§ University tested

Colostrum - The Elixir of Life
Colostrum is the thick, sticky yellow fluid produced by the mammary gland of the mare during
the last few weeks of pregnancy.  Colostrum is rich in antibodies that are critically important
for immune protection of the newborn foal.  Foals are born without any antibody protection and
are entirely dependent on antibodies from colostrum for protection against infection during the
early neonatal period.
Most foals will stand within one hour and begin to nurse within 2 hours after birth.  Specialized
enterocyte cells in the small intestine engulf droplets of colostrum and transfer the antibodies
into the lymphatics and subsequently into the bloodstream.  The capacity of the small
intestine to absorb and transfer antibodies is greatest during the first 6 to 8 hours after birth,
declines substantially after 12 hours, and completely ceases within 24 hours after birth.  Foals
need to ingest a minimum of 1 to 2 liters of good quality colostrum within the first few hours of
life to acquire sufficient antibodies to protect against infectious diseases.

Failure of Passive Transfer

Failure of passive transfer (FPT) occurs in 10 to 20 % of newborn foals.  Inadequate passive
transfer of antibodies from colostrum puts a newborn foal at significant risk of infectious
diseases early in life.  The most common causes of FPT are premature lactation, poor quality
colostrum, failure of colostrum production, inability or lack of desire by the foal to nurse,
prematurity, dysmaturity, foal rejection by the mare, and failure to absorb antibodies that are
Refractometer evaluation of colostrum is valuable in determining the quality of colostrum to be
harvested and stored in a colostrum bank.  Owners and farm managers are strongly
encouraged to maintain a supply of equine colostrum frozen at -20° C.  A volume of 250 to 500
mls of colostrum may be safely harvested from a postpartum mare without adversely affecting
passive transfer to her own foal.
