The current experiment was conducted to evaluate the effect of different types of probiotics on growth performance, carcass traits, intestinal microflora, and jejunal morphology of Japanese quail in comparison with Flavophospholipol antibiotic supplement. A total of 540 one-day old quail chicks were randomly divided into five groups with six replicates (18 birds per pen). The experimental groups included: a basal-diet as control, or the basal diet supplemented with 650 mg/kg Flavophospholipol antibiotic, 200 mg/kg Bacillus subtilis (4×10⁹ CFU/g), 200 mg/kg Bacillus coagulans (2×10¹¹ CFU/g), and 200 mg/kg Bacillus subtilis (4×10⁹ CFU/g)plus Bacillus coagulans (2×10¹¹ CFU/g). Inclusion of B. subtilis probiotic in the diet increased body weight gain (BWG) significantly from 22 to 35 d and from 1 to 35 d compared with control and antibiotic groups (P< 0.05). Also, the using of B. subtilis alone and B. subtilis plus B. coagulans in the diet significantly improved BWG and feed conversion ratio in the whole of study (1-35 d) compared to control group, whereas the use of antibiotics had no significant effect on these parameters compared with control group. The use of all additives resulted in increasing the relative weights of carcass and breast compared to the control group and the highest carcass weight was related to quails fed B. subtilis (P< 0.05). In comparison to the antibiotic group, the use of treatments containing probiotics increased lactic acid bacteria (P< 0.05). Probiotics especially B. subtilis significantly increased villus height of jejunum. However, birds receiving B. subtilis treatments had the highest ratio of villus height to crypt depth compared with antibiotic treatment. It could be concluded that probiotic strains, particularly B. subtilis, may improve growth performance, carcass traits, intestinal microflora, and jejunal morphology of Japanese quail and maybe a good alternative to antibiotics in the diet of quail.

进行本实验是为了评估不同类型的益生菌与黄酮磷脂的抗生素补充剂对日本鹌鹑生长性能，car体性状，肠道菌群和空肠形态的影响。将总共​​540只一天大的鹌鹑雏鸡随机分为五组，每组六只重复（每只圈养18只鸡）。实验组包括：以基础饮食为对照，或补充650 mg / kg黄磷磷脂抗生素，200 mg / kg枯草芽孢杆菌（4×10 ⁹ CFU / g），200 mg / kg凝结芽胞杆菌（2× 10 ¹¹ CFU / g）和200 mg / kg枯草芽孢杆菌（4×10 ⁹ CFU / g）加上凝结芽孢杆菌（2×10 ¹¹ CFU / g）。的夹杂物的枯草芽孢杆菌在饮食益生菌增加体重增益（BWG）显著从22至35 d和1至与对照和抗生素组相比35 d（P <0.05）。而且，与对照组相比，在整个研究（1-35 d）中，饮食中单独使用枯草芽孢杆菌和枯草芽孢杆菌加凝结芽孢杆菌可显着改善BWG和饲料转化率，而使用抗生素则无效果。与对照组相比，对这些参数的影响显着。与对照组相比，所有添加剂的使用均导致cas体和乳房的相对重量增加，最高weight体重量与饲喂鹌鹑有关枯草芽孢杆菌（P <0.05）。与抗生素组相比，使用含有益生菌的治疗会增加乳酸菌（P <0.05）。益生菌，尤其是枯草芽孢杆菌显着增加了空肠的绒毛高度。然而，与抗生素治疗相比，接受枯草芽孢杆菌治疗的鸟类的绒毛高度与隐窝深度之比最高。可以得出结论，益生菌菌株，尤其是枯草芽孢杆菌，可以改善日本鹌鹑的生长性能，car体性状，肠道菌群和空肠形态，并且可能是鹌鹑饮食中抗生素的良好替代品。
