>> Baby cows don't drink pasteurized milk, and neither do human babies

> No, but (a) there's a much shorter supply chain there in nature, which is the big problem, (b) cows consume all sorts of things that are inedible by humans, and (c) it's not actually "natural" for humans to drink cow's milk at all, that's a relatively recent genetic adaptation (lactose tolerance) that not everybody has.

and (d) some places, especially large dairies, do feed baby cows pasteurized milk. They do this to limit the spread of illness among their livestock and to use up waste milk. Some do this with colostrum as well.
