Am I wasting my money to feed Vitaferm Concept Aid cubes if I am already using their concept aid minerals? Also has anyone had experience using of the pro-gest, vitaferm formula, or digest more pellets in their creep feed? I am thinking this would be a great addition to a creep ration but wanted to see if anyone has tried it. And finally has anyone used their milk-n-more milk replacer and if so what did you think?
