Characterisaon of differences in gut microbiota <strong>and</strong> gut <br />
funcon of chickens with good <strong>and</strong> poor <strong>feed</strong> <strong>efficiency</strong> <br />
Experimental design: <br />
2 partner instuons (AFBI & Vetmeduni) performed idencal chicken experiments <br />
with 3 batches of 50/64 chicks <br />
Similar chicken genec: Cobb 500FF <br />
Similar maize-‐soybean meal diets (starter, grower, <strong>and</strong> finisher diets) <br />
No in-‐<strong>feed</strong> anbiocs <strong>and</strong> any other gut health-‐related addives <br />
Chickens were individually housed <br />
Best <strong>and</strong> worst <strong>feed</strong> efficient chickens were idenfied using Residual Feed Intake <br />

On day 42, samples were collected for: <br />
Ileal <strong>and</strong> caecal digesta for metagenomics <strong>and</strong> microbial metabolites <br />
Tissue of duodenum, jejunum, ileum, caeca for gut funcon <strong>and</strong> structure <br />
