Replacement of Different Levels of Rapeseed Meal with Soybean Meal on Broilers Performance

This study was conducted to determine the replacement of different levels of rapeseed meal with soybean meal as protein source on broilers performance (7 to 49 day old). Experiment design consisted under completely randomized design of a 5 arrangement of dietary treatments with five replicates, a total of 375 (1-day-old) commercial broiler chicks (Ross-308) were randomly distributed into 25 groups consisting of 15 chicks per group. The treatments were (0.0, 4, 8, 12 and 16%) levels of rapeseed meal. The criteria used to assess were weight gain, feed consumption, feed conversion ratio and internal organs weight. Increasing of body weight between treatment in different levels of rapeseed meal and control group showed significant difference (p<0.05). Maximum weight gain belonged to treatment contain 8% and minimum weight gain belonged to treatment contain 16% rapeseed meal. Feed consumption between treatments in different levels of rapeseed meal showed significant difference (p<0.05). However, rapeseed meal had positive effect on feed consumption. Maximum feed consumption belonged to control group and minimum feed consumption belonged to treatment contain 16% rapeseed meal. Feed conversion ratio between treatment in different levels of rapeseed meal showed significant difference (p<0.05). Minimum feed conversion ratio belonged to treatment contain 16% rapeseed meal and maximum feed conversion ratio belonged to control group. There was significant difference between percentage weights of abdominal fat in different levels of rapeseed meal (p<0.05). But there was no significant difference between percentage weights of intestine, liver, pancreas and carcass yield of treatments (p>0.05).
