The Foaling Process


Most mares foal without difficulty, and are best left alone to foal unassisted as you watch from outside the stall.  Unfortunately, when things do go wrong it happens rapidly and often with life-threatening consequences to both mare and foal.  The best preparation for the abnormal is to know the normal. Here are the normal stages of labor, with notation when to CALL THE VET!

First Stage Labor

The mare has some control over first stage labor, and it can last intermittently for several days.  Signs include restlessness, circling, getting up and down frequently, but no obvious strong contractions.  If there is any doubt in your mind whether you are observing first stage labor or something abnormal,  don’t hesitate to contact your veterinarian to discuss your observations.

Second Stage Labor

Second stage labor involves the actual delivery of the foal.  In the horse this is a very rapid event.  Once the mare is exhibiting strong contractions and her water has broken, the foal should be on the ground within 30 minutes.  In a normal delivery you will see two front feet, one slightly ahead of the other, followed by the foal’s nose, head and neck.  The mare may get up and down several times during second stage labor, and will appear quite distressed.  Some mares may deliver their foal standing.

If more than 20 minutes has passed after the onset of strong contractions and delivery is not complete, CALL THE VET.

Third Stage Labor

Third stage labor involves passage of the placenta.  During this period the foal will be struggling to rise, standing, and making attempts to nurse.  The mare may show signs of abdominal cramping (colic) as her uterus begins the rapid process of contracting to expel the placenta.  The placeta should be passed within two hours of the foal’s birth.  Save the placenta in a bucket covered with water so that it can be examined during the foal’s post-natal exam.

If the placenta is not passed within 2 hours of delivery, CALL THE VET.

The Newborn Foal

A normal newborn foal will attempt to roll up on his/her chest and shake his/her head almost immediately upon delivery.  Initial attempts to stand should begin within 10 minutes and the foal should be standing within 30 minutes and nursing within 2 hours.

If the foal is not standing within 30 minutes, or is not nursing within 2 hours, CALL THE VET.

The foal will pass black, grape-like clusters of manure (meconium) for the first 12 hours, then manure will transition to a soft pasty, orange manure.  The normal foal will nurse about once an hour, wander around a bit, then lie down and spend most of his/her time sleeping.

Your Post-Delivery Jobs

Assuming your foal is delivered without complication, you should dip the umbilical cord in dilute chlorhexidine or 2% iodine within 30 minutes of birth.  Do not cut or tie the umbilical cord, rather allow it to break on its own.  When the placenta passes, collect it and save it in a bucket.  Once the foal is up and nursing by 2 hours, give everyone a hug and a smile, and CALL THE VET to schedule your foal’s post-natal exam, which should happen when the foal is 18-24 hours old.  It is critical to confirm that your foal has consumed adequate colostrum (the mare’s first milk) which contains essential antibodies.  This will be confirmed during the post-natal exam with a stall-side blood test, and a full physical examination of the mare and foal, as well as placental evaluation will be performed.

Smoke and Your Horse

 Smoke is an unhealthy combination of carbon dioxide, carbon monoxide, soot, hydrocarbons, and other organic substances. Smoke particulates can irritate horses’ eyes and respiratory tracts, and hamper their breathing.

The simplest thing you can do to limit the damaging effects of smoke on your horse’s airway is to limit your horse’s activity when smoke is visible.   Increased airflow and turbulence that accompany athletic activity can significantly increase the inflammation and damage to delicate cells lining the respiratory tract. In addition, if possible, misters and fans can be used to improve air quality in your horse’s environment.

Human air quality advisements can be applied to your horse as well.  If your eyes are burning and you smell and taste smoke, then assume that your horse is feeling as uncomfortable as you are.

Most importantly, when smoke has been particularly heavy, remember that it takes time for airways to recover fully. Four to six weeks can be required for airways to recuperate from severe smoke exposure, and early return to exercise can delay healing and increase the risk of long term airway damage.

 The best way to combat heat and smoke is through hydration. You can:

  1. Provide clean, fresh water at all times
  2. Water your horse’s hay and feed grain as wet mashes
  3. Put sprinklers out in turn outs to reduce dust and smoke and increase moisture in the air

 


Balance, Conformation and Performance

 

Over the years we have bred horses to be balanced to best suit their intended use.  When you choose a horse, consider your equestrian discipline. 

