Goat milk or goat colostrum is inappropriate for infants for the same reasons
that cow's milk is inappropriate: allergenicity, high renal solute load, low
levels of iron and folate, etc.  See the position paper of the American
Academy of Pediatrics on The Use of Whole Cow's Milk in Infancy. Pediatrics
89:1105-1109;1992.  and:  AAP recommendation on cow's milk, soy and early
infant feeding by Scott, FW in Pediatrics 96:515-517;1995.

Some contend that goat's milk is less allergenic than cow's milk but I have
yet to see research validating this.  I refer you to: In Vitro Allergenicity
of Cow's Milk Substitutes by Dean, TR et al. Clin Exp Allergy
23:205-210;1993.  and:

Breastmilk and Special Formulas in Prevention of Milk Allergy by Bahna SL.
Adv Exp Med Biol. 310:445-451;1991.  and:

Comparison of bovine, Sheep and Goatmilk Lactoferrins in Their
Electrophoretic Behavior, Conformation, Immunochemical Properties and Lectin
Reactivity. by Shimazaki K, et al. Comp Biochem Physiol 98:417-422;1991. and:

Diet and the Prevention of Childhood Allergic Disease by Cant AJ. Human
Nutrition/Applied Nutrition. 38:455-468;1984.

In addition to the allergenicity of goat's milk proteins, the much-higher
levels of protein and sodium in goat's milk compared to breastmilk (or ABM)
contribute to goat's milks higher renal solute load which makes it hard on an
infants' kidneys. Goat's milk has about 1.1 grams protein per ounce while
breastmilk has just 0.3 grams per ounce.  Goat's milk has about 15 mg sodium
per ounce while breastmilk has just 5 mg per ounce.

Iron is another concern.  Breastmilk contains about 0.7 mg iron per ounce.
 In contrast goat's milk has only about 0.02 mg iron per ounce.  Goat's milk
is also extremely low in folic acid.

We know that homemade cow or goat milk formulas are inferior to ABM.  As for
ABM, it cannot come close to breastmilk, it is made by multinational
corporations with questionable ethics, and it stinks, but ABM is still the
best second choice for human babies that there is. Goat's milk was made for
baby goats.
