
