Goat's milk could be a key to addressing childhood mortality in developing countries.
A new study shows drinking it promotes a much speedier recovery from diarrhea.
The goats' milk contains an antimicrobial protein found in human breast milk, but not in cow's milk.
It's effective against bacterial infections in the gastro-intestinal tract.
Researchers say delivering milk in powdered form could be a cost-effective way to combat such child deaths.
