Heat stress in poultry farming
Heat stress is now a major challenge for the poultry industry. When it occurs, it triggers a series of disorders that can affect:
- Hydration
- Electrolyte balance
- Feed intake
- The animals’ overall comfort
Although these effects may sometimes be imperceptible at first, they can quickly impact product quality and zootechnical performance.peuvent rapidement impacter la qualité des produits et les performances zootechniques.
Impact on laying hens and breeders
In laying hens, heat can reduce feed intake and compromise egg quality. Shell formation becomes more sensitive to fluctuations in electrolyte balance.
In breeders, these episodes also affect the quality of hatching eggs and the fertility of roosters, which can impact the performance of future chicks.
Consequences for broilers
Broilers are also highly sensitive. Reduced feed intake and heat-related metabolic adjustments can lead to slowed growth, increased heterogeneity within the flock and greater variability in performance. Under these conditions, maintaining water balance becomes crucial for supporting the animals’ robustness.
