Use of Chicory (Cichorium intybus) and its Derivatives in Poultry Nutrition

Chicory (Cichorium intybus) is a perennial herb that belongs to the Asteraceae family. Certain species are grown and used as fried, dry salad leaves, roots, or chicons as a substitute for coffee additives. It is also cultivated as forage that can be used in animal feeding. In addition, chicory has significant effects on animal and human health and has various biological activities, such as immunostimulant, antimicrobial, antioxidant, hyperlipidemic, anti-inflammatory, and antidiabetic activity. Chicory extracts protect the liver by lowering the levels of liver enzymes, e.g., aspartate aminotransferase (AST), alanine aminotransferase (ALT), and alkaline phosphatase (ALP). The chicory plant plays a key role in protecting hepatocytes and other liver cells. It is used as an antimicrobial agent in vitro and in vivo against certain pathogenic bacteria species. Chicory improves immunity and feed efficacy by reducing pathogenic microorganisms in the gastrointestinal tract. Cichorium intybus roots were also used to alleviate slight intestinal disturbances, including the sense of flatulence, full abdomen, transient appetite loss, and indigestion. This chapter describes the role of chicory plants in promoting growth when used as feed additives in poultry feed. It also explains the mechanisms of action of chicory extracts and their role as a liver protector for poultry.
