摘要： The liver-gut axis is an important regulatory axis for the host's metabolic functions. The study of liver gene expression, changes in metabolic products and the regulation of gut microbial communities in plateau animals under harsh environments can reveal the mechanisms by which Tibetan goats adapt to the plateau environment. This study employs transcriptome, metabolome and metagenomic analyses to reveal the differences in genes, metabolism, and gut microbiota between Jianzhou big-eared goats (JBG) and Xizang cashmere goats (TCG), which is of significant importance for improving survival models of high-altitude ruminants. The results showed that there were 553 DEGs in the liver of JBG and TCG. Hepatic metabolomic analysis revealed significant differences in metabolic activity between the JBG and TCG groups, with notable increases in glycerophospholipid and retinol metabolic pathways. The gut microbiota, including Andreesenia, Dielma, Oscillibacter, Agrobacterium, Hyella and Thermosinus, interact with liver metabolites and can regulate the high-altitude adaptability of goats. This study reveals that TCG enhance immune regulation and energy utilization efficiency by regulating liver gene expression, modulating metabolic pathways, and improving gut microbiota, thereby helping TCG maintain healthy survival capabilities in hypoxic and high-radiation environments.
