抗生素联合使用对肉鸡呼吸道综合症治疗效果的影响

选用四种针对呼吸系统的抗生素,通过对发病鸡群进行集中饮水投药,对不同成分的抗生素在肉鸡呼吸道综合症中的治疗效果进行评价。结果显示：鸡群饮用10%阿奇霉素和10%替米考星后,死亡率降低10%,采食量提高了24%;饮用泰妙菌素和多西环素,死亡率降低7%,采食量提高14%;饮用单纯的泰妙菌素后,死亡率降低5%,采食量提高5%。结果表明：抗生素有选择的联合使用能有效提高肉鸡呼吸道综合症的治疗效果,降低产生耐药性的可能,能防治肉鸡饲养管理过程中出现的病症,降低总体饲养成本,提高肉鸡生产的经济效益。

Effect of antibiotic combined use on the respiratory syndrome therapeutic results of the chicken

In this study,the four different composition antibiotics against respiratory tract infections were selected in order to evaluate the therapeutic effect on the respiratory syndrome of the chickens,through the drinking water to concentrate administration,the overall state of chickens after administration were observed.The results showed that chickens drinking 10% of azithromycin and 10% of tilmicosin,10% of the mortality rate was lower than before,the feed intake increased by 24%.Chickens drinking Tiamulin and doxycycline,the mortality rates reduced by 7%,the feed intake increased 14% over the previous.Chickens drinking Tiamulin simple,the mortality rate was 5% lower than before treatment,the feed intake increased by 5%.The result indicated that the selective combination of antibiotics for respiratory could improve effectively chickens respiratory syndrome therapeutic effects,and reduce resistance.It could control the breeding management of the disease,reduce overall feeding cost and increase economic efficiency of the chicken production.
