You can use it or not. I have never used it for scours. Just weak calves or calves that are stressed. If he is not either, then don't worry about it. Sometimes when they get into a new environment, they stress. I just figured that since you just got him, it might be a precaution you would want to take. I have raised a ton of bottle calves and worked for many years on a dairy farm and even use to show them. Just sharing a secret.
BTW - Congrats on the calf. Jerseys are my favorite.
