Excess abdominal fat is a common phenomenon in broiler chickens. Gut microbiota could regulate lipid metabolism through their effects on short-chain fatty acids (SCFAs) production. This study was conducted to investigate the potential relationship between development and cecal microorganism populations. Abdominal cecum contents were collected at 3, 7, 14, 21, 28, 35, 42 d of age. The results showed that weight increased with percentage higher 7 21 age than 3 (P < 0.05), it again 28 0.05). Morphological analysis adipocyte diameter cross-sectional area (CSA) significantly after 14 Moreover, gut indicated Chao1 Shannon indices Furthermore, LEfse revealed Faecalibacterium, Anaerotruncus, Anaeroplasma, Subdoligranulum, Clostridium emerged become dominant d.

Isobutyric identified as being negatively associated reverse for conclusion, correlated emergence specific microbes may pivotal establishing this relationship.
