Currently I have 2 options for treatment, not counting preventative vaccines. They are LA200 and an eye patch. There used to be a treatment called I-Ball years ago that was very effective, but is no longer available for whateaver reason. Also, there was some spray for the eye that was either red or blue that I can't seem to find but it's effectivness was limited I thought. I have a powder (nitrofurazone) from Agrilabs that has an expiration of 2001 and I can't find this on the market either. I used it once on a calf a couple years ago and it was effective. We run black Angus cattle and don't have pinkeye problems until a recent outbreak. Does anyone know of an effective treatment like I used to be able to give?
