Breast Milk Still The Best.

A breast feeding public reminder is being run on TV. The message goes like "a cow's milk is for a calf and same applies with the other mother-baby animals". So this should also go with human beings..that breast milk is for babies and not infant formulas which are commonly made from cow's milk. This got me thinking and wonder how do they alter a cow's milk to resemble that of a breast milk. I bet they're very carefully done so as not to include the effects of cattle supplies and chemicals took in by the cow.
