通过在基础饲料中添加不同含量的枯草芽孢杆菌,制成枯草芽孢杆菌含量分别为0cfu/g,0.45×109 cfu/g、0.9×109 cfu/g、1.36×109 cfu/g和1.81×109 cfu/g的5种试验饲料,分别用以上5种饲料饲喂均重(19.0 ±0.5)g,均体长(8.2±0.3)cm草金鱼5d,评估了饲料中不同枯草芽孢杆菌添加量对草金鱼的毒害作用.结果表明:在基础饲料中添加枯草芽孢杆菌的量低于0.9×109cfu/g时,试验前期(72 h之前)对草金鱼的毒害作用表现不明显,而72 h后其死亡率才出现明显的差异(P＜0.05),而枯草芽孢杆菌含量高于0.9×109cfu/g的试验组中,整个过程中,草金鱼死亡率存在明显差异(P＜0.05).在本试验条件下,枯草芽孢杆菌对草金鱼...

In order to assess the toxic effects of different dietary of Bacillus subtilis on goldfish,Bacillus subtilis was added to Basic feed formulations at 0cfu / g,0. 45 × 109 cfu / g,0. 9 × 109 cfu / g,1. 36 × 109 cfu / g and 1. 81 × 109 cfu /g,respectively. Each diet of the five test feeds was fed to goldfish（ average weight： 19. 0 ± 0. 5 g,average body length： 8. 2 ± 0. 3 cm） for five days. The results showed that when the amount of Bacillus. subtilis added to the basic feed was less than 0. 9 × 109 cfu / g,at the period of early test（...
