The purpose of this investigation was to study the influence of the prebiotic Salgard and an herb mixture (rosemary, thyme, basil, oregano and cinnamon) on the histostructure of some internal organs and on the intestinal microflora of Pekin ducklings in an organic production system. Seventy two Pekin ducklings distributed randomly into 3 groups of 24 birds each and sexed (12 ♂and 12 ♀) were used as followed: group I (control) fed a standard diet; group II - fed the same diet supplemented with the prebiotic Salgard at a concentration of 0.15 %, and group III - fed the same diet supplemented with 0.15 % of a herb mixture in an equal proportion (0.03% of each herb - rosemary, thyme, basil, oregano and cinnamon). At slaughter, material for histological examination was obtained from the ileum, the caeca, the liver and the kidneys of birds. Faecal content from the ileum and the caeca were submitted to microbiological analysis. The addition of Salgard in a concentration of 0.15 % to the diet of Pekin ducklings contributed to significant increasing the length of the villi intestinales (P<0.001) and diameter of intestinal glands (P<0.01) in the ileum and epithelial height (P<0.05) in the caeca, as well as with a reduction of pathogenic intestinal microorganisms in the birds that received the prebiotic and herb mixture.
