摘  要：
选择健康、产蛋均匀的45周龄尼克珊瑚粉蛋鸡540只,随机分为3组,每组6个重复,每个重复30只鸡,其中两个组为试验组,另一组为对照组。采用单因子试验设计,试验组分别在基础日粮中添加250、500mg/kg的枯草芽孢杆菌制剂,对照组饲喂基础日粮,进行为期4周的试验,研究日粮中添加枯草芽孢杆菌制剂对产蛋鸡生产性能、蛋品质及营养物质消化率的影响。结果表明:①在蛋鸡日粮中添加枯草芽孢杆菌制剂具有改善料蛋比、降低死淘率、显著降低鸡蛋破损率(P<0.05)、提高个蛋重和蛋壳厚度的趋势。②蛋鸡日粮中添加枯草芽孢杆菌制剂显著提高了日粮粗蛋白和有机物消化率(P<0.05)。

摘  要：
An experiment was conducted to investigate the effects of a dried Bacillus subtilis culture on production performance,egg quality and nutrient digestibility of layers. 540 45-week-age layers were randomly divided into 3 groups with 180 layers in each group. Layers in group 1 were fed a control diet. The other two groups were fed the diet added 250,500 mg/kg Bacillus subtilis culture,respectively. Four weeks later,the results showed that the number of damaged eggs of layers was significantly decreased (P<0.05) when Bacillus subtilis culture was added to the diets. There was a tendency of improving egg weight and decreasing feed conversion ratio and mortality of layers during the experimental period. Meanwhile, the digestibilities of crude protein and organics of experimental group were significantly increased than that of control group(P<0.05).
