Brachiaria decumbens is an extremely productive tropical grass due to its aggressive growth habit and its adaptation to a varied range of soil types and environments. As a result of the vast availability, treated B. decumbens demonstrates as a promising local material that could be utilised as an improved diet for sheep and goats. Despite the fact that the grass significantly increases weight gains in grazing farm animals, there were many reports of general ill-thrift and sporadic outbreaks of photosensitivity in livestock due to the toxic compound of steroidal saponin found in B. decumbens. Ensiling and haymaking were found to be effective in removing toxin and undesirable compounds in the grass. Biological treatments using urea, activated charcoal, polyethylene glycol, and effective microorganisms were found to be useful in anti-nutritional factor deactivation and improving the nutritive values of feedstuffs. Besides, oral administration of phenobarbitone showed some degree of protection in sheep that fed on B. decumbens pasture. In this review, we aim to determine the effect of B. decumbens toxicity and possible treatment methods on the grass to be used as an improved diet for small ruminant.
俯仰臂形草是一种高产的热带牧草，因其生长习性旺盛且能适应多种土壤类型和环境。由于其产量丰富，经过处理的俯仰臂形草被证明是一种有前景的本地材料，可用作绵羊和山羊改良饲料。尽管这种草能显著增加放牧家畜的体重，但有许多报告称，由于俯仰臂形草中发现的甾体皂苷有毒化合物，家畜普遍生长不良且偶尔会爆发光敏反应。青贮和制干草被发现对去除草中的毒素和不良化合物有效。使用尿素、活性炭、聚乙二醇和有效微生物进行生物处理，被发现有助于使抗营养因子失活并提高饲料营养价值。此外，口服苯巴比妥对食用俯仰臂形草牧场的绵羊有一定程度的保护作用。在本综述中，我们旨在确定俯仰臂形草毒性的影响以及对该草进行处理使其用作小型反刍动物改良饲料的可能方法。
