My cow needs milk advice

Milk feeding advice for a cow depends on whether you mean a calf or a milking cow. For a calf, give colostrum in the first two hours, about two to four liters, then transition milk for three to five days. For a milking cow, focus on clean water, good green fodder, dry fodder, and balanced concentrate. If you want exact quantity, tell me her milk yield and stage of lactation.
