Effects of Cinnamon (Cinnamomum Zeylanicum) and Turmeric (Curcuma Longa) Powder on Performance, Enzyme Activity, and Blood Parameters of Broiler Chickens Under Heat Stress

Abstract

The effect of cinnamon and turmeric powders on performance, and blood parameters of broiler chickens under heat stress were investigated. 200 one-day-old male chicks (Ross 308) were used in a completely randomized design with four treatments and five replicates with 10 birds in each replicate. All birds were treated with heat stress (32οC) and were either fed no any supplement (control), or 0.5% turmeric, 0.5% cinnamon, and a blend of cinnamon and turmeric (0.25% each) when they were 25 to 42 days of age. We found that supplementation of turmeric, cinnamon, and their combination increased feed intake and body weight gain compared to control birds (P 0.05). In conclusion, dietary supplementation of cinnamon and turmeric either alone or together improve the performance of broiler chickens under heat stress by reducing lipid peroxidation.
