Overview

Analysis shows heat stress reduces IGF-1 levels and growth in broilers, suggesting impacts on poultry management.

Key Points

  • Heat stress negatively affects serum concentration of IGF-1 in chickens, impacting their growth performance.
  • Significant downregulation of IGF-1 was observed in chickens under heat stress conditions at two developmental stages.
  • Analysis of growth performance and gene expression was conducted in fast-growing and slow-growing chicken genotypes.
  • These findings highlight the importance of managing heat stress to optimize growth in poultry and mitigate losses.