 

Draft horses were built to pull – they are very “uphill” with short, strong high set necks, powerful shoulders and weaker hindquarters.

 

Quarter horses are built to work cattle – they need to keep their heads low and turn with exceptional speed and quickness from the hindquarter – therefore they are quite “downhill” with tremendous power in the sacrum, hip and thigh to dig in, turn and go.

 

Thoroughbreds are built to run – they are a more level breed, but frequently have a croup that is slightly higher than the wither.

 

The arab is the ultimate long distance athlete – generally beautifully balanced front to back, but with lean muscle mass and a relatively straight shoulder, making them extremely efficient at moving across the ground, but not well suited to elevating the wither or forearm.

 

The warmblood breeds have been developed to have a combination of elevation and length.  They are balanced generally uphill, with a neck that comes out of the wither relatively high, a moderately sloped shoulder, and a very powerful sacrum and pelvis.

 

And don’t forget, the horse in motion always trumps the horse standing still.  For example, consider a “downhill” quarterhorse with contracted heels in front but a strong, symmetrical, well conformed pelvis and hind limbs.  The contracted heels and forehand balance  may predispose this horse to foot lameness.  However, if the horse is trained to move with impulsion from behind, raise the withers and engage the core, this will result in an overall “lighter” movement, and reduce concussive force on the heels.  The result: forelimb lameness resulting from imperfect conformation may be avoided.

 

Your horse’s overall balance is extremely important in maintaining athletic longevity and compensating for conformational defects in the lower limbs.  However, training that develops excellent core strength and flexibility can greatly enhance the horse with less than ideal balance.  Here is the bottom line: stand back and look at the whole picture, the entire horse, not just the offset knee, or base narrow stance, or turned out toes.  If you develop your horse’s entire body to be strong at the center and balanced from front to back, you will successfully overcome the majority of his/her conformational problems.

Understanding Influenza & Immunity

Equine influenza shares many similarities with the human flu virus that has been particularly brutal this year.  The equine virus exists worldwide, except in New Zealand and Iceland.  Clinical signs include fever, depression, poor appetite, cough and nasal discharge.  The virus only lives a short time in the environment and is susceptible to common disinfectants.  In most cases the virus is spread from horse to horse in aerosolized particles generated when an infected horse coughs.  Unfortunately, virus replicates in the horse’s upper respiratory tract and is shed into the environment for a few days BEFORE any clinical signs become apparent, making control of disease outbreaks challenging, especially in larger groups of horses.
The virus has many serotypes, and these strains change frequently.  The horse must have antibodies specific to each serotype to prevent disease.  I imagine the flu virus as a secret agent – every time he appears he is wearing a different hat and coat so I don’t recognize him until it is too late and I have already walked up to say hello and shake his hand…..and a few days later I am coughing and sneezing, or watching my horse cough and hang his head.  Both we and our horses manufacture antibodies that are shaped to fit the “hat and coat” of each flu strain that infects us – when exposed to a virus strain wearing a new “hat and coat” the old antibodies may not accurately recognize and attack the new virus and so we get sick all over again.  Don’t get confused here – while equine influenza virus and human influenza viruses share the same infection tactics, and do have antigenic similarities, so far horse to human transmission is not a clinical problem.  Equine Influenza has however caused serious influenza outbreaks in our canine companions.
Pharmaceutical companies making vaccines against Equine Influenza know that in order for their vaccine to be effective, it must contain the most up to date viral strains in a given location.  They weigh this against the cost of introducing new strains into their current vaccine.  The World Organisation for Animal Health global Equine Influenza Surveillance Program was initiated in 1995, and makes regular recommendations for the most current Equine Influenza strains to be included in vaccines.  The Merck influenza vaccine used in our practice (Prestige 2) contains Equine influenza virus type H3N8 strains EIV A/eq/Florida/RW/13, EIV A/Equine 2/Kentucky/02 American, EIV A/eq/Richmond/1/07 strains. Merck and UC Davis co-sponsor the ongoing Equine Respiratory Biosurveillance Study.  The Influenza strains included in Prestige 2 are based on this study, and include the Florida ’13 Clade 1 highly pathogenic isolate identified in the Ocala 2013 outbreak.
There may be some of you reading this thinking, “well I got my flu shot and still came down with the virus, why should I vaccinate my horse?” My answer is this: vaccination against Equine Influenza does not guarantee protection from disease, but it can dramatically reduce the incidence and severity of illness.
      Consider any population of horses with stressors such as competition, travel, breeding, changing populations. If ALL of the horses in such a group are vaccinated against influenza the consequences of infection with flu virus are greatly reduced.  Although equine influenza vaccines may not be absolutely protective, they do reduce the virus’ ability to replicate in each horse, and therefore reduce the number of virus particles released into the environment and passed from horse to horse.  If EVERY horse in your barn is vaccinated, when Equine Influenza enters the population the viral load in the vicinity is kept low, fewer horses actually contract disease, and the outbreak event is over much sooner, with fewer sick horses.  
 On the other hand, if all the horses is a population are not vaccinated at the same time and on a regular schedule, the vaccinated individuals may have sufficient immunity to protect them from showing signs of disease but may still contract a mild flu infection and shed low numers of virus particles.  The unvaccinated, or poorly vaccinated horses in the population, especially the young and old, then serve as living incubators for the virus shed by vaccinated horses.  The result is often a more severe and prolonged disease outbreak moving slowly through the barn. Horses, especially younger ones, living in groups without diligent vaccination, rapidly spread virus from one to another making it very difficult for humans in charge to stay ahead of disease spread.  In larger barns, the outcome is usually quarantine of the entire facility for 21 days or longer, or until 7 days after the last horse has any clinical signs or fever.   As you can imagine, such an outbreak has serious impacts, both on horses’ health and humans’ pocketbooks. The risk of pneumonia and other serious complications increases dramatically in such settings.
So, the bottom line regarding influenza vaccines in horses is this: all horses in boarding facilities, and/or horses that travel to competitions, should receive an influenza (typically as a combined “flu/rhino” vaccine) every 6 months.  The United States Equestrian Federation requires proof of flu/rhino vaccination within 6 months at all registered equestrian events.

