Implication

Randomized controlled trial shows decreased pathogenic bacteria in fecal microbiota of calves, suggesting multi-species probiotics may control gastrointestinal pathogens.

Key Points

  • Probiotic administration decreased Clostridium perfringens in the feces of pre-weaned dairy calves on Day 7.
  • At 7 days, diarrheic calves in the control group had a higher abundance of Fusobacterium varium compared to non-diarrheic calves.
  • Analysis utilized 16S rRNA amplicon sequencing to evaluate fecal bacterial populations across four age timepoints.
  • Findings suggest potential for multi-species probiotics to manage pathogenic bacteria in dairy calves' gastrointestinal health.
