[Objective] This study aimed to investigate the treatment efficacy of tradi- tional Chinese veterinary medicine mycoplasma gatlisepticum infection spray against experimental mycoplasma gallisepticum infection. [Method] Experimental chickens in- fected with mycoplasma gallisepticum were used as models to investigate the treat- ment efficacy of different doses of traditional Chinese veterinary medicine mycoplas- ma gallisepticum infection spray. [Result] Medication with traditional Chinese veteri- nary medicine mycoplasma gallisepticum infection spray for continuous 5 d showed certain treatment efficacy against mycoplasma gallisepticum infection. The relative weight gain rate of 0.5 and 1.0 g/m3 dose groups was significantly higher than the infection control group （P〈0.01）; the cure rate of mycoplasma gallisepticum infection spray groups was significantly higher than the infection control group （P〈0.01） and showed no significant difference compared with Taimiaoling control group （P〉0.05）; the mortality rate showed no significant difference among various groups （P〉0.05）, indicating that traditional Chinese veterinary medicine mycoplasma gallisepticum in- fection spray has relatively ideal treatment efficacy against mycoplasma gallisepticum infection. [Conclusion] This study provided reference for treatment of chickens infect- ed with mycoplasma gallisepticum.
