Abstract: This experiment was conducted to establish a technical platform for metabolite analysis based on chromatography-mass spectrometry (UPLC-Q-TOF-MS/MS), three-week-old chickens were feed with equal dose of the Chinese veterinary drug andrographolide (AG) and the broad-spectrum antibiotic oxytetracycline (OTC) respectively, to analyze the metabolite changes in the excretion of chickens after intervention. Through statistical analysis of the data, differential metabolites were obtained, and the intervention mechanism of AG and OTC on chicken gut microbiota metabolism were also explored. The excretory samples of yellow-finned chickens in each group were detected by UPLC-Q-TOF-MS/MS, and the metabolic pathways were enriched and analyzed by MetaboAnalyst platform. The differential metabolites were screened by using QI software. The results showed that compared with the blank group, 12 and 10 differential compounds were found in OTC and AG group, respectively. Fifteen metabolic pathways were involved in the OTC group, of which 2 most relevant metabolic pathways were linoleic acid and glycerophospholipid metabolism; 17 metabolic pathways were involved in the AG group, of which 5 most relevant metabolic pathways were glycerophospholipid metabolism, sphingolipid metabolism, cysteine and methionine metabolism, unsaturated fatty acid biosynthesis and glycine, serine and threonine metabolic pathways. It can be concluded that the mechanism of action of OTC and AG affecting chicken metabolism is very similar, both can affect the normal metabolic function of chickens through changing phospholipid metabolism, fatty acid metabolism and amino acid metabolism, especially the distribution pattern of OTC group is significantly different from the control group.
