Tracy:
Adopted infants whose adoptive moms can't lactate or who can't receive donor
human milk should get one of the commercially available formulas.  I would
vote for using one of the standard cow-milk based formulas such as Enfamil or
Similac, as there are some significant concerns with soy-based products and
the elemental formulas are very, very expensive and not necessary for most
babies.  Goat milk is deficient in several important nutrients and even less
like "mom's own" than the commercial formulas--whole goat milk is no more
appropriate for human infants than is whole cow milk.  At least the formulas
are actually based on current understanding of infant nutritional needs, and
babies will generally do OK with them.
