A total of 180 day-old quail chicks were randomly divided into 3 groups each containing 60 chicks. Each group was randomly divided into 5 subgroups each containing 12 chicks. The chicks were fed with corn, soybean meal and full-fat soybean based rations for 35 days. While the control group was fed with basal ration, the experimental groups were fed with probiotic supplementation at 0.1 g/kg and 0.3 g/kg doses, respectively. At end of the experiment, the use probiotics in quails did not affect initial LW, final LW, LWG, FI and FCR. The increase in dietary probiotic, MDA, GSH, SOD, CAT and GPx exhibited a linear response. However, ceruloplasmin, albumin, total protein and globulin were not affected by the addition of probiotic. Significant linear responses in asetic acid, isocaproic acid and SCFA were observed with the gradued level of probiotic. However, a significant quadratic response in the caproic acid was observed. Therefore, the effective dose for caproic acid was 0.1 g/kg. There were no significant differences in acetic acid, propionic acid, butyric acid, isobutyric acid, valeric acid, isovaleric acid and BCFA concentrations for quails fed with different levels of probiotic. In conclusion, diets containing Lactobacillus farciminis in quail can be used to improve the antioxidant capacity and intestinal health.
