摘 要:探讨了 EM制剂对 AA鸡的生长性能以及鸡粪除臭的影响。试验对象为经过共同饲养 1 8日龄的 AA肉鸡 ,进行初次称重 ,并按其体重交叉分组法均匀分为五组 (CK对照组、A、B、C、D试验组 ) ,对照组饲料不添加 EM制剂 ,试验组 A、B、C三组添加 2 / 1 0 0 0由华南农大动科系生态实验室提供的 EM制剂 ,D组添加 2 / 1 0 0 0台湾产亚罗康商品活菌制剂。整个实验期为 2 2 d。结果表明 ,EM制剂不能使鸡的增重、屠宰率、全净膛率有明显的提高 ,但能增强鸡对疾病的抵抗 ,能提高成活率和饲料报酬 。The effect of the EM (effective microoganism) on growth performance in AA chickens and stench elimination of the excreta was studied in this experiment. 18 days AA broilers were fed in same condition before the start of research. After first weigh, they were divided into five groups (Ck, A,B,C,D) according to the weight. The check group was not added the EM, but A,B,C groups were added the ME at 2/1000 rate that was made and supplied by the Ecology Laboratory of Animal science Department of south China Agriculture university, and D group was added the EM made in Taiwan. The whole experiment period was 22 days. The results showed that the EM could not obviously raise the weight gain, dressing percentage and so on, but increase the immunity, the livability and the feed conversion efficiency, and strickingly eliminate the stench of chicken excrement. \;
