with lower abundance ofBacteroidetesandActinobacteria. In broiler chickens, several studies showed thatLactobacilliare the major bacterial population in three segments (duodenum, jejunum, and ileum) of the small intestine, whereasClostridiumandBacteroidesare dominant in the ceca24,53. In emu, ...
Most studies of avian species have focused on characterizing the microbiota in the ceca due to its large bacterial diversity13,14,15,16. Examination of omnivorous avian species shows thatBacteroidetesis the dominate phylum in the ceca15,17,18,19,20,21. In contrast,Firmicutesdominate in the ceca...
