SUMMARY
400 male broiler chickens of Hybro-type were used in this experiment. They were randomly distributed in 20 pens which were randomly allocated to 4 experimental rations that include: complete mash method with ground dura (Sorghum vulgare); -complete mash with unground dura; free choice with ground dura; and free choice with unground dura grains. At the end of the experiment which lasted for nine weeks, the birds were slaughtered and the different parameters were studied.
No significant difference on total feed intake, feed efficiences and dressing percentage between treatments were found. However birds fed on free choice method with unground dura grains produced significantly (p < 0.05) higher body weight gain and eviscerated carcass weight as compared to others. Birds fed on both free choice and complete mash methods with unground dura grains produced significantly (p < 0.05) higher gizzard and crop percentage compared to others. No significant difference was found between the treatments with regard to the percentages of commercial cuts.
