[Objective] The aim was to explore effects of Bacillus licheniformis on production performance of pregnancy and lactation sows and the ammonia concentration in piggeries. [Method] Landrace × Lange sows before 30 d pregnancy were fed with basic feed added inocula and power of B. licheniformis, and effects of B. licheniformis on production performance of pregnancy and lactation sows and the ammonia concentration in piggeries were investigated. [Result] Compared with control,B. licheniformis could reduce the constipation ratio of sows,the mortality ratio of piglets and ammonia concentration in piggeries significantly. It could also improve the daily feed of sows and the diarrhea ratio of piglets significantly. [Conclusion] B. licheniformis can increase the production performance of sows and piglets effectively, improve the environment of piggeries and reduce environmental pollution.%[目的]探讨地衣芽孢杆菌菌剂和菌粉对妊娠及哺乳母猪生产性能和猪舍氨气浓度的影响.[方法]选用产前30 d的妊娠母猪(长×大)为试验对象,通过在基础日粮中分别添加地衣芽孢杆菌菌剂和菌粉,考察其对妊娠及哺乳母猪生产性能和猪舍氨气浓度的影响.[结果]与对照组相比,饲喂地衣芽孢杆菌后能显著降低母猪便秘率、仔猪腹泻率及猪舍氨气浓度,且对母猪采食量及仔猪死淘率等也有明显改善.[结论]在饲料中添加地衣芽孢杆菌能有效提高母猪及仔猪的生长性能,改善猪舍环境,降低污染.
