We are new calf owners. We brought home a 2 week old bull calf on Friday. He is a holstein. We have him on milk replacer and he is doing well so far. When should we start him on grain? We are offering hay, he is nosing through it at this stage. We raise goats as well. Can a calf be fed a mixture of 1/2 goat milk & 1/2 milk replacer (mixed with water already)? I would gradually change to this mixture, if it were compatable with a calf. I pasteurize the goat milk. My husband grew up with a herd of dairy cows but he was not involved with management, so he knows just about as little as I do. The calves were bucket fed milk straight from the cow. I want to make sure I keep this guy healthy, and I soon hope to bring home a holstein heifer calf. I think I am going to be hooked.
