Here are a few notes from old Lactnet digests. For more info, please do
search on this. I believe there are a few more notes there. This is for
information, and not to engender conflict. Everyone is welcome to learn and
take what fits for them.

Subject: Composition of milks
Here is information on the composition of human milk, goat milk, and cow
milk.
Human milk composition: Energy=700 kcal/L, Protein=9 g/L, Fat=42 g/L,
Carbohydrate=73 g/L, Calcium=280 mg/L, Phosphorus=150 mg/L,
Sodium=150 mg/L, Chlorine=400 mg/L, Potassium=580 mg/L,
Magnesium=30 mg/L, PRSL=93 mosm/L.
Goat milk composition: Energy=685 Kcal/L, Protein=34 g/L, Fat=41g/L,
Carbohydrate=45 g/L, Calcium=1205 mg/L, Phosphorus=1020 mg/L,
Sodium=415 mg/L, Chloride=1540 mg/L, Potassium=1845 mg/L,
Magnesium=130 mg/L, PRSL*=339 mosm/L.
Cow milk composition: Energy=627 kcal/L, Protein=32 g/L, Fat=35 g/L,
Carbohydrate=46 g/L, Calcium=1150 mg/L, Phosphorus=910 mg/L,
Sodium=515 mg/L, Chloride=970 mg/L, Potassium=1400 mg/L,
Magnesium=96 mg/L, PRSL=298 mosm/L.
Sources: Goat & Cow milk: Fomon, Samuel J. "Nutrition of Normal
Infants", 1993. Human milk: Riordan & Auerbach, "Breastfeeding and
Human Lactation", 1993.
According to several infant nutrition references, goat milk contains
inadequate quantities of iron, folate, viatmins C and D, thiamin, niacin,
vitamin B6, and pantothnic acid to meet and infant's nutritional needs. (I
did not compare those nutrients here, because the different sources
listed them in different reference amounts and I didn't have time to
convert them. If anyone wants the raw numbers, let me know) Of most
concern, is that goat milk has a high potential renal solute load (*PRSL)
that may cause kidney problems. We should consider that the severity
of the potential problems of consuming goat milk is dependent on the
amount of supplement given v. the amount of human milk consumed.
And, of course, this doesn't address all of the other beneficial
components of human milk that cow milk, goat milk and formula do not
contain.
