The experimental design consisted of 5 dietary treatments: 1) a control diet without supplementation; 2) a diet with Biomin®IMBO at a level of 0.1 kg/100 kg feed; 3) a diet with Biotronic at a level of 0.4 kg/100 kg feed; 4) a diet with a Biomin®IMBO and Biotronic combination at levels given above; 5) a diet with avilamycin at a level of 10 mg/kg feed. Birds consuming diet supplemented with Biomin®IMBO, Biotronic and the combination of Biomin®IMBO and Biotronic, had a significantly (P<0.05) higher duodenal villus height. Single use of Biomin®IMBO and Biotronic also caused significantly higher jejunal (P<0.05) villus height. No significant differences in serum parameters were found among groups according to dietary supplements. No beneficial effect of dietary supplements on growth performance, feed intake, feed efficieny and absolute and proportional organ weights could be observed. The beneficial effects of such supplements could be more evident in other circumstances, like stress.
