Five years Retrospective Study of Avian Coccidiosis in a Veterinary Clinic Bukuru Plateau State Nigeria

摘要

This study was conducted to evaluate the incidence of avian coccidiosis and its associated various risk factors such as age,type of birds and season in a private veterinary clinic in Bukuru,Plateau State Ngeria.A total of 9406 cases during 2013–2017 were analysed and 1556 of them were positive for coccidiosis.There are several reports on the prevalence of avian coccidiosis by previous researchers;however,in this study we evaluated the prevalence of avian coccidiosis in the study area and its economic impacts.Total prevalence of 12.14%in 2013,18.78%in 2014,18.21%in 2015,16.82%in 2016 and 19.07%in 2017 were reported.An overall prevalence of 85.02%was recorded.The average prevalence of coccidiosis based on this five years study is 17%.The association between coccidiosis and age of the birds was determined and age 5-8 weeks becomes most effective period with wet season having high percentage prevalence of coccidiosis.Based on the type of birds,coccidiosis is prevalence almost in equal proportion in both broilers and layers.The losses caused by avian coccidiosis could be both direct and indirect components which may include the cost of control measures,inadequate good hygiene practices,production losses and lack of prophylaxis treatment.The control of avian coccidiosis can be achieved through good sanitary measures by avoiding water spillage on the pen floor,overcrowded stocking density,the use of prophylaxis-anticoccidials and proper good vaccination practices.
