Feed particle size effects on morphology and glycoconjugate pattern was investigated in the rabbit intestine. Rabbits fed with fine particles (2 mm) displayed more irregularly shaped, higher duodenal villi and deeper crypts in distal colon as well as higher number of goblet cells than coarse (8 mm) fed ones. Brush border expressed: (i) in duodenum, neutral/sulfated glycoconjugates and glycans binding MAL II, SNA, Con A than KOH-sialidase-PNA and DBA reactivity in fine and coarse fed rabbits, respectively, (ii) in cecum, mainly sulfoglycans in coarse fed rabbits, MAL II and PNA staining in all samples, and (iii) in distal colon few sulfoglycans and MAL II reactivity. Enterocytes bound MAL II in duodenum, Con A in cecum, DBA, and Con A in distal colon of all rabbits, SNA in distal colon of coarse fed ones. Brunner's glands displayed high presence of acidic/sulfated mucins in fine fed rabbits, neutral glycoconjugates and reactivity with MAL II, SNA, PNA, KOH-sialidase-PNA, and Con A in all rabbits. Goblet cells exhibited: (i) in duodenum neutral and sulfomucins as well as MAL II and KOH-sialidase-PNA staining, than SNA and DBA in fine and coarse fed rabbits, respectively, (ii) in cecum sulfated glycans, MAL II, SNA, KOH-sialidase-PNA, DBA reactivity, and (iii) in distal colon acidic/sulfomucins, MAL II and SNA staining, and DBA reactivity in fine fed specimens. Crypt cells exhibited neutral and PNA reactive glycoconjugates in the cecum. In the distal colon also acidic/sulfated glycans, and MAL II, KOH-sialidase-PNA, DBA; SNA staining showed weaker reactivity in fine fed rabbits, which bound Con A.
