It was the same cow - I'd nearly killed her, a risk you sometimes have to take. She's looking pretty good this morning.
Surprised so many think a nose bleed can be a big deal - but I'd had to pull her out of the milking pit with a tractor and chain, the chain real tight because it could barely reach her when I'd got the tractor as close as possible. I knew she was choking when I lifted her hind legs back on to the platform, got back on the tractor and pulled her clear of the edge and that's when she went limp, and she was still completely limp and floppy when I took the chain off and let her head fall back to her shoulder and waited for signs of life.
Then she flopped her head forward, started breathing again and the blood started coming out of her nose - not huge quantities, and only from the nose not the mouth but I'd only seen that sort of thing in cows that I've found dead and I wasn't too sure yet if she was going to stay in the land of the living, but her breathing was getting stronger, the bleeding stopped and a few moments later she lurched to her feet and staggered off out, trembling and staggering like a cow with massive brain damage (like ryegrass endophyte poisoning, maybe BSE or polio though I've never seen BSE, have seen the other two).
That's when I called the vet for advice on her prognosis, and he explained that the nose bleed was due to high pressure created by the chain bursting blood vessels. I'd always thought the sort of blood you see when they die came from the lungs, and didn't know if a living cow could survive bleeding lungs, or if the oxygen deprivation (which I presume caused her staggeriness) would have caused permanent damage that could kill her.
Apparently not. But it's far from her first adventure like this - she may well be getting a one-way ticket soon.
Alisonb - this is number 81, the cow whose udder I photographed a while back for your thread. She's eleven this year, going on twelve. Any normal cow I'm sure would have rested up for half an hour, but not this one.
