I don`t think you can get that kind of ADG from bulls with that formula. In my experience you will have to add maybe say corn for added energy & soybean meal to reach 3.5 lb. or at least in my area this is average mix you would feed.Then again depends on breed of cattle you are growing. Lots of idea`s out there but, i can`t reach that gain with hay & soyhulls.
