- •
Intestinal inflammation associated with stress triggers negative feedback on serum corticosterone concentrations.
- •
Intestinal inflammation induces the increased serum corticosterone level.
- •
A stereological approach to splenic germinal centres proved to be a sensible and useful tool in assessing the immune status of broilers.
- •
Heat stress reduces splenic germinal centre formation.
