our cow seems to have been bashed up by another cow or horse 3 days ago. She has swellings and gashes over her body and head and her left front knee was very swollen and sore (too painful for her to bend it underneath whilst sitting, so stuck it straight out in front). Since the trauma, it appears she is totally blind, banging into anything in her way and then just standing there with her forehead leaning into it- not knowing where to go to get out of there. She won't turn her head to the left, but either has it straight ahead or turned to the right. she often slowly turns it right around to the right toward her stomach. she only walks in circles to the right. She was eating and drinking yesterday with what I put under her mouth, but is showing extremely little desire for anything at all today. we gave her a shot of long acting penicillin on Saturday morning. are there any suggestions?
