96. Myth or Real? NI (Neonatal Isoerythrolysis) is a preventable disease in the horse.

Answer: REAL
In a webinar given on 2/7/18 by Ghislaine Dujovne, DVM, MS, DACT, of UC-Davis, the topic as addressed in a very thorough and straightforward way. She approached it by
explaining what this issue is, how it happens and what can be done to prevent its
occurrence. We all understand the old saying “an ounce of prevention is worth a pound of
cure” and certainly preventing NI is a much better option than trying to treat an affected
foal. This webinar is well worth the time to watch and it will be archived in its entirety on
the FHANA website. I highly recommend that you set aside the 1 ¼ hour it will take to view it. You will learn something valuable and knowledge is power!

  • Blood type your mare. Well worth the $$ and a comparison of her blood type with that of the potential stallion that she is to be bred to can either prevent the possibility of NI altogether OR help one to prepare properly for the possibility of producing a foal that may have this issue.
  • The incidence of NI seems to be higher in the Friesian breed but may not be related to an inbreeding issue. The answer to this question of a higher prevalence may require additional research to come to a conclusion.
  • NI can occur even with a maiden mare, although it is less likely.
  • There are several tests available to diagnose a foal showing the clinical signs of NI.
  • There are also ways to test the colostrum/milk post foaling to determine when it is safe for the foal to begin nursing the mare.
    Thank you to the FHANA Education and Health Committee for sponsoring this webinar and much appreciation to Dr. Dujovne for taking the time out of her busy schedule to present it.
