Ammonia content in ileal digesta was significantly higher in comparison with other groups and in caecal digesta was significantly higher in group 6 in comparison with groups 1 and 2. Villi height was significantly higher (P<0.05) in groups 2, 3 and 6 compared to the control. Villi height to crypt depth ratio was significantly higher (P<0.05) in groups 5 and 2, but the most promising effects seem to be from combinations 3 and 4. In comparison with control: in groups 2, 3 and 5 higher ALT, glucose and triglyceride; in groups 3, 4 and 5 higher total protein and cholesterol; in group 4 higher albumin and in group 6 higher BUN, were found. Generally, used eubiotic preparations affected gut morphology and some blood parameters but did not affect microbiota, pig growth or feed utilization.
