Evaluations of caecal content characteristics in rabbits fed diets differing in particle size

It is proved that antiperistaltic movements take place in the proximal colon during the hard feces production, and they are induced by small size particles (∅ < 0.315mm) (Bouyssou et al., 1988). These fine particles are carried back to the caecum, causing a longer digesta retention time (Gidenne, 1993) and a higher repletion level...
