Assessment of Feed Value of Chicory and Lucerne for Poultry, Determination of Bioaccessibility of Their Polyphenols and Their Effects on Caecal Microbiota

Chicory and lucerne possess high feed value for poultry being good sources of protein fiber. In addition, they are rich in polyphenols that help the body build an integrated antioxidant system to prevent damage from free radicals positively modulate microbial populations gastrointestinal tract. These health-promoting effects depend on their bioaccessibility absorption animal body. The present paper aimed study chicory after subjecting samples gastric intestinal phases digestion vitro model chicken gut assessment by measuring presence fermentable substrates (in terms gas production), SCFAs produced microbiota population during cecal fermentation. Results revealed varied with different polyphenol compounds. highest was recorded p-hydroxybenzoic acid (90.8%) following phase digestion. lowest observed quercetin-3-rhamnoside (12.6%) From lucerne, kaempferol-3-glucoside (77.5%) Total production higher (39.9 mL/g) than (28.1 mL/g). Similarly, total 24 h fermentation (42.2 mmol L?1) as compared (38.1 L?1). also relative abundance Clostridium reduced (0.225%) (0.176%) control (0.550%) Streptococcus (4.845%) but increased (17.267%) (5.204%) findings indicated differentially affected
