<stuff about meat eating bovines>
I have never heard about that, but pigs are the worst for that kind of thing. AFAIK there has not been a single confirmed case of the old "farmer dies of heart attack and his pigs eat him" urban legend, but it sticks around because it is so very plausible.
When I was young, my father owned a drain cleaning business, and one of his machines was a great big monster that shoved out a half-inch rotating cable with a cutter on the end. It was the biggest machine of its kind, and it came with the relatively rare power cable-feed option. after destroying several cables he finally bought a 4 inch water turbine cutter and the most powerful pressure washer he could get (together with 400 feet of hose). That sucker had big ol' blades on it and it literally
screamed when it ran. You could only run it in certain kinds of pipes lest it eat holes in the pipe wall, and starting it when it was outside of a pipe was
very ill-advised.
What defeated the cable machine and required the services of the water cutter? Pig hides. You see, if a pig dies in a pig barn and the farmer doesn't notice quickly enough, the other pigs eat it. If this happens there is a good chance the hide and bones will fall or be pushed through the floor slats and into the pit under the barn. When this pit is drained into the main containment, sometimes a hide will clog the main (6-8 inch) drain pipe. Luckily this is a fairly rare occurrence (in a large farm with several barns it only happens once a year or so), to be honest it would happen even less in a farm where the farmer is more diligent about walking through the barns...
Anyway, if it isn't moving, pigs will eat it. I still thing pork tastes good though...
