I have a cow that my phone in vet says it looks like cancerous eye. She is healthy as a pig and has a 4 month calf on her that’s doing good. I have giving her 2 rounds of Bio-mycin, first thought it was pink eye and treated with bio mycin. It went from bloody red look to normal fleshy look after 3-4 weeks; Ad time progressed she started to show heavy white matter in eye and draining heavily clear liquid. I gave her another round and after 2-3 weeks it looked better but 3 weeks after that the white matter came back but not as bad. My question now is, can I give another shot of bio mycin? And next question is it ok to spray some Vetricide eye spray in it. I’ll try to get new pics when I do this but with my back surgery I’ll have to depend on my helpers to catch her. I can give shot and spray eye when caught in head gate. She is raising a 3 month old calf now and other than this looks healthy and strong. Thanks for advice here.
