ABSTRACT



The influence of the source of non-starch polysaccharides on microbial flora composition was examined (general number of aerobic bacteria, lactic acid bacteria, Escherichia coli, Enterobacteriaceae as well as yeast and mould) of hindgut of chickens, ducks and geese. When administering ground barley and rye in the concentrate mixtures for poultry, in place of maize their dietary fibre concentration was increased as well as the concentration of xylose and β-glucan. In the mixture whose main component was ground barley, a higher content of structural components was found, including hemicelluloses, in comparison to mixtures containing maize or rye.

Substituting ground maize with ground barley and rye in the mixtures for poultry, an increase of a general number of aerobic bacteria, lactic acid bacteria, Escherichia coli and Enterobacteriaceae was achieved in the content of ileum, colon and caecum. When feeding birds with ground barley, a decrease of yeast and mould amount was observed in the content of ileum and colon in comparison to a mixture with a high share of maize and rye grain. Independently of the diets applied, a larger general number of aerobic and lactic acid bacteria were observed in the content of the alimentary tract segments examined of ducks and geese in comparison to chickens. A smaller number of Escherichia coli, Enterobacteriaceae as well as yeast and mould were found in the intestinal content of ducks than in chickens and geese. SCFA correlation was negatively correlated, while pH reaction – positively, with structural carbohydrates share in the intestinal contents. A negative relation was found between the number of aerobic bacteria, lactic acid bacteria, Escherichia coli and Enterobacteriaceae and the concentration of hemicellulose in the birdsĺ intestinal content. The correlation between the number of bacteria in the intestinal content and SCFA [ ] concentration was positive, while it was negative in comparison to pH.

Key words: chickens, ducks, geese, cereal grain, alimentary tract, microbial flora.
