The present study investigated dietary inclusion effects of soybean oil at three levels (0%, 2% and 4%) and three sources of commercial bone meals (GBM, PBM and IBM) on the body weight, weight gain, feed consumption, feed efficiency, digestibility coefficient, calcium, phosphorus and ash contents of blood and bone in broiler chickens. Mean weekly feed consumption, average cumulative body weight, and average weekly body weight gain increased significantly (P < 0.01) in broilers fed soybean oil-containing diets, with T9 and T1 showing the highest (5058.27 g) and lowest (4117.88 g) mean total feed intakes. Mean cumulative body weight was uppermost (2168.33 g) in T6 while the lowermost value (1930.00 g) was recorded in T1. Likewise, T6 and T1 attained the highest (301.04 g) and lowest (273.77 g) average body weight gain, respectively. Maximum (2.38%) and minimum (1.04%) abdominal fat weight percentages were found in broilers fed a diet containing 4% soybean oil with GBM and those received no soybean oil with IBM, respectively. Yet, soybean oil-containing diet could improve the overall performance of broilers. Dietary inclusion of 2%-4% soybean oil-containing sources of bone meal led to better contents of ash, calcium and phosphorus both in the blood and bone. Therefore, 2%-4% dietary inclusion levels of soybean oil with GBM as the source of bone meal is recommendable as inferred by improved bone calcification and utilization of phosphorus and minerals in the broilers’ body.
