ROLE OF ADDING POWDERED SUMAC FRUIT, RED PEPPER, AND THEIR MIXTURE ON ORODUCTIVE PERFORMANCE OF BROILER CHICKENS

This study was aimed to investigate the role of adding powdered sumac fruit, red pepper, and their mixture on the productive performance of broiler chickens. The experiment was conducted in the poultry field, from October 26, 2021, to December 7, 2021 (42 days). Two hundred one-day-old non-sexed Ross 308 broilers were used, , with an initial average weight of 37 grams per chick.. The experiment consisted of four treatments with five replicates (10 chicks/replicate).During the experimental period, the birds were fed three types of balanced feed containing protein and energy. The starter feed was provided from day one to day 14. The grower feed was provided from day 15 to day 28. The finisher feed was provided from day 29 to day 42.Powdered sumac, red pepper, and their mixture were added at rates of 0.5%, 0.5%, and 0.5% to treatments T2, T3, and T4, respectively, while the control treatment (T1) received standard feed without any additives. Significant improvement was observed in live body weight in favor of the T4 treatment (mixture addition) and in total weight gain compared to the control treatment.
