Cost of Coccidiosis

Coccidiosis continues to burden the poultry industry worldwide (1).  This disease is one of the most frequently reported disease worldwide and is present wherever poultry are raised (1,2).  The annual cost of coccidiosis globally is estimated to be approximately $2.4 billion (2).  However, each country and local city has different costs associated with coccidiosis.  The cost of coccidiosis and impact on poultry production is due to the cost of coccidial control (e.g. medication and vaccination), predisposition to secondary disease, sickness (e.g. decreased performance due to impaired growth rate, poor feed conversion or temporary reduction in egg production) and mortality (3).
