Dynamics of rumen gene expression, microbiome colonization, and their interplay in goats

Abstract

The present study touched the critical developmental process of rumen functions, microbial colonization and their functional interactions during preweaned development. Taken together, these results demonstrated that rumen development at the first phase is more likely a programmed process rather than stimulation from feed and the microbiome, while the shift of rumen metagenomes was likely regulated by both the diet and host. The intensive functional correlations between rumen genes and the microbiome demonstrated that synergistic processes occurred between them during early rumen development.
