Goats' milk is better than cows' milk

For most people there is no advantage in drinking goats' milk. There are a number of nutritional differences between goats' milk and cows' milk but the difference is not likely to be significant for most adults. However, for infants under 12 months, goats' milk is unsuitable as a substitute for breast milk unless it is pasteurised and supplemented with the B group vitamin, folacin, and possibly vitamins B-12, C and D, to the levels present in human milk. Prior to the 1950s bottle-fed babies were usually given cows' milk diluted with water and containing added sugar or lactose. Babies fed solely on cows' milk modified in this way required additional vitamin C and iron. These days, a variety of nutritionally complete formulas based on cows' milk are widely available.

The effectiveness of goats' milk as a means of avoiding cows' milk allergy depends on which of the protein components in the cows milk is responsible for the allergy. Some components are common to both milks. If one of these components caused the allergy then substitution of one milk for the other would not overcome the problem. However, if one of the protein fractions occurring only in cows' milk was responsible for the allergy, then a change to goats' milk would be beneficial.
