[YEA] Sea kelp will get rid of pink eye. I had 5 steers, all with pink eye. Took them to the vet, he gave them a shot of something in the eye (very painful) took them home, 4 got better but 1 got pink eye again. Took him back to the vet and he gave him the treatment again and said if this doesn't work, then he will have to go blind. It did not work. My friend suggested that I give them sea kelp, which I did. I gave it to them free choice and within 5 days his pink eye was completely gone. For livestock, I bought in 50 lbs bags from a company in Maine. From what I understand, pinkeye is a lack of minerals.
