Statistical analysis revealed differences among treatments relative to effect on body weight, feed consumption, feed conversion efficiency and total protein efficiency. The highest body weight gain was noted among the birds fed with 12.5 percent whole rice (WR) and 12.5 percent rice bran (RB) as replacement of corn. The lowest feed consumption was Treatment 5 (50 percent WR and 50 percent RB) which was significantly different from the other treatments. Meanwhile, the highest feed consumption was noted among birds fed with commercial broiler mash. The feed conversion efficiency in the control lot was statistically lower than the other treatments, indicating that more feed is required to produce a unit body gain in weight. The most efficient in feed conversion was Treatment 3 (25 percent WR and 25 percent RB). It was found that the total protein efficiency in Treatment 5 was significantly higher than the other treatments, indicating its better quality compared to the other rations. Statistical analysis also indicated that dressing percentage, feathering ability and breast fleshing of birds were not significantly different among treatments. The mortality encountered were mostly due to improper hatchery management, stress, crd, and not related to treatments. Feed cost per kilogram of broiler produced in the control treatment was statistically higher than the other treatments, reflecting the most expensive cost to produce a kilogram of broiler. Meanwhile, the highest return on investment in this experiment was found in Treatment 4 (37.5 percent WR and 37.5 percent RB), indicating the best performance to effect the best rate of return. Finally, the birds fed with 37.5 percent whole rice and 37.5 percent rice bran as replacement of corn (Treatment 4) was better than the other treatments in terms of body weight, feed conversion efficiency, cost of feed, and feed cost per kilogram of broiler produced.
