Yesterday after work I went to feed hay and found nurse cow down. She was fine the day before. Called the vet out and he gave her a bottle of calcium, Dextrose and penicillin. She worked up a little and then went right back down hill from there. No clue what is going on. Doc couldn’t figure out what was wrong with her. We put a heavy blanket on her as it was quite cold. Unfortunately it doesn’t seem like anything has helped. Will keep an eye on her.. Always has to be the favorite.
