Title: Lactoferrin for Prevention of Sepsis in Infants
Brief Summary: The investigators propose a clinical trial in premature infants to determine the effect of orally-administered bovine lactoferrin on occurrence of severe infections and to determine whether as a result of decreased infections, infants' growth and development improve after daily lactoferrin supplementation, due to its antimicrobial and anti-inflammatory properties. If successful, the use of lactoferrin as a protective protein could profoundly affect clinical care of neonates both in the developed and developing world.
