This study was conducted at Agricultural Research Center / Scientific Research Commission, from 1/7 to 12/8 2025 to investigate the Effects of dietary inclusion of Schanginia arbuscula powder at three levels (5, 10 and 15%) on growth performance, mortality and live enzyme in broiler chickens.In the present study, day-old broiler chicks were randomly allocated to four dietary treatments, with three replicates per treatment and 75 birds per replicate. The birds were reared in floor pens within a single hall under identical standard environmental and nutritional conditions, and feed and water were provided ad libitum throughout the experimental period. The evaluated parameters were recorded on a weekly basis. Three inclusion levels of Tartae plant powder (Schanginia arbuscula) were incorporated into the diet prior to pelleting as follows: 5% in T2, 10% in T3, and 15% in T4, while T1 remained without supplementation and served as the control treatment. A completely randomized design (CRD) was adopted in the present study to evaluate the effect of four dietary treatments. Statistical analysis of the measured parameters was performed using the SAS software package. The results demonstrated that treatment T2 was superior to T3, T4, and the control (T1) in terms of weekly body weight. Regarding body weight gain, T2 outperformed the other Schanginia arbuscula supplemented treatments; however, no significant difference was observed when compared to the control group. With respect to feed conversion efficiency, T2 exhibited the most favorable performance throughout the study period. In contrast, treatment T4 achieved the most favorable outcome in terms of mortality rate, recording the lowest percentage compared with the other treatments, whereas the control group (T1) exhibited the highest mortality. Treatment T4 also showed the most pronounced improvement in liver enzyme activity, as it recorded the lowest serum levels of AST and ALT, followed by T3 and then T2, while the control treatment displayed the highest activity of these enzymes. No statistically significant differences were observed among the treatments with respect to feed intake throughout the experimental periods. Conclusion: This study clearly demonstrates the positive effects of dietary supplementation with Schanginia arbuscula plant powder on productive performance. The inclusion of this plant powder in the diet significantly improved growth performance, reduced mortality rates, and enhanced liver enzyme activity, indicating its beneficial role in improving physiological and productive efficiency.
