Study Notes

Horse Management and Disease

Horse management practices often lead to diseases and injuries.
Horses are naturally designed for continuous foraging and movement for up to 16-19 hours per day and up to 60-80 km/day.
Horses are social animals and require contact with other horses
Horses need long stem forage to maintain a healthy gut. However, this is not always provided, especially when horses are used for performance.

Colic

Colic encompasses various clinical signs, ranging from gas pain to a strangulated intestine.
It is the leading cause of death in horses.
Symptoms include rolling violently, pacing, kicking at the belly, loss of appetite, and inability to pass gas or feces.
Prevention includes continuous forage, avoiding sudden diet changes, minimizing distress, hydration, and movement.
Treatment depends on the cause and may involve pain management and surgical intervention which has ~50% success rate.
Surgical cases have risks of complications.

Injuries

Injuries can be caused by unsafe fences, sharp objects, holes, rocks, casting against fences, inappropriate herd mates, performance activities, and training.
Treatment for injuries primarily involves rest and rehabilitation.

Equine Infectious Anemia (EIA)

This is a reportable disease to the CFIA leading to euthanasia, as horses carrying the disease are life-long carriers.
It is caused by a retrovirus that infects macrophages.
The incubation period is 1 week to 3 months, but typically 2-4 weeks.
The disease spread through biting insects and reused needles.
It is often triggered by stress.
Horses can experience temporary recovery, but then relapse
EIA can be contagious symptom-free.
A vaccine is available, but cannot be used for horses in the United States.
Clinical signs include anorexia, depression, general weakness, fever, jaundice, small hemorrhages under the tongue and eye, swelling of the extremities, and weight loss
A Coggins test detects antibodies for the EIA virus. It is required for most performance activities and cross-border transport.

Strangles

Also known as horse distemper, it is an upper respiratory disease caused by the gram-positive bacteria Streptococcus equi.
Horses can shed bacteria for up to six weeks after clinical signs disappear, or become lifelong spreaders of the disease.
The disease spreads through direct contact or environmental contamination.
Horses are contagious before symptoms appear.
The bacteria infects lymph nodes; symptoms include fever, nasal discharge, swollen lymph nodes, and abscesses.
The available vaccine has limited effectiveness.

Eastern Equine Encephalomyelitis

This is an uncommon but frequently fatal disease that causes brain inflammation.
The virus has an incubation period of 2-3 weeks, followed by 2-3 days of clinical signs.
The virus is mosquito-borne and is a member of the RNA enveloped virus family.
Most horses die within 2-3 days.
90% of horses with the disease die.
The disease can be diagnosed by IgM antibodies to the virus.
There is a vaccine available, requiring an annual booster.
The disease can be zoonotic.

Contagious Equine Metritis

Caused by the gram-negative bacteria Taylorella equigenitalis, this is a bacterial infection of the uterus.
The disease spreads through sexual contact.
Clinical signs appear ~10 days after breeding.
Infected mares can be either symptomatic or asymptomatic.
Causes abortion and uterine inflammation.
Active infections in mares can be treated with antibiotics.
Stallions should be cleaned with 4% chlorhexidine before breeding to prevent the spread of the disease.

Equine Protozoal Myeloencephalitis (EPM)

This disease is caused by the protozoan Sarcocystis neurona.
It is spread by opossums, cats, skunks, and raccoons.
The disease causes severe neurological signs.

West Nile Virus

This is a mosquito-borne RNA virus that infects birds.
The virus can cause neurological signs and fever, but can also be asymptomatic.
It is zoonotic, but causes disease in only ~20% of humans.
There is an effective vaccine, but no treatment.

Deworming

Misinformed owners who alternate dewormers, deworm too often, or maintain unhygienic conditions can contribute to the development of antihelminthic resistance.
Solutions include fecal egg counts, deworming based on the presence of parasites, and maintaining a clean environment.

Horse Owners

Horse owners often view horses as athletes, workers, or livestock, rather than pets.
Horses do not always receive immediate care for illness or injury.
Limited care and treatment may be due to the financial limitations of owners.
Misinformation regarding horse care is common.

Dental Care

Horses develop their full set of adult teeth by ~5 years old.
Teeth grow continuously and are naturally offset from each other.
"Floating" teeth is required 1-2 times per year to eliminate sharp edges and uneven wear, improving eating and reducing skin lesions.
Horses should be sedated under veterinary supervision.
Wolf teeth and "caps" may require removal.
Fractured teeth and abscesses can develop.
Signs of dental issues include "quidding", uneven chewing, dropping feed, and weight loss.

Hoof Care

Hooves should be trimmed and balanced at 6-8 week intervals.
Hoof angle can affect lameness and future arthritis development.
Abscesses are common in unsanitary conditions.

