What are the risks of laminitis in horses during winter?

Laminitis is an inflammation and damage to the laminae in the hoof of animals like horses, often triggered by factors such as a poor diet or obesity. This condition can lead to extreme pain and may even be fatal if not properly managed.

What is Laminitis?

Laminitis, commonly known as founder, involves inflammation and damage to the laminae within a horse’s hoof. The laminae are the interlocking tissues that connect the hoof wall to the coffin bone. When these structures become inflamed, the connection weakens, potentially leading to rotation or sinking of the coffin bone within the hoof.

What Causes Laminitis in Horses During Winter?

While laminitis is often associated with lush spring pastures, it can occur in winter due to several factors:

• Dietary Changes: Changes in feeding routines, such as increased grain to maintain body weight in cold weather, can disrupt the hindgut microbiome and trigger laminitis.
• Metabolic Issues: Horses with underlying metabolic conditions like Equine Metabolic Syndrome (EMS) or Pituitary Pars Intermedia Dysfunction (PPID, Cushing’s) are more susceptible, as their bodies struggle to regulate insulin levels, especially with dietary changes.
• Reduced Exercise: Limited turnout due to weather can lead to weight gain and decreased insulin sensitivity, exacerbating the risk.
• Stress: Cold stress and changes in social dynamics within the herd can also contribute to the development of laminitis.

How Can You Prevent Winter Laminitis?

Preventing laminitis in winter involves careful management and attention to the horse’s specific needs:

1. Maintain a Consistent Diet: Avoid sudden changes in feed. If increasing grain, do so gradually.
2. Manage Weight: Monitor body condition and adjust feed accordingly to prevent obesity.
3. Provide Regular Exercise: Encourage movement, even if it means hand-walking or arena work.
4. Address Metabolic Issues: Work with your veterinarian to manage EMS or PPID through medication and diet.
5. Foot Care: Regular trimming and hoof care are essential to maintain proper hoof balance and health.

How do I recognize early signs of laminitis?

Early signs include increased digital pulse, heat in the hooves, reluctance to turn, and a "walking on eggshells" gait. Catching these signs early is crucial for prompt intervention.

Can blankets help prevent laminitis?

While blankets won’t directly prevent laminitis, they can reduce cold stress, which can be a contributing factor. Ensure blankets fit well and are appropriate for the weather conditions.

What type of bedding is best for horses prone to laminitis?

Opt for low-dust and low-sugar bedding options like shredded paper or wood shavings. Avoid bedding that horses might ingest, as this can lead to dietary imbalances.

Understanding the risks and implementing preventive measures can help keep your horse sound and healthy throughout the winter months.
