It depends on what purpose you have for these calves, and what you wish to feed them. But really, you just start feeding them, start training them to eat whatever you set out for them, and let their curiosity get the best of them and get them interested in eating what you've set out for them to start eating. But, it's best to feed them what you have been feeding them prior to weaning, and continue feeding them this, slowly switching over to what you are intending to feed them in the first place.
Mode of feeding is how you would be fed should you not be able to feed yourself. Feeding tube, intravenous, etc.
