Overview

Evaluates the impact of postbiotic supplementation on calf growth and health, suggesting enhanced performance outcomes.

Key Points

  • The research aims to assess how supplementation with Saccharomyces cerevisiae-derived postbiotics affects calf growth, health, and rumen fermentation.
  • Conducted two independent experiments with 144 calves from 400 pregnant Holstein cows.
  • Calves randomly assigned to receive or not receive postbiotics in their diet.
  • Measured growth performance, health indicators, rumen fermentation, and microbial composition over the first 70 days.
  • Calves receiving postbiotics showed greater weaning weights and preweaning average daily gains.
  • Preweaning diarrhea incidence was significantly reduced in supplemented calves.
  • Rumen microbial diversity remained unchanged, but there were increased levels of volatile fatty acids and ammonia nitrogen in one group.
