The study was conducted to test the effect of Jerusalem artichoke (JA) in dry form on the digestive tract of broiler chicken. The birds were divided in seven groups. The feed ration of the first group chicken was without supplement, the other six groups – supplemented with additive JA and Lactobacillus reuteri in different concentrations. Two birds from each group were slaughtered at the trial beginning on the 7th , further – 28th and 42nd days of age. The content of ileum was bacteriologically tested for counts of lactic acid bacteria and Enterobacteriaceae . The results confirm that intestinal homeostasis is most favourably influenced by adding dried JA in 0.5 % concentration to the basic feed o r a symbiotic – dried JA in combination with 1• 10 8 Lactobacillus reuteri in 0.5 % concentration.
