Rumen epithelial bacteria intervented by alfalfa supplementation or not

Understanding the rumen epithelial (RE) microbial community structure and population dynamics of young ruminant during development is fundamental in promoting the establishment of a well developed rumen for animal production. In this study, the RE bacteria of 10-day-old Hu lambs fed either milk replacer (B-10), milk replacer and starter (STA) or milk replacer and starter supplemented with alfalfa (S-ALF) in the pre- (d17, 24, and 38) and post-weaning periods (d45 and 66) were assessed to characterize RE bacterial colonization during early life and its response to fiber intervention. The findings of this study provide clues for strategies to improve rumen health through manipulation of the RE bacteria during early life.
