This study was conducted to investigate the effect of feed containing cinnamon and turmeric extract with peroxide oils on the growth performance, antibody titers, cecal microbial population, and jejunum morphology of broiler chickens. For the research, a completely randomized design was used using 300 one-day-old male broiler chickens of the Ross 308 strain for 42 days. Five treatments of six replicates each were utilized, which comprised 30 pens, each containing 10 chicks. The treatments included: 1) control group (a ration containing oil with natural peroxide value (less than 5mEq/kg), 2) positive control treatment (a ration containing oil with a high peroxide value (20mEq/kg), 3) treatment containing cinnamon extract (150mg/kg) along with a ration with a high peroxide oil (20mEq/kg), 4) treatment containing turmeric extract (150mg/kg) along with a ration with a high peroxide oil (20mEq/kg), and 5) treatment containing cinnamon extract (150mg/kg) and turmeric extract (150mg/kg) along with a ration containing oil with a high peroxide value (20mEq/kg). GLM procedure and Duncan's test (α=0.05) by SAS software were used for data analysis and to compare treatment' means, respectively. The effect of the experimental treatments on the body weight of broiler chickens in all rearing phases except the starter, antibody titers against infectious bronchitis and Gumboro disease, villus length, crypt depth, and Ratio of villus length to crypt width was significant (p<0.05). Findings indicated that the use of cinnamon and turmeric extract in rations containing oil with a high peroxide value improves production performance and flock health.(AU)
