Overview

Randomized trial identifies core gut microbiotas in sows and their links to reproductive performance across Europe, suggesting areas for improvement.

Key Points

  • This research aims to identify core gut microbiota in sows during late gestation and lactation and its relation to performance.
  • Examined gut microbiota composition across six European countries during late gestation and lactation.
  • Conducted differential abundance analyses to assess the relationship between microbial composition and sow performance.
  • Analyzed data from 40 abundant species, focusing on differences between gestation and lactation.
  • Identified two distinct core microbiotas in sows during gestation (~50% abundance) and lactation, with only 21 species overlapping.
  • Low-performing sows maintained higher levels of Streptococcus suis into lactation, indicating a failure to transition microbiota effectively.
  • Differential abundance analysis linked six species, including E. coli and S. suis, to reduced sow performance.
