Your Foal's Health

Dr. Martin Adams, Equine Nutritionist for Southern States

Chances are your foal will sail through the baby stage with flying colors, especially if he is normal at birth and good management practices are in place at your farm.  However, even under the best circumstances, it's possible that your youngster could fall prey to one or more problems that can affect foals.  How does a healthy newborn foal appear?

Healthy newborn foals should:

  • Assume a sternal position (be able to sit up on his chest) within minutes of delivery.
  • Breathe easily, slowing from an initial high of about 70 breaths per minute to 40 to 60 minutes within 15 minutes of birth.
  • Have red or at least pink mucous membranes, indicating adequate oxygen is reaching the tissues.
  • Display a strong suckle reflex within two to 20 minutes of birth.
  • Appear alert and display an affinity for the dam.
  • Be able to stand within two hours and nurse within three hours.

If your foal fails to meet these criteria, he may already be suffering from a serious condition and needs the prompt attention of a veterinarian.

Good observation coupled with prompt action gives you the best opportunity to help your foal avoid a setback.  Following is a Foal Health Watch Guide that describes signs of a variety of common ailments that can occur during the first 6 months of a foal's life.  In most cases, even if the problem is not life-threatening, you will still want your veterinarian to confirm the diagnosis and direct you in the most effective treatment.  Please keep in mind this guide lists signs that are frequently observed with a certain disorder in a foal, but not all foals display the same signs or to the same degree.    A foal's condition can deteriorate very rapidly, so don't wait until your sick baby shows all the signs before taking action and calling your veterinarian.

Make every effort to maximize the chances of your foal's continued good health.  These good management practices can make the difference between a healthy foal and a sick one:

  • A well-ventilated, clean foaling environment.
  • Good farm and stable hygiene and parasite control.
  • Sound nutrition, current vaccinations and regular deworming of all equine residents.
  • Plenty of fresh air and room to exercise for the foal as well as commencement of a regular vaccination and deworming program.

Gently clean foal's tail and buttocks with soapy water to prevent scalding of skin

 

Dehydration, scalding of skin on buttocks, matting of tail

Fluids, decreased rations, clean tail and buttocks as above

 

Rapid dehydration, scalding, matting, fever, depression

Infectious diarrhea

Antibiotics, fluids, clean tail and buttocks regularly

 

Colicky

Colic after ingesting first milk, enema ineffective

Closed colon or rectum - development error causes gut to end in blind pouch

Surgery, success depends on length of missing part

 

Rolling, thrashing, lying on back, fecal matter not passed

Severe constipation, fecal mass too large or too far forward for enema to be successful

Laxatives, fluids

 

Lethargy, appetite loss, diarrhea, teeth grinding, lying on ground with feet in air

Confirm with endoscopy, treat with anti-ulcer medication

 

Profuse watery discharge from eyes

Blinking, avoidance of light, scratched cornea

Failure of passive transfer, foal did not receive adequate colostrum or was unable to absorb IgG

Provide colostrum if foal less than 24 hours old, otherwise administer plasma IgG transfusion

 

Greater than 400 mg/dl, low risk environment

Partial failure of passive transfer

Foal probably adequately protected, but watch closely

 

Less than 800 mg/dl, high risk environment

Partial failure of passive transfer

Administer plasma IgG transfusion, monitor IgG level

 

Weakness, incoordination

Delivery between 300 and 320 days of gestation, low birthweight, little or no suckle strength, weak fetlocks and lax pasterns

Premature birth

Oxygen, humidity and temperature control, tube feeding, fluids
