Pasture nonstructural carbohydrates and equine laminitis.

Abstract: Fresh forages constitute a majority of the diet for many horses and ponies that graze on pastures during the growing season in many parts of the world. Grasses generally predominate in such pastures, with varying proportions of legumes. Nonstructural carbohydrates (NSC) (simple sugars, starch, and fructan) can induce laminitis experimentally, and NSC can accumulate to >400 g/kg of dry matter (DM) in pasture grasses. In this article we discuss the environmental factors affecting NSC accumulation in pastures and estimate the potential daily intakes of pasture NSC by grazing horses. We also discuss strategies for both reducing the NSC content of pastures and management practices that can help reduce intakes of pasture NSC by equines at risk of developing laminitis. This study reveals the importance of accurate forage analysis in the development of feeding regimens for equines at risk of laminitis.

The research article focuses on the relationship between the nonstructural carbohydrates (NSC) found in pasture grasses and the development of laminitis in horses. The study offers an in-depth understanding of the environmental influences on NSC accumulation and proposes strategies to minimize NSC content and its intake in horses susceptible to laminitis.

Role of Nonstructural Carbohydrates in Equine Diet

  • The paper highlights the significance of fresh forages including grasses and legumes that form a substantial portion of the diet for grazing horses.
  • Pastures often have high levels of nonstructural carbohydrates (NSCs), consisting of simple sugars, starch, and fructans.
  • Excessive intake of NSCs is linked to the onset of laminitis in equines, a painful and potentially debilitating foot condition.

Environmental Factors Affecting NSC Accumulation

  • The study explores how environmental conditions contribute to the accumulation of NSCs in pasture plants.
  • These factors could potentially cause the levels of NSC to exceed 400 g/kg of dry matter in pasture grasses, posing a risk for horses that consume these grasses regularly.

Potential Daily NSC Intake and Risk of Laminitis

  • The research estimates the potential daily intake of NSCs by grazing horses, drawing a clear link between the intake of these compounds and heightened risk of developing laminitis.

Strategies for Reducing NSC Content and Intake

  • Strategies for minimizing the NSC content in pastures and managing its intake in horses are discussed as preventative measures for laminitis.
  • The importance of accurate forage analysis in crafting feeding schedules for horses at risk of laminitis is underscored as an important part of these preventative strategies.
