Differs in what damn way? Unless it's a different enatiomer (R- vs L-) it's going to be the same molecule.

Edit: just looked it up, Lactoferrin is a glycoprotein produced in the human body that has antimicrobial properties and plays a role in immunity. It's commonly found in milk (including cow milk) and it's presence in mother's milk helps protect infants while they develop their own immune system. I'm sure we could find dietary ways to boost our own production.
