Once again, this is a cow on the farm where I work, not one of mine. Yesterday I noticed her right front leg was considerably swollen, from top to bottom, and appeared to be painful. Today, it was still that way, and her left leg also was swollen, although not to the same degree. Both legs were trembly and she had a hard time getting up. There was no discoloration of the skin or flesh. My boss was aware of the problem yesterday, I'm not sure if she was treated with anything (if so, it was something that had no milk restriction, as she wasn't banded this morning). I'm wondering what has caused this? How can it be avoided? Is there anything I can do for the problem????? Here is everything I know about this cow (in case there is a clue in here somewhere): She's in her fourth lactation, 102K lbs lifetime. She calved on June 6, twins, had a rough time. She didn't clean for four or five days (although she was trailing most of the placenta, which I gather, is better than if it all remains inside). She received penicillin for five days after calving, I also remember giving her oxytocin to try to get her to clean, and she was treated shortly thereafter for mastitis as well. Around that time, I noticed she had some symptoms (and certainly all the risk factors!) associated with ketosis, and suggested testing her, but my boss disagreed. She has been in rough shape the entire two months -- thin, poor coat, etc. She is giving 39lbs now according to the tester's report from last Thursday, but that is down 39 lbs from the 78 lbs recorded last month. Obviously, something is going on here. She has a nasty, infected ulcer on the point of her left hip, which developed postpartum (I have a sneaking suspicion the night milker kicks the snot out of the cows to get them up, as we seem to have an inordinate number of cows who get these sores on their hips and butts. ) Since the sore is on the opposite side of the front leg giving her trouble, I tend to think it's not related. Anyway. That's all the info I have on her ... anything you guys can suggest will be, as always, much appreciated!
