Objective: Ectoparasitism is an important factor associated with the poor production of indigenous chickens. The present study was undertaken to estimate the prevalence and ectoparasite diversity in indigenous chickens of the Dalahu region in the western part of Kermanshah province, Iran.


Methods: A total of 600 indigenous chickens (250 roosters and 350 hens) were randomly examined for the presence of different ectoparasites over the period April to September 2011. Ectoparasites were collected from different parts of chicken body using a hand lens, magnifying glass, and flashlights. The samples were preserved in 70% alcohol and cleared in lactophenol.


Results: The overall prevalence of ectoparasites was 52.8% (66% hens and 34.4% roosters) (p<0.001). Mixed infestation was noted in 70.34% of the chickens. The prevalence was significantly higher in young (66.3%) animals compared with older animals (39.33%) (p<0.001). Five species of ectoparasites were identified: Menopon gallinae (35.3%), Menacanthus stramineus (26.7%), Argas persicus (19%), Dermanyssus gallinae (11%), and Echidnophaga gallinacea (the “sticktight flea”) (8%).


Conclusion: The results of the present investigation reveal that ectoparasite infestation is prevalent in this area. Further studies are recommended to evaluate the effects of the ectoparasites on indigenous chicken health and production in the region.
