I have a full sized cow that is 3 years old and seems to be in some pain. She is bleeding some from her female parts and it also has a little white (possibly puss) mixed in with it. She slipped her calf last year, and has been locked up without a bull until around a month ago. Just about 3 days ago though the bulls were chasing her and a bull I didn't want breeding her jumped the fence that is a lot bigger than the bull I wanted breeding her. Since I seen the bulls chasing her she has been in pain and bleeding, what could be wrong and what should I do? I've heard sticking a bolus up in there to fix some problems would this and a dose of penicillin do the job? Is it worth a try?
