Laminitis is a painful and debilitating condition of horses and ponies that has major economic and welfare implications. Anecdotal observations and the results of survey studies have indicated that most laminitis cases occur in horses and ponies kept at pasture (hence, the term pasture-associated laminitis). Risk for development of pasture-associated laminitis represents a dynamic interaction between animal predisposing factors (an insulin-resistant phenotype commonly termed equine metabolic syndrome) and environmental conditions, particularly the nonstructural carbohydrate (simple sugars, starches, and fructans) content of pasture forage. Countermeasures for avoidance of pasture-associated laminitis involve (1) mitigation of metabolic predisposition (insulin resistance and obesity) in high-risk horses and ponies and (2) dietary and pasture grazing management strategies that minimize exposure to the dietary conditions known to trigger laminitis in susceptible animals.
蹄叶炎是马和矮种马的一种痛苦且使人衰弱的病症，具有重大的经济和福利影响。轶事观察和调查研究结果表明，大多数蹄叶炎病例发生在放牧的马和矮种马身上（因此，有“与牧场相关的蹄叶炎”这一术语）。与牧场相关的蹄叶炎发病风险代表了动物易感因素（通常称为马代谢综合征的胰岛素抵抗表型）与环境条件之间的动态相互作用，特别是牧场草料中的非结构性碳水化合物（单糖、淀粉和果聚糖）含量。避免与牧场相关的蹄叶炎的对策包括：（1）减轻高危马和矮种马的代谢易感性（胰岛素抵抗和肥胖）；（2）采取饮食和牧场放牧管理策略，尽量减少易感动物接触已知会引发蹄叶炎的饮食条件。
