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。
3% wormcast was added into the basic ration of the AA broiler. The experiment was conducted in the same henhouse, and all the broilers were raised in the same immunity program. 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.
