I have a 5 week old bottle-fed heifer calf purchased from the local market that began showing signs of pink eye a week ago. At the first signs of clouding, I flushed her eye with salt water and her eye cleared up for about 3 days. But the infection keeps coming back. I have heard and read of several remedies,i.e. portwine, to salt, to penicillian eye flushes; even eyeball injections. What is the BEST treatment for pink eye? Also, this calf is in the pasture with goats and I have no way to separate them right now. Is there anyway to protect the goats from this pink eye?
