Free choice sodium bicarbonate. If its truly pinkeye, there's a ph imbalance in the rumen allowing the pinkeye, as well as hoof rot etc, to get a grip. Excessive protein often leads to that imbalance.
YouTube video - remineralizing cattle with Steve Campbell. He speaks on this. Makes a lot of sense IMO.
Ive had 7 calves tale chicory stalks INTO the eyeballs. Talking about a good size hole. Never did become pinkeye. Healed up within a week and vision is fine.
Ive not had actual pinkeye in 4+ years.
I dont use it as my animals have a pretty balanced diet in terms of fiber and protein. When i started grazing at density those problems slowly disappeared. Only eye problems I have now are from stem pokes, which have yet to turn into pinkeye. (Knock on all the woods) Ive got a flock of birds that follow the cows around all the time and eat the flies. Im sure that helps with eye health as well.What is your method of "feeding" it? Do you follow the ways outlined in the video or mix it in your regular mineral?
My neighbor keeps the sodium bicarbonate in a mineral feeder, free choice. The kind with the rubber mat on top. Since doing so he had had zero pinkeye and honestly, the animals do look better. They give them entirely too much protein over there. Pinkeye has been a battle for them every year since 2018 or 2019 when they started.
Im the furthest thing from an expert youll find on this board but I do think the whole PH/pinkeye thing makes perfect sense. Therefore I try to share the info. There is quite a bit of content on YouTube with Mr Steve Campbell.
