I can't say that I've ever seen cattle transported around here, so I don't know how it's done. Delaware is "chicken country", and it makes me sad to see the way these creatures are treated on the way to be slaughtered. There are hundreds of crates stacked on what I would describe as flatbeds, with as many chickens as possible crammed into each crate. I often wonder how many make it thru alive and how many are DOA???
Of course we see a lot of horse trailers too, and horses are treated very good. Most of them are race horses or work horses that are privately owned tho.

If you ever watch Jane Valez-Mitchell on HLN weeknights, you would see some horrendous videos of the treatment of animals farmed for consumption. She is very much an animal rights activist and usually has a piece at the end of her show - supporting legislation for the humane treatment, etc, of all animals everywhere.
