The Study was designed to know the effect of black cardamom (Amomum subulatum) on the health and productivity of poultry, which may have positive effects on poultry. 180 unsexed broiler (Rose 308) were divided into three groups: the first group was T0 (control group), the second group T1 had 0.2% Indian black cardamom added to their ratio, and the third group T2 had 0.4% Indian black cardamom added to their ratio.The experiment was conducted at a private poultry farm in the Al-Kamaliyah area 15/11/2025  The study showed a significant increase among the groups (P = 0.012) regarding body weight. Group T1 showed the highest body weight, followed closely by T2 compared with T0. No significant difference was observed between T1 and T2. The weights were as followsT₂(2076.33),T₁( 2062.53)than T₀(1939.27).The statistical results for the rate of weight gain also showed a significant increase among the groups (P = 0.007). Groups T1 and T2 demonstrated high significant in weight gain compared to T0, while the difference between T1 and T2 was not statistically significant.T0(531.47),T1(652.53)and T2(66.33).The rate of feed consumption, the results showed that feed consumption reached its highest levels across all groups, with T1 recording the greatest consumption, followed by T2, whereas T0 remained comparatively lower, In the fifth week, a highly significant difference was detected (P = 0.000). T1 (910±19.354) and T2 (898±10.499) demonstrated higher feed consumption compared with T0 (800±14.15).On other hand feed conversion efficiency showed that group T2(1.39) performed best compared to groups T1(1.50) and T0(1.59). The study concluded the Indian black cardamom plant has the ability to positively influence the productive traits of broiler chickens ,thus enhancing the positive impact on the poultry industry. The results also showed significant differences in the growth of harmful bacteria when culturing E. coli T0(77.20),T1(36.60) and T2(41.40).While Lactobacillus in T0 (28.00),T2( 52.00) and T2(124.00).
