I would think farmers or any that take care of their animal would not intentionally put animals in danger if they can afford it.  I would think this is an economic reason behind this lack of protection.  It is interesting to think that i had come across an old book, standard of how building for animals should be build and i was amazed at the requirement they put on building to make sure animals are healthy. This all has to do with economics....are most farms these days owned by farmers or by corporation that sees only the bottom line and that those that take care of the animals have no say on their welfare.  Yea sound like something to push for.
