I noticed 3 weeks ago that my Herford heifer went off hay, she would eat a little grain(coffee can full) but not touch hay. She had also lost some weight. I called the vet and she said it sounds like hardware, so we put a magnet in her, 25cc of pen 2x a day for 4 days and gave her a laxitive (pink pills) and probois, I dont know if she has/had a temp. She was getting better, always eating the grain and nibbleing the hay. I went out tonight to feed them and she dident even get up for the grain, finally she got up nosed the grain poked around and laid back down again? Tomarrow Im gonna put her back on the pen and call the vet back. Anyone have any suggestions as to what might be wrong?
