Gut health is of major importance in animals. The gastrointestinal mucosa is the first tissue that comes in contact with dietary constituents. Anything that affects the health of the gut will influence the animal as a whole, and consequently alter its nutrient uptake and requirements. LICUICEL or PROCELFEED range products help in a sustainable poultry production to secure intestinal health, minimizing the enviromental impact, improving animal welfare and letting the birds perform to their maximum Improvements in growth performance observed in broilers fed butyrate and essential oils may be attributed to a lower inflamatory response to nutritional, enviromental and immune challenges associated with improved digestibility and absortion of dietary nutrients.
