Do milk purine derivatives reflect the urinary PDC index in dairy cows? Insights from integrative milk–urine metabolomic profiling

The supplementary material is an excel file containing the following sheets: a) urine metabolites annotated through untargeted UHPLC-HRMS approach; b) milk metabolites annotated through untargeted UHPLC-HRMS approach; c) relationship between urinary allantoin and uric acid concentrations (mmol/L) independent from treatment.

本补充材料为一份Excel文件，包含以下工作表：
a) 经非靶向超高效液相色谱-高分辨质谱（untargeted UHPLC-HRMS）方法注释得到的尿液代谢物；
b) 经非靶向超高效液相色谱-高分辨质谱方法注释得到的乳汁代谢物；
c) 不受实验处理影响的尿液尿囊素与尿酸浓度（单位：mmol/L）之间的关联关系。
