about 10 days ago i had a cow with a really bad watery eye and the start of the white ulcer. I have been having a lot of trouble with pinkeye this year for some reason.. This particular cow was off by herself, standing in the shade.. i called the rest of the cows up and she finally decided to come.. She had her head held high and was swinging it around almost like one that has something lodged in there throat. I took her to the vet and she ruled that there was nothing stuck in her.. All her cardiovascular tests checked out good. the vet said it could be the start of rabies? She gave her some antibiotics and i took her home and put her in a lot by herself.. she seemed perfectly fine, she ate, drank and grazed on the little bit of grass there was. her eye has cleared up and looks fine, so i was beginning to think her eye was really bothering her, causing her to thrash her head? well today i noticed the her brisket, where the skin hangs down between her front legs has swollen. she also has diarrhea that has just developed in the last day or two.. Any ideas what the problem could be? She is a 850 lb black angus heifer that should be bred... thank you
