Evaluating amino acid requirements, specifically threonine requirements, in horses will enable better feed formulation and result in economic production, improved animal health, and reduced environmental pollution. However, the current knowledge of protein and amino acid requirements in horses is still limited. Because horses have a unique digestive system and consume a variety of feed ingredients, their protein digestibility may be affected than other species by different feed composition, and thus amino acid requirements are susceptible to vary between situations. Therefore, a careful evaluation of amino acid requirements with a proper method is needed for various conditions. This review will also provide comprehensive information that needs to be considered when designing an amino acid requirement study in horses.
评估马匹的氨基酸需求，特别是苏氨酸需求，将有助于更好地配制饲料，并实现经济生产、改善动物健康和减少环境污染。然而，目前关于马匹蛋白质和氨基酸需求的知识仍然有限。由于马具有独特的消化系统，且食用多种饲料成分，其蛋白质消化率可能比其他物种更容易受到不同饲料组成的影响，因此氨基酸需求在不同情况下可能会有所不同。因此，需要采用适当的方法针对各种条件仔细评估氨基酸需求。本综述还将提供在设计马匹氨基酸需求研究时需要考虑的全面信息。
