The Top 10 conditions found during your
annual equine health exam.
Even the healthiest of horses will see
their vet annually, this is often the time that they receive their
vaccinations and dentistry. In addition to this, your vet will also
examine your horse's body condition, heart, lungs and abdomen. The
head, body and skin are evaluated. A free of charge oral exam can be
completed and advise is given regarding nutrition, de-worming and
other management strategies for the year ahead. A manure sample can
also be collected for faecal worm egg count analysis, as part of your
targeted worming strategy.
The vets here at The Barn Equine
Surgery recently compiled a list of the top 10 conditions diagnosed
at annual health exams.
10. Eye conditions.
Uveitis is a term for inflammation
within the front portion of the eye. The condition may be
recognised by mild discharge from one or both eyes, the eyes being
held slightly closed or mild swelling of the tissue around the eye.
Equine Recurrent Uveitis, if left untreated, can lead to recurrent
episodes of pain and eventual blindness. It is important to
differentiate this condition from mild conjunctivitis that may be
caused by flies or tearing due to blocked nasolacrimal ducts (tear
ducts) that can be readily flushed by your vet.
9. Degenerative Joint Disease
You may mention to the vet that you
have noticed some increased stiffness when first riding your
horse. Arthritis becomes more common as the horse ages. Although
it is often a progressive condition, early diagnosis can lead to
prompt management changes that may prolong the soundness of your
horse and improve their comfort.
8. Dermatitis
Skin problems are often noted on
yearly examinations. Advise and treatment options can be provided
for conditions ranging from rainscald to sweet itch allergies.
Sweet itch can be differentiated from those animals that are
rubbing their tails due to pinworm and approprate treatment can
be implemented. Mud fever (pastern dermatitis) can be
differentiated from the more serious condition of pastern
leukocytoclastic vasculitis, a condition specific to white legs
that can extend up the pastern and include portions of the canon
region of the limb. This condition can have an immune mediated
element or be an early indication of photosensitivity.
7. Equine Asthma
Equine asthma, formerly known as
recurrent airway obstruction, can be detected whilst in the early
stages of disease, prior to performance limitation. This is an
allergic disease of the airway, often triggered by environmental
allergens such as mould spores, bacterial toxins, dust particles
and ammonia. Sensitivity to pollens can cause a pasture
associated asthma condition. Auscultation of the chest can often
identify early signs of disease and environmental, feed or
medical management can be implemented promptly.
6. Laminitis and hoof problems.
Many horses will develop
sub-clinical hoof changes before lameness develops. Wide white
lines, converging hoof rings, recurrent solar bruising and
increased sensitivity to riding over hard or uneven ground can
all be early signs of laminitis, that are found on annual health
exams. Poor hoof quality, conformation or conditions such as
thrush can also be addressed.
5. Dental conditions
A free of charge oral examination
with an oral speculum (gag) can be performed at your annual exam.
If dentistry is required then this can be performed. All horses
should receive an oral exam every year, a sedated oral exam should be performed at the very minimum of once every 2 years, to allow accurate use
of a dental probe and mirror to evaluate each tooth for signs of
infundibular decay or caries, abnormal occlusal wear patterns,
periodontal disease, crown fractures or disease of the dental
pulp. This sort of detailed examination can not be performed fully in an unsedated horse.
4. Cancerous lumps
Sarcoids are the most common skin
tumour of horses and are caused by bovine papilloma virus. Early
diagnosis and removal reduces the chance of the lesions seeding
around the body and improves the prognosis. Melanoma is a common
tumour of grey horses and can often be found under the tail,
around the mouth and infiltrating the parotid region of the
throat. The majority of melanomas are benign, however malignant
melanoma does occur and melanoma found in non-grey horses is
often more severe. The location and size of melanoma growths are recorded to allow accurate monitoring. Squamous cell carcinoma is
often found around the eye of horses lacking eyelid pigment, on
the third eyelid and in male horses around the sheath and penis.
This type of skin cancer can be easy to miss in the early stages,
prompt treatment will improve prognosis.
3. PPID (Pars pituitary intermedia
dysfunction) or Equine Cushings Disease.
This common endocrine disease is
more prevalent in older horses, although it can occur at any age.
A simple blood test can be used to screen for the disease and
during the summer season the laboratory fees are free of charge
for this blood test. The disease causes a reduced ability to
fight off infection, muscle loss, a pot belly appearance, delayed
shedding of the winter hair coat or the presence of guard hairs
and of course, laminitis.
2. Heart murmurs or arrhythmias
Heart murmurs indicate an abnormal
flow of blood through the heart, not all murmurs cause problems,
however ongoing monitoring is important to detect changes in the
status of the heart. This includes monitoring the rate and rhythm
of the heart to allow early detection of compromised heart
function.
1. Obesity
By far the most common health
condition detected on health exams, that owners are often not
aware of, is obesity. Obesity greatly increases the chance of
your horse developing laminitis, arthritis and colic. Increased
fat deposits are known to cause insulin resistance and are often
a component of equine metabolic syndrome. Blood testing for
insulin dysregulation is available and your vet can guide you on
your nutritional and exercise management. You may consider opting
for ongoing weight management with our Weight Wise Scheme.
