2022年12月1日 · The yak rumen microbiome likely increased its ability to degrade forage not only by enhancing cellulose degradation (as evidenced by enriched GHs involved in cellulose hydrolysis) but also by enhancing hemicellulose and pectin degradation.

2016年6月1日 · Methanobrevibacter is the predominant archaea of rumen microbiota in grazing yaks. Highly diverse microflora of uncultured or unclassified microorganisms. Prevotella was the predominant genus, account for 28.5% of all rumen genera. Yak is an important domesticated ruminant on the Qinghai-Tibet Plateau in China.

2019年5月22日 · In the current study, we characterized the effect of feed type on the ruminal fluid microbiota and metabolites in yak using 16S rRNA gene sequencing and liquid chromatography-mass spectrometry (LC-MS). Bacteroidetes and Firmicutes were the predominant bacterial phyla in the yak rumen.

2022年9月22日 · Yak rumen contain a complex network of symbiotic microorganisms that can synergistically ferment plant fibers, providing nutrients for themselves and the host (Ishaq and Wright, 2012). In this study, we identified interactions …

2018年8月22日 · The ruminant digestive system harbors a complex gut microbiome, which is poorly understood in the case of the four stomach compartments of yak. High-throughput sequencing and quantitative PCR were used to analyse microbial communities in the rumen, reticulum, omasum, and abomasum of six domesticated yak.

The complex microbial community that resides within the yak rumen is responsible for fermentation and contributes to its climatic adaptation. This study aimed to characterize the rumen microbiota responses to wide seasonal variations, especially those necessary for …

2023年7月21日 · The findings of the current study provide proper energy requirements for yaks would facilitate scientific feeding of fattening yaks in cold weather. The metabolomics and 16s rRNA sequencing technologies were used to explore the underlying mechanism that affects the growth performance of yaks fed with different energy levels of diet in cold weather.

2018年11月29日 · The rumen microbiota of ruminants plays a vital role in fiber digestion, and environmental factors affect its community structure. The yak (Bos grunniens) is the main livestock species that inhabits the Qinghai-Tibet Plateau (QTP) at regions located at high-altitude of 3,000–5,000 m.

2023年9月22日 · Our study aims to lay a molecular basis for the study of the physiological functions of rumen, reticulum, omasum and abomasum in yaks. It can further elucidate the important roles of these mRNAs in regulation of growth, development and metabolism in yaks, and to provide a theoretical basis for age-appropriate weaning and supplementary feeding ...