Summer Sores

What are they?

Your horse’s eyes are red, swollen and itchy, or there is an odd sore at the corner of her mouth, or a wound on her pastern that is getting larger and lumpier….all common presentations of Habronemiasis, or Summer Sore. If left untreated, this common problem can become an extremely challenging condition to resolve.

Summer sores are caused by stomach worm larvae deposited in wounds by stable or house flies.  Larvae licked up and swallowed by horses complete their life cycle in the intestinal tract (where they do little harm), but when stranded in broken skin they cannot mature and cause severe, chronic inflammation.  The result is a non-healing, expanding wound.

Treatment involves immune-suppressive medication (steroids), destruction of larvae (dewormer) and surgical removal of the larvae, proud flesh and granular inflammatory deposits from the lesion.  I surgically excised the summer sore from this horse’s lip, sutured the wound closed, and applied Alu-shield spray to the wound and SWAT around the area.  The horse also received a carefully calculated dose of steroid, short-term antibiotics, and Ivermectin deworming.

Unfortunately, summer sores often are not recognized as something other than an uncomplicated wound until the disease process is quite advanced.  At this point successful treatment can take weeks, incur high veterinary costs, and require intensive wound management.

Habronemiasis has become a common problem in our area, and is often seasonally recurrent.  Preventive measures include frequent deworming, fly masks, and aggressive fly control.
             
Beware of Harmful Dentistry
I took this picture several weeks after this horse underwent aggressive motorized dentistry. This is NOT how your horse’s teeth should look after dentistry. Notice how the edges of the teeth are curved, the biting surface is smooth, and the front of the first premolar has been removed. In the short term, this procedure causes thermal damage and impairs the teeth’s ability to break down fiber, reducing the intestinal digestive enzymes nutrient processing.  And long term, it removes surface enamel from the tooth that CAN NEVER BE RESTORED.  Year after year of this procedure will reduce the life of your horses’ teeth, but the damage may not be show until it is too late to change the outcome.
            This is what your horse’s teeth should look like after correct dentistry, whether performed with hand tools or motorized tools.  Our understanding of equine oral health has come so far in the past decade, there is NO EXCUSE for “over-floating”.
       Annual dentistry is a vital part of LONG TERM health care. Don’t let your horse’s condition in later years be compromised by poor management today.  Foot care, nutrition, deworming, and DENTISTRY are the 4 corners of your horse’s longevity.  Ask me any questions at your fall clinic appointment.  An important part of my role in your horse’s life is to answer your questions and keep you informed.
