Overview

A study shows compound probiotics enhance growth and immune function in broiler chickens, suggesting better health outcomes.

Key Points

  • The aim is to evaluate how a multi-strain probiotic affects growth and health in broiler chickens.
  • 144 Ross 308 broilers were assigned to two diet groups for 42 days.
  • One group received a basal diet, while the other received a diet supplemented with 0.3% compound probiotics.
  • Growth performance, meat quality, and immune responses were measured and analyzed.
  • Intestinal health was assessed by examining morphology and gene expression related to gut barriers.
  • Probiotic supplementation significantly improved average daily gain and reduced feed conversion ratio.
  • Meat quality improved, indicated by higher pH45min and reduced shear force and drip loss.
  • Serum levels showed increased immunoglobulin G and interleukin-10, with reduced pro-inflammatory cytokines.
  • Intestinal morphology was enhanced, with increased expression of barrier-related genes like mucin-1 and claudin-1.
  • Cecal microbiota analysis revealed a higher abundance of beneficial bacteria.
