Transcriptome profiling in rumen, reticulum, omasum, and abomsum tissues of yak during the developmental transition of pre-ruminant to the ruminant

This study provides a clear and accurate dynamic transcriptome profile of mRNAs in rumen, reticulum, omasum and abomasum of yaks. The results include high-quality genomic data and help to elucidate the important roles of these mRNAs in regulation of growth, development and metabolism in yaks, and to further understand the molecular mechanisms underlying metabolic regulation of yak stomach tissues. At the same time, it provided a theoretical basis for age-appropriate weaning and supplementary feeding in yaks. Overall design: we first compared mRNA expression levels of rumen, reticulum, omasum, and abomasum of yaks in five developmental stages (0 d, 20 d, 60 d, 15 m and adult after birth).
