I am finishing a steer and a young bull to be processed. They have been on a grow/commodity mix for the last couple of months. Since I am about 3 months out from my processing date, I switched them to WSC. I admit that I was probably trying to push them too hard and I did not realize the difference that the switch would make and they developed acidosis. I have withheld all grain and have been giving them bicarbonate soda with their salt a mineral. They seem to be improving and their manure is starting to tighten back up. My question is, how long should I wait before I start reintroducing the grain?
