Abstract: Objective　The study employs microbial diversity composition profiling and metagenomic sequencing to investigate the compositional characteristics and functional analysis of respiratory and intestinal microbiota in sheep from Jilin Province, China, thereby providing foundational data for the establishment of experimental sheep models.Methods　Microbiota diversity composition profiles and metagenomic sequencing were performed on respiratory and intestinal samples from 200 sheep.Results The study revealed the composition of the respiratory and intestinal microbiota of sheep, as well as their respective characteristics in terms of microbiota structure and functional potential.Conclusion　The findings provide insights into the respiratory and intestinal microbiota of sheep and their functions, offering a solid theoretical foundation for establishing detection standards for experimental sheep.
