This experiment was conducted in the chickens field of the Department of Animal Production - College of Agricultural Engineering Sciences - University of Baghdad, for the period from 25/2/2022 to 1/4/2022. To study the effect of partial substitution of fermented potato peeling powder instead of yellow corn in broiler food on productive performance, 231 (Ross 308) broiler chicks were used in the experiment, distributed randomly to seven treatments of 33 chicks/treatment, each treatment containing three replicates and each replicate containing 11 chicks, as the chicks were classified at the age of one day, as each reproduce included six males and five females, and the experimental treatments were as follows: The first treatment, T1: a comparison treatment containing yellow corn, at a rate of 48%, and the second treatment, T2, the third, T3, and the fourth, T4, in which fermented potato peels were replaced with kiwi juice At rates of 6, 12 and 18%, respectively, while the fifth treatment (T5), sixth (T6) and seventh (T7) included substituting fermented potato peels with the Iraqi probiotic, at rates of 6, 12 and 18%, respectively. Data were analyzed according to a completely randomized design (CRD). The features under study were recorded over three periods from 1 to 10 days begins phase, 11 to 24 days growth phase, and 25 to 35 days terminal phase according to the Ross 308 Production Manual. Data indicated There was a highly important decrease (P < 0.01) in treatment T4 and T7 compared to other treatments in average body weight, average weight gain, and food changed factor for different periods, while the replacement treatments of 6% and 12% fermented potato peelings with fortifier and kiwi juice did not differ significantly. with the comparison treatment. The treatments did not show significant differences in the amount of feed consumed in the different age stages of the study.
