Overview

Shows the effects of prebiotic supplementation on lamb microbiome diversity and growth performance, suggesting enhanced nutrition strategies.

Key Points

  • To investigate how mannan-rich fraction (MRF) supplementation influences rumen microbiome development and growth in lambs.
  • Used metagenomic sequencing and gas chromatography to analyze microbiome diversity.
  • Examined lambs receiving MRF through maternal and direct supplementation at different age points.
  • Analyzed alpha and beta diversity metrics and their associations with volatile fatty acids.
  • Lambs with direct MRF supplementation showed significantly greater microbial diversity at week 8.
  • Combined maternal and lamb MRF supplementation resulted in the highest microbiome diversity at week 20.
  • Positive correlations were found between alpha diversity metrics and volatile fatty acids, particularly butyrate and valerate.
