A friend of mine states that a calf beyond age 3 months is not likely to be able to digest and use milk to gain wt. Personally, I dont think this is true. We weaned our last calf(Holstein) at 5 months as we had plenty extra to give him. At 6m he weighed 450# and did not start eating much hay and grain until 3m. Your thoughts? I'd hate to think I poured all that milk down his throat for wasted calories.
