This study was carried out in the farm of Animal Resources dept. University of Mosul. A total of (480) day old chicks were used (cobb 500) in four treatments with two replicates per treatment (40 chicks/rep.). The experimental dietary treatments were T1: 0% vetch (control), T2: 9.4 and 8.3%, T3: 17.3 and 16.5% and T4: 28.1 and 24.8% raw common vetch in the starter and finisher diets resp. All diets were iso-caloric and iso-nitrogenous. The results showed a significant decrease (P≤ 0.05) in everage live body weigh at 8 weeks of age, daily feed consumption also decreased as the level of vetch increased in the diets, birds of T4 showed a significant reduction of dressing percent, packed cell volium, serum total protein, glucose, triglyceride and uric acid. It is also revealed that inclusion of common vetch in the chick diets caused a significant increase in the relative wights of liver, gizzard pancreas and mortality. It is concluded that raw common vetch were not recommended to inclusion in broiler diets.
