This is one of the reasons I choose not to eat dairy from huge producers. I am not fan of PETA and the like, but there is no excuse for animals to be treated this way.

This is a 5,000 cow operation. There is simply no way to manage the health of that many animals and really know what's going on with each one.
Warning, it's disturbing.
