Gut health’s impact on broiler’s immune status
Genetic selection has enabled the poultry sector to achieve heavier broilers. Birds have been selected for their capacity to grow, but also for a higher feed intake. Meanwhile, 70% of the birds’ immune system capacity is concentrated around or inside the gut, i.e. Gut associated lymphoid tissue (GALT), Peyer patches, spleen, liver, Fabricius bursa. It is thus essential to maintain the bird’s gut health which impacts the bird’s immune status, in the face of the different challenges and violations of the digestion and the absorption of the birds.
The industry has also explored the potential inclusion of yeast-based products in feeding rations to boost birds’ natural defences. Yeast fractions such as Safmannan® are known to positively influence gut microflora, gut morphology and immunity.
