The old milk cow we were given, 15 years old, came back out from pasture completely bloated and she has just started panting excessively. She just urinated and pooped but she is standing, head dropped and breathing hard and fast. I read somewhere you have to stab them with a knife to relieve pressure? Is this true? I've called the vet but he is out on four farm calls already... Called another guy and he is busy too! What the heck do I do? I was thinking about taking her to market on Monday since I won't have any other calves for awhile but I don't know if she will make it that long.
