摘要
为开发安全、无毒副作用、不产生耐药性和在动物体内无残留的饲料添加剂,采用酶制剂、酸制剂、有机铬、小肽、甜菜碱辅以多维,配制成新型绿色饲料添加剂,结果显示,研制的绿色饲料添加剂能使肉鸡日增质量提高7%,与对照相比料肉比降低了8.6%(P<0.05),抗生素使用量减少66%。同抗生素类添加剂相比,死淘率降低0.97个百分点(P<0.01)。
Green feed additives which are safe, have non-toxic side effects, no drug resistance and no residual feed additives in ani- mals were developed. The results showed that the average daily gain of broilers which were feed with the green feed additives was in- creased by 7%, compared with control treatment the ratio of feed to gain was cut down by 8%（P〈0.05）, the usage amount of antibi- otics was reduced 66%. Compared with antibiotic additives, the mortality rate was decreased by 0.97 percent （P〈0.01）.
