Occurrence of concurrent infectious diseases in broiler chickens is a threat to commercial poultry farms in Central Ethiopia

Abstract

Commercial poultry production is one of the flourishing ventures of animal production in Ethiopia. It has been providing to the demands of proteins at least to the urban population, though concurrent health constraints are hampering its intended potential. This study reports the influence of infectious diseases in commercial broiler farms in central Ethiopia. In this study, clinical signs, gross lesions, laboratory tests (serology, bacterial culture, histopathology and parasitology) and farm management data were used to identify major causes of outbreaks in an age specific manner in broiler chickens in three poultry farms in Debre Zeit, Central Ethiopia. The outbreaks detected in the farms were due to mycoplasmosis, salmonellosis, colibacillosis, coccidiosis and infectious bursal disease. It is observed that the occurrence of concurrent diseases in the farms significantly affects the productivity and health status of broilers. The risk factors that predispose birds to the various infections in the different farms studied were also recorded. In addition, recommendations were also provided.
