This study has been carried out to evaluate the factors affected on feed conversion ratio in broiler farms in the Kermanshah province. First, 65 broiler farms out of 745 were selected, using stratified random sampling method. The crud data were collected by a designed questionnaire and the data were analyzed using SPSS ver 10 software package. The results indicated that the average of feed composition on the (0-21) Days as DM,CP, CF, EE, STR, SUG , Ca , P, Ash , OM , ME and T.V.N. were respectively 88.02, 23.27, 4.12, 1.84, 33.09, 5.23, 1.33, 0.71, 7.45, 92.72 percent, 2740 (Kcal/kg), 32.62(mg/100g/DM) and on the (22-42) Days 87.80, 20.03, 4.25, 2.42, 35.01, 5.42, 7.19, 1.3, 0.64, 6.87, 93.3 percent , (2740 kcal/kg) and 32.16(mg/100g/DM). The results also showed that the ratio of metabolizable energy to crud protein in different diets were lower (In starter diet 118 and in grower diet 135) than standard diet, (the NRC), resulted in low performance and increasing of feed conversion ratio. The total feed conversion ratio in studied farms during the period of the experiment was found to be 2.23 which was higher than standard for broiler. The mortality rate was also found to be %9.83 which was higher than recommended. The results indicated that the high concentration of Total Volatile Nitrogen (mg/100g/DM) caused high feed conversion ratio. The management factors including the level of literacy and technical knowledge also found to have a significant affect on the performance of the farm broiler. As a whole any efforts to upgrade the literacy levels and technical knowledge of the owner could result in better performance.
