Linear discriminate analysis effect size (LEfSe) showing significant taxa (biomarkers, in bold) in the faeces of the ponies for each sampling day (D) when ponies (n = 6) were maintained on grass (G).

Linear discriminate analysis effect size (LEfSe) showing significant taxa (biomarkers, in bold) in the faeces of the ponies for each sampling day (D) when ponies (n = 6) were maintained on grass (G).线性判别分析效应量（Linear Discriminant Analysis Effect Size，LEfSe）分析结果显示，在6匹饲喂青草日粮（G）的矮马粪便中，各采样日（D）下均存在以粗体标注的显著差异分类群（生物标记物，biomarkers）。
