Abstract: Pigs in four groups were fed fine non-pelleted (F-NP), fine pelleted (F-P), coarse non-pelleted (C-NP) or coarse pelleted (C-P) diets. DNA fingerprints, T-RFLP, revealed a strong dietary effect on bacterial community structure in the stomachs. Pigs fed the C-NP diet had the highest microbial diversity in stomach and the T-RFLP fingerprints suggested that bacteria tentatively identified as 'Lactobacillus delbrueckii', 'L. mucosae', 'L. reuteri', 'L. amylovorus'/'L. sobrius', 'Mitsuokella multiacida' and 'Megasphera elsdenii' were specifically stimulated. Lactobacilli may be responsible for the previously reported increase in stomach lactate levels of pigs fed the C-NP diet [Mikkelsen, L.L., Naughton, P.J., Hedemann, M.S., Jensen, B.B., 2004. Effects of physical properties of feed on microbial ecology and survival of 'Salmonella enterica' serovar Typhimurium in the pig gastrointestinal tract. Appl. Environ. Microbiol. 70, 3485–3492.]. Moreover, earlier observations of butyrate and propionate accumulation in the stomach of pigs fed C-NP diets could be due to stimulation of 'M. elsdenii' and 'S. ruminantium' according to the T-RFLP fingerprints.
