Passive Transfer of Immunity in Foals:
Assesment and Treatment of Failure of Passive Transfer
  by Robert N. Oglesby DVM

Introduction

Foals must have adequate amounts of good quality first milk, called colostrum, within 12 hours of birth to remain healthy. Unlike most newborns, foals are born without any antibodies (immunoglobulins) to fight infection. He gets these first antibodies from the colostrum and we call this process of the mare transferring antibodies to the foal, passive transfer. Though debate about what constitutes adequate levels of antibodies in the newborn after passive transrer, one thing is certain, without some passive transfer the foal will develop infections and die. This article discusses colostrum and passive transfer in greater detail, testing for passive transfer, and treatment for it. See also Feeding Orphan Foals.
