选用80只罗曼白色蛋鸡，研究了枯草芽孢杆菌和菊粉单独或联合添加对64 ~ 75周龄产蛋性能、蛋壳品质、胫骨性状、钙沉积、小肠形态和微生物区系组成的影响。将母鸡随机分为4个处理组，每个处理5个重复，每个重复4只母鸡。试验组分别饲喂基础日粮（对照）、基础日粮加1 g/kg B。枯草芽孢杆菌（2.3 × 10（8）cfu/g）、基础饮食加1 g/kg菊粉、或基础饮食加1 g/kg B的合生素组合。枯草芽孢杆菌（2.3 × 10（8）cfu/g）和1 g/kg菊粉。膳食补充B。枯草芽孢杆菌、菊糖或合生素提高（P
Eighty Lohmann White laying hens were used to investigate the effect of dietary inclusion of Bacillus subtilis and inulin, individually or in combination, on egg production, eggshell quality, tibia traits, Ca retention, and small intestine morphology and microflora composition from 64 to 75 weeks of age. Hens were randomly distributed into 4 treatment groups, with 5 replicates per treatment and 4 hens per replicate. Treatment groups were fed basal diet (control), basal diet plus 1 g/kg B. subtilis (2.3 x 10(8) cfu/g), basal diet plus 1 g/kg inulin, or basal diet plus a synbiotic combination of 1 g/kg B. subtilis (2.3 X 10(8) cfu/g) and 1 g/kg inulin. Dietary supplementation of B. subtilis, inulin or synbiotic improved (P