Laminitis

This is an extremely painful condition of the feet, in which the lamina (the tissue that attaches the hoof to the bone) becomes inflamed.
Symptoms include stiffness, sawhorse stance (weighing on hindquarters), weight shifting to the hind legs, an increased digital pulse, and hot feet.
The condition is diagnosed through radiographs.
Laminitis is often caused by metabolic diseases (such as PPID, or Cushings), obesity, high-starch diets, immune hypersensitivity, infection, toxins, compensatory limb laminitis, and injury.
One of the leading causes of death in horses.
Managing the underlying condition, surgical intervention, and therapeutic trimming/shoeing are important for treatment.

PRP (Platelet Rich Plasma) Injections

PRP is a regenerative medicine treatment that uses a concentrated solution of platelets drawn from the horse’s own blood to help heal tissues.
Platelets supply growth factors, which stimulate healing in tissues.
It can be used to treat a variety of conditions including soft tissue injuries, joint problems, and laminitis.

Stem Cell Therapy

Stem cell therapy uses a patient's own stem cells to promote tissue regeneration.
They are undifferentiated cells that have the potential to turn into any type of cell, making them ideal for healing tissues damaged by injury or disease.
Stem cell therapy can be used to treat various conditions, including bone and joint problems, muscle injuries, and tendon injuries.

Steroid Injections

Steroids can be used to reduce swelling, pain, and inflammation, particularly in joints.
Steroids are powerful anti-inflammatory drugs that inhibit the body's immune response, which reduces swelling and inflammation and helps with pain management.
Steroids are commonly used to treat a variety of musculoskeletal conditions in horses, like tendonitis, bursitis, and arthritis.

Shockwave Therapy

Shockwave therapy delivers acoustic waves to promote healing and reduce pain.
The shockwaves are delivered to the injured area, stimulating the body's natural healing process, to break down scar tissue, encourage blood circulation, and reduce inflammation.
Can be used to treat a variety of musculoskeletal conditions including tendonitis, bursitis, and arthritis.

Chiropractic Treatment

Chiropractic uses manual manipulation to correct misalignments in the spine to reduce pain and improve mobility.
Can be used to treat a variety of musculoskeletal conditions in horses, including back pain, neck pain, and lameness.

Acupuncture

Acupuncture uses needles to stimulate specific points on the body to relieve pain and improve function.
It is often used to treat pain associated with musculoskeletal conditions, such as arthritis, back pain, and lameness.
Can also be used to treat conditions such as colic and respiratory problems.

Magnetic Wave Therapies

Magnetic wave therapy uses magnetic fields to stimulate healing.
Supporters claim these therapies can reduce inflammation, improve circulation, and stimulate cell regeneration.
Can be used to treat a variety of musculoskeletal conditions, including tendonitis, bursitis, and arthritis.

Surgery

Surgery is a last resort for treating many conditions but is often needed to address serious injuries or diseases.
Surgery is a major procedure that requires careful planning and consideration, including potential risks and benefits.

Equine Management & Disease

Management impacts health and welfare: Horses are naturally designed for extensive foraging and movement, but management practices often contradict this, leading to health issues like colic and injuries.
Colic: A broad term for abdominal pain in horses with varied causes. It's a leading cause of death due to various clinical signs like rolling, pacing, and lack of appetite. Prevention includes continuous forage, avoiding sudden diet changes, proper hydration, and movement.
Injury: Horses can get hurt from unsafe fencing, sharp objects, inappropriate herd mates, and performance activities.
Equine Infectious Anemia (EIA): A reportable disease that can be fatal and results in lifelong carrier status. EIA is a retrovirus that invades macrophages, causing various symptoms like fever, jaundice, and weight loss. It's spread by biting insects and contaminated needles.
Coggins testing: A blood test required for many equine activities to detect antibodies to the EIA virus.
Strangles: A serious upper respiratory infection caused by Streptococcus equi. The bacteria can be shed for weeks after clinical signs, leading to long-term spread.
Eastern Equine Encephalomyelitis (EEE): A rare but often fatal virus that causes brain inflammation. It has severe neurological signs and is spread by mosquitoes.
Contagious Equine Metritis (CEM): A bacterial infection of the uterus spread sexually. It causes abortion and uterine inflammation. Stallions should be cleaned with disinfectant prior to breeding.
Equine Protozoal Myeloencephalitis (EPM): A neurological condition caused by the parasite Sarcocystis neurona, spread by raccoons, skunks, cats, and opossums.
West Nile Virus: A mosquito-borne virus that affects birds and can be zoonotic. It can cause neurological symptoms and fever in horses, but there is an effective vaccine.
Deworming Issues: Antihelminthic resistance is increasing due to misuse of dewormers. Fecal egg counts and proper hygiene are essential for effective deworming.
Horse Ownership Challenges: Horses are often viewed as athletes or livestock, not companions. This can lead to delayed care for illness or injury due to limited financial resources and misinformation.
Dental Care: Horses require regular dental "floating" to remove sharp edges and uneven wear, ensuring proper eating.
Hoof Care: Hoof trimming and balancing are essential for maintaining healthy hooves and preventing lameness.
Laminitis: A painful inflammation of the hoof lamina with several possible causes, such as metabolic diseases, obesity, high starch diets, and injuries . It is a major contributor to death in horses due to the severity of the condition.
