Table 2 Kruskal–Wallis p-values for interactive Time × TRT (fed or delayed access to feed) or main (time and TRT) effects for alpha diversity indices in ileal (IL) and cecal (CE) luminal (L) and mucosal (M) samples collected from days 1 (24 h) to 14 (336 h) post-hatch

From: Delayed access to feed early post-hatch affects the development and maturation of gastrointestinal tract microbiota in broiler chickens
