We investigated the effect of Lactobacillus fermentum AD1 (canine isolate) on selected intestinal microbial groups, weight gain, organic acids, haematology, glutathione peroxidase and phagocytosis of leucocytes in 2-days-old Japanese quail. The results demonstrated that the 4-day long application of this strain significantly increased the population of lactic acid bacteria, lactobacilli and enterococci, in faeces and caecum and significantly decreased the counts of E. coli in faeces. The daily weight gain increased by 14%. Although intestinal pH of both groups of birds was similar, the concentration of lactic acid was significantly increased in the experimental group. The concentration of other organic acids (acetic, acetoacetic, formic, succinic, valeric, propionic, butyric) as well as blood glutathione peroxidase was not influenced. The index of phagocytic activity of leucocytes was significantly improved.
