Managing Spring Pasture Turnout for Horses: Tips and Considerations

As the weather warms and spring is now here, horse owners eagerly anticipate turning their horses out to pasture after a long winter. However, this transition period requires careful management to ensure the health and well-being of your horses. Abruptly introducing horses to lush spring pasture can lead to various health issues such as laminitis and colic, due to the sudden change in diet and intake of rich grasses.

Understanding the Risks:

Spring pastures, bursting with new growth, are typically high in sugars and fructans, which can be problematic for horses if consumed excessively. Here are some key risks associated with spring pasture turnout:

1. Laminitis: A painful and often debilitating condition affecting the hooves, laminitis can be triggered by sudden access to high-sugar grasses.

2. Colic: Rapid changes in diet, such as the switch from hay to fresh pasture, can upset the delicate balance of a horse's digestive system, potentially leading to colic.

3. Obesity and Metabolic Issues: Some horses may gain weight quickly on lush pasture, exacerbating conditions like insulin resistance and equine metabolic syndrome.

Gradual Turnout Strategy:

To mitigate these risks, a gradual introduction to spring pasture is crucial. Here’s a structured approach:

1. Monitor Grass Growth: Assess the pasture regularly to determine when it's safe to start turnout. Ideally, wait until the grass is at least 6-8 inches tall and has fully matured. The taller the grass the higher fiber content it has. The majority of the sugar is stored at the base of the grass, hence why short grass is much higher in sugars and fructans.

2. Limit Grazing Time: Begin by turning out horses for short periods, gradually increasing their grazing time over several days to allow their digestive systems to adjust.

3. Use a Grazing Muzzle: For horses prone to weight gain, metabolic issues, or laminitis consider using a grazing muzzle during turnout to restrict grass intake while still allowing them to enjoy being outside.

4. Provide Alternative Forage: Continue offering hay or other forage to supplement the pasture intake, helping to maintain a more consistent diet.

5. Monitor Health: Watch closely for any signs of discomfort or changes in behavior that could indicate health issues such as lameness or colic.

Managing Pasture Health:

Beyond the initial turnout period, effective pasture management is essential for maintaining both the health of the horses and the quality of the grazing area:

1. Rotational Grazing: Divide pastures into smaller paddocks and rotate grazing areas to prevent overgrazing and allow grass to recover.

2. Regular Maintenance: Control weeds, aerate soil, and manage water drainage to promote healthy grass growth.

3. Fertilization and Soil Testing: Test soil regularly to ensure proper nutrient levels, and fertilize as needed to maintain pasture health.

4. Rest Periods: Allow pastures to rest periodically to prevent depletion of grass resources and promote regrowth.

5. Water Access: Ensure horses have access to clean, fresh water at all times, especially when grazing.

Spring pasture turnout is a joyous time for horses and owners alike, but it requires careful planning and management to avoid potential health risks. By gradually introducing horses to pasture, monitoring their health closely, and practicing good pasture management techniques, you can help ensure a safe and enjoyable grazing experience for your equine companions throughout the spring and beyond.

Remember, each horse is unique, so tailor your management approach to suit their individual needs and health considerations. With proper care and attention, spring pasture turnout can contribute positively to the overall well-being of your horses, allowing them to thrive in a natural environment while minimizing the risks associated with rapid dietary changes.

Happy grazing!
