中文摘要：

在基础日粮中加入3%的蚯蚓粪产品饲喂AA肉仔鸡。对照AA肉仔鸡饲喂基础日粮,试验结束后统计饲料消耗量、死淘鸡数、腹泻发生情况,计算经济效益。结果表明,用蚯蚓粪产品做肉鸡的饲料添加剂,添加组与对照组相比,腹泻率下降74.2%,差异极显著（P〈0.01）;鸡舍中的氨气下降31.4%,差异极显著（P〈0.01）;同时可以使鸡的体重提高10.3%,鸡粪含水量下降5.5%,使生产1 000 kg活鸡的成本降低289.4元,提高了肉鸡饲养的经济效益。

The feed consumption, quantity of dead broilers and diarrhea broilers were counted. Results showed that the diarrhea ratio and ammonia content of the wormcast group decreased 74.2% and 31.4% （P〈0.01）respectively. At the same time, the weight of broiler enhanced 10.3%, and the the moisture decreased 5.5% in the experiment group. The broiler production cost of 1 000 kg decreased 289.4 yuan（RMB） after the wormcast was used.
