Modulation de la composition l'écosystème digestif caecal du lapereau par voie alimentaire et relation avec son fonctionnement

National audience; The objectives were to evaluate the possibility to modulate the implantation of the ceacal microbiota through diet, and to study the relationship between the composition and the function of this ecosystem. The incorporation of rapidly fermentable fibres (FRF) in the pelleted feed of rabbit pups from 15 days of age (D15), or the use of an antibiotic treatment, on the rabbit does or the pups, were used as inhibitors or stimulants of the implantation of the caecal microbiota. An antibiotic treatment of the does did not alter the composition of the caecal microbiota in nursing pups (D15). Conversely, at D29 the microbial composition was different (P
