【 摘 要 】

Problem statement: One of the real problems that cause the economic prejudice in animalfarms yearly is parasitic diseases. To overcome these problems the use of antiparasitic drugs isnecessary. Ivermectin is a broad spectrum antiparasitic agent and different routes of its administrationsuch as injection, oral and pour-on were used. The aims of the current study were evaluation of theefficacy of ivermectin pour-on administration against natural Heterakis gallinarum infection in nativepoultry and also determination the prevalence rate of this parasite in Tabriz area. Approach:In thepresent study, 120 native poultry were investigated by Egg Per Gram of feces (EPG) feces test. Willismethod was applied for feces test and Mack-master slide method was used for counting nematodeeggs. After confirming the infection with worms, Ivermectin (0.5 mg kg⁻¹) pour-on was administratedto infected birds. Fecal examination was repeated in 1, 7, 21 and 28 days post treatment. Results:Results showed that total prevalence of Heterakis gallinarum infection was 21.66% in native poultry ofTabriz area. Efficacy rate of ivermectin pour-on was 59.14, 87.87, 97.65 and 99.57% in 1, 7, 21 and 28days respectively. Conclusion: In conclusion, the effect of this drug against Heterakis gallinarumresulted in reduction in egg count exceeded 98% (p<0.05), so this drug can be used in antiparasiticprogram in poultry. Further investigations are necessary to evaluate the drug effect on other nematodesand parasitic infections.
