In this study, we analyzed the effect of rearing system of ducks on the quantitative and qualitative composition of their gut microfl ora. 180 ducks and 180 drakes of Pekin 44 and Muscovy MR71 lines were kept in the intensive system on litter; the same number of birds was kept in the semi-intensive system. In the latter, starting from the 3rd week of life the birds were allowed to use free ranges. After slaughter of 15 ducks and 15 drakes from each group, their intestinal digesta was subjected to microbiological analysis. The possibility of using the free ranges had a positive effect on the quantitative and qualitative composition of intestinal microfl ora of these birds. The count of aerobic mesophilic heterotrophs in the intestinal digesta of ducks was higher in the case of birds kept in the semi-intensive system. More benefi cial results were achieved in the case of Muscovy ducks considering mainly the coli/lacto ratio which was the lowest (0.08) in this group for both sexes kept on free range. Noteworthy is also that no pathogenic bacteria of the genera: Salmonella, Proteus, Pseudomonas, Staphylococcus, Clostridium perfringens and Escherichia coli were found in any of the analyzed samples.
