| 摘 要： | 基于流行病学的角度，旨在初步探索与新生羔羊疾病相关的代谢标识物。本研究采用病理对照试验设计，利用高效液相色谱串联质谱比较病危临死新生羔羊与健康新生羔羊（相同日龄）的血清代谢差异。结果显示：两组血清代谢物能得到较好区分，共鉴定出13种差异代谢物，KEGG富集分析显示，这些差异代谢物主要富集在氨基酸生物合成和代谢通路上。羔羊濒死过程中血清内源性代谢物发生明显改变，可为新生羔羊疾病诊断标识物的筛选和构建提供基础。

| Abstract: | This study aimed to explore the metabolic differences in sera of antemortem neonatal goats based on an epidemiological perspective. A case-control design was used to discover the metabolic differences in serum between the dead newborn goats suffered from a disease and healthy goats at the same age by using UPLC-MS/MS. A total of 13 compounds were significantly different between healthy and dead newborn goats. KEGG analysis showed that these differential produced metabolites mainly involved the synthesis and catabolism of amino acids. The differential produced metabolites in serum are important for us to understand the agonal reaction at the metabolic level when neonatal goats suffering from a disease. This study also provides an advanced research basis for the establishment of disease-related biomarkers for neonatal goats which may suffer from a disease. |
