Age-dependent variations in rumen bacterial community of Mongolian cattle from weaning to adulthood por Ahmad, A.A., Zhang, J., Liang, Z., Du, M., Yang, Y., Zheng, J., Yan, P., Long, R., Tong, B., Han Jianlin, Ding, X.

“…Previous studies showed that the rumen microbiome of Mongolian cattle has adapted to degrade the rough forage to provide sufficient energy to tolerate the harsh desert ecological conditions. However, little is known about the succession of rumen microbes in different developmental stages of post-weaning Mongolian cattle.Here, we examined the succession of the rumen microbial composition and structure of 15 post-weaning Mongolian cattle at three developmental stages i.e., 5 months (RM05), 18 months (RM18) and, 36 months (RM36) by using the 16S rRNA gene sequencing method.We did not find any age-dependent variations in the ruminal concentrations of any volatile fatty acid (VFA) of Mongolian cattle. …”
