Normally sufficient immunity will be gained by the foal nursing and
the mare’s colostrum will have enough antibodies or immunoglobulins or
IgG. Foals should have either nursed colostrum from the dam or been
given a colostrum replacement within twelve hours of birth. If foals
cannot nurse successfully then a veterinarian may have to administer
colostrum by a nasogastric tube. For up to two years, colostrum can
remain frozen. Either through the Internet or locally at large breeding
farms you will be able to find frozen sources of colostrum.
