Abstract
Helminthoses exerts negatively on the health and productivity of man and animals. This study was conducted to
investigate the incidence and risk factors associated with avian helminthoses in Osun state, Nigeria. Clinical
information was retrieved from the record archives of the state veterinary clinics. Case records between January
2006 and December 2015 were examined and relevant data associated with avian helminth disease were
extracted. Records on four thousand nine hundred and eighty bird types (2,088 turkeys; 1,476 layers; 384
cockerels; 12 ducks and 1,020 indigenous chickens) were used in the study. Faecal examination for the presence
of helminth eggs was carried out by qualified veterinarians and laboratory scientist using the simple floatation
method. An overall prevalence of 62.9% (3,132/4,980) was recorded. The year-specific rate for avian
helminthoses was highest in 2011 (95.5%; 503/528) and lowest in 2007 (2.0%; 1/48), while the month-specific
rate was highest in December (98.9%; 95/96) and lowest in October (15.2%; 84/552). There was a significantly
(p < 0.05) higher prevalence in adult birds compared to young ones, in female compared to male and during the
dry season compared to the wet season. Ducks (91.7%; 11/12) and turkeys (84.5%; 764/2088) were the bird
types with the highest prevalence rate. The high prevalence of avian helminthoses in the study area proves that
the disease is endemic. There is need to embark on a radical preventive measure to curtail the disease, for
improved productivity in the poultry industry in Osun state and Nigeria.
