First post. :tiphat: Have to jump in on this one. I'm in the west central part of Kansas and pink eye is terrible here this year. According to me veterinarian, it's a wide spread problem. I used an autogenous vaccine, Long Range and fly tags. I've kept out a custom mixed mineral and the cows have consumed 3.5 ounces a day. 150 lbs every 10 days. I'm on my 4th bottle of Draxxin and have lost count of the darts. I have a PneuDart air rifle and it's been an eye-saver. 34 pairs here at the house and they've had it bad too. I've been able to bring them in and use the chute so it's been LA300 or ResflorGold for them. I visited with the feed mill that mixes my mineral and we've upped the Vitamin A. Our summer has been hot and awful humid and really expensive. :bang:
