How can grazing reduce the risk of laminitis in horses?

Laminitis, defined as the inflammation and damage to the laminae in the hoof of animals, particularly horses and cows, can be debilitating and even fatal. While grazing management alone cannot eliminate the risk, strategic grazing practices can play a significant role in reducing the risk of laminitis in horses.

How Can Grazing Reduce the Risk of Laminitis in Horses?

Careful grazing management helps control the amount of sugar and starch a horse consumes, which is a key factor in preventing laminitis. By understanding the factors that influence sugar levels in grass and implementing appropriate strategies, horse owners can create a safer grazing environment.

What Factors Influence Sugar Levels in Grass?

Several factors impact the sugar content in grass, including:

• Time of Day: Sugar levels are typically lowest in the early morning and increase throughout the day as the plant photosynthesizes.
• Weather Conditions: Sunny days promote photosynthesis and increase sugar production. Cool nights can prevent the plant from using these sugars, leading to higher concentrations.
• Grass Species: Some grass species naturally contain higher levels of sugar than others.
• Stress: Stressed grasses, due to overgrazing or drought, tend to accumulate more sugars.

What Grazing Strategies Can Help?

Implementing these grazing strategies can help reduce the risk of laminitis:

1. Early Morning Grazing: Allow horses to graze during the early morning hours when sugar levels in the grass are at their lowest.
2. Avoid Grazing After Sunny Days and Cool Nights: Limit or avoid grazing on these days, as the grass will likely have elevated sugar levels.
3. Choose Low-Sugar Grass Species: Opt for pasture mixes that include grass varieties known for lower sugar content.
4. Rotational Grazing: Implement a rotational grazing system to prevent overgrazing and allow grasses to recover, reducing stress and sugar accumulation.
5. Limit Grazing Time: Restrict the amount of time horses spend grazing, especially during high-risk periods.
6. Use a Grazing Muzzle: A grazing muzzle can help reduce grass intake, particularly for horses prone to laminitis.

What Else Can I Do to Prevent Laminitis?

Besides grazing management, other important factors in preventing laminitis include:

• Maintain a Healthy Weight: Obesity is a significant risk factor for laminitis.
• Provide a Balanced Diet: Ensure your horse receives a balanced diet with appropriate levels of nutrients.
• Regular Exercise: Regular exercise helps maintain a healthy metabolism and reduces the risk of obesity.
• Regular Farrier Care: Proper hoof care is essential for maintaining hoof health and preventing laminitis.

What Are the Signs of Laminitis?

Early detection is crucial for managing laminitis. Common signs include:

• Lameness: Difficulty walking, especially on hard surfaces.
• Heat in the Hooves: Increased temperature in the hooves.
• Increased Digital Pulse: A stronger pulse in the digital arteries of the lower leg.
• Reluctance to Turn: Difficulty or reluctance to turn.
• "Laminitic Stance": A characteristic stance with the front feet stretched out and the hind feet camped under the body.

When Should I Call a Vet?

If you suspect your horse has laminitis, contact your veterinarian immediately. Prompt diagnosis and treatment are essential to minimize damage and improve the horse’s chances of recovery.

Strategic grazing management is a valuable tool in reducing the risk of laminitis in horses. By understanding the factors that influence sugar levels in grass and implementing appropriate grazing strategies, horse owners can create a safer and healthier environment for their equine companions.
