This study is to retrospectively determine the major conditions diagnosed for whole bird poultry carcasses presented at the Central Veterinary Laboratory for post-mortem. Post-mortem reports of whole bird carcasses presented from January 2009 to December 2013 were reviewed. Details collected and analysed for each report included the primary disease diagnosed, secondary infections, bird type, age, production system, farm flock size, farm location and season. Data was entered into SPSS descriptive studies and summary measures. Eight hundred and forty one (841) cases were reviewed during the study period. Bacterial diseases accounted for 380 cases (45.2%), 223 viral cases (26.5%) and 182 (21.6%) parasitic conditions. Non-infectious diseases were reported in 52 cases (6.2%). Collibacillosis (n=303, 79.7%) was the most common bacterial condition while IBD (n=108, 48.4%) was the most common viral condition. Coccidiosis (n=95, 52.2%) was the most common parasitic condition reported. Sample submission trends and distribution of production systems may have influenced the distribution patterns of diseases reported
