Listen to the experts on here (I am not one of them). They will tell you exactly what you need to do. But, when it comes to grain, too much is worse than too little as long as he has plenty of forage.Thank You.. him going on 4months, I'm thinking of switching feed to PURINA Pre Con Comp until 6 months.. I got that Beefmaker before doing some research since I just wanted to feed something right away.. See the problem is that I don't know at how many months did they weaned him from mother.. I'm just worried he didn't get enough milk, and I'd like for him to fully develop.. Any advice?
