Rumen microbiota are closely linked to feed utilization and environmental adaptability of ruminants. At present, little is known about the influence different extreme environments on rumen yaks. In this study, 30 ruminal fluid samples from healthy female yaks (average 280 kg BW) in 5-8 years life were collected three regions Tibet, China, compared by gas chromatography high-throughput sequencing. Results showed that propionic acid, butyric total volatile fatty acids significantly (
