本试验旨在研究饲粮中添加枯草芽孢杆菌( Bacillus subtilis,BS)对石门土鸡生长性能、屠宰性能、血清抗氧化指标和肠道形态的影响。选取540只55日龄、体重[( 0.75±0.02) kg]相近的健康石门土鸡母鸡,随机分成3组,每组6个重复,每个重复30只鸡。对照组饲喂基础饲粮,试验组分别饲喂在基础饲粮的基础上添加300和600 mg /kg BS的试验饲粮。预试期7 d,正试期28 d。结果表明: 1) 1 ~ 14 d时,与对照组相比,300、600 mg /kg BS组石门土鸡的平均日采食量( ADFI)和平均日增重( ADG)有提高趋势( P>0.05) ; 15 ~ 28 d和1 ~ 28 d时,各组间的ADFI、ADG和料重比( F /G)均无显著差异( P>0.05) 。2)与对照组相比,6...

The purpose of this study was to investigate the effects of dietary Bacillus subtilis ( BS) on growth performance,slaughter performance,serum antioxidant indexes and intestinal morphology of Shimen chickens. A total of 540 55-day-old healthy Shimen female chickens with similar body weight of ( 0.75±0.02) kg were randomly divided into 3 groups with 6 replicates per group and 30 chickens per replicate. Chickens in control group were fed a basal diet,and the others in experimental groups were fed the basal diet supplemented with 300 and 600 mg /k...
