An experiment was carried out to determine the effects of adding potato chips by-product (PBP) to Golden Montazh chick's diets (starter and finisher) on productive performance, carcass characteristics, and economic evaluation.
Five levels of PBP representing 0.0 (control), 2.5, 5.0, 7.5 and 10.0% were used during starter (0-6 weeks) and finisher (7-10 weeks) in five dietary treatments (T1-5). 225 one day old unsexed of Golden Montazh chicks were divided equally into 5 dietary treatments in 3 replicates of 15 chicks each. All birds are kept under the same condition. Feed and water were supplemented ad-libitum. Three birds from each treatment were randomly chosen at the conclusion of the experiment, slaughtered, and their carcasses were measured, and their meat samples were taken. Results revealed no significant differences between treatments in live body weight, body weight gain, feed consumption, or feed conversion ratio.
 The percentages of carcass and total edible parts (TEP) were increase significantly when chicks fed diets containing 7.5% PBP compare with control (T1); however, the percentages of liver, gizzard, heart, or total giblets hadn't affected by different treatments. Chemical composition of meat (protein, ether extract, and ash) as percentages on dry matter basic showed that ash% hadn't affected by different treatments, on the other hand, ether extract % increase significantly in all treated groups compare with control and the opposite was recorded in crude protein%. The results of economical evaluation showed that potato chips by-product could be included at 2.5 and 5% in chicks' diets to support and enhance economic efficiency.
Conclusion: From the present results it could be stated that adding potato chips by-product at inclusion rate of 5% to Golden Montazh diets as a replacement of yellow corn, would have a positive effect on economic efficiency without any adverse effect on productive performance or carcass traits.
