This study examined the effects of dietary supplementation with citronella oil and cinnamon oil on the abundance and diversity of the intestinal microbiome in Lingshan native hens and explored how these changes may enhance chicken quality by influencing metabolic pathways. After three months of supplementation, the relative abundance of Firmicutes decreased, whereas Bacteroidota and Proteobacteria increased significantly in the experimental group. Correspondingly, the fatty acid content decreased, whereas the levels of free amino acids and inosine monophosphate (IMP) increased. Correlation analysis revealed a significant positive correlation between IMP content and Proteobacteria, whereas the abundances of Erysipelatoclostridium, Barnesiella, and Faecalitalea were significantly negatively correlated with IMP variation. The abundance of Rikenellaceae_RC9_intestine_group differed across all experimental groups and was strongly correlated with IMP content, suggesting that it is a key microbial factor influencing community composition and chicken traits.
本研究考察了日粮中添加香茅油和肉桂油对灵山土鸡肠道微生物群丰度和多样性的影响，并探讨了这些变化如何通过影响代谢途径来提高鸡肉品质。经过三个月的添加处理后，实验组中厚壁菌门的相对丰度降低，而拟杆菌门和变形菌门显著增加。相应地，脂肪酸含量降低，而游离氨基酸和肌苷单磷酸（IMP）水平升高。相关性分析显示，IMP含量与变形菌门之间存在显著正相关，而丹毒丝菌属、巴恩斯氏菌属和粪栖杆菌属的丰度与IMP变化显著负相关。所有实验组中，理研菌科_RC9肠道菌群的丰度均不同，且与IMP含量密切相关，表明它是影响群落组成和鸡肉性状的关键微生物因素。
