Phytogenic feed additives play an important role in broilers' nutrition, contributing to the improvement of the performance and quality of meat. The study aimed to evaluate the effect of Ginger (Zingiber officinale) and Cinnamon (Cinnamon zeylanicum) on broiler chicken production, fatty acid profile, and meat quality. In the present study, 140-day-old Vencob-400 broiler chicks were divided into 7 groups, including the control group (with no additives, T0), and T1 to T6 groups receiving varying concentrations of cinnamon and ginger. Accordingly, the chickens’ diet in T1 was supplemented with 1.0% cinnamon, T2 with 2.0% cinnamon, T3 with 3.0% cinnamon, T4 with 1.0% ginger, T5 with 2.0% ginger, and T6 with 3.0% ginger, all calculated based on dry matter. The carcass traits, weight of immune organs, organoleptic tests, and fatty acid profile of meat (breast and thigh) were recorded after the age of 42 days. The findings indicated that the breast and thigh had the highest organ weights in group T4 compared to other groups, however, the neck, back, drumstick, wing, and heart were not affected. The inclusion of 2% cinnamon (T2) and 1% ginger (T4) in the diet, significantly enhanced the color, texture, flavor, juiciness, and overall acceptability of the meat, compared to the diet of the control group. Adding a supplement of 2% cinnamon or 1% ginger powder to the diet of broiler chickens significantly decreased the percentage of total saturated fatty acid and increased the total unsaturated fatty acid (breast and thigh). The improvement in fatty acid composition is beneficial for the quality of the broiler meat. Based on these findings, it is recommended to supplement the diet of the broiler with either 2% cinnamon or 1% ginger powder to improve the carcass parameters and quality of the meat.
