Why do they have viral pink eye vaccines if they don't work?!
I had all my cattle vaccinated for pink eye and one has pink eye right now. He had to get antibiotic injections to treat it. I also bought antibiotic eye spray and I use that twice a day on the affected eye. I think he's recovering fast, except for one white spot on his eye.
I think the flies are the culprit and I'm doing my best to keep them away.
