| The study was conducted in terms of knowing the growth performance of broilers supplemented with Ginger and kalojeera and their effect on hematological parameters (TEC, Hb, ESR, PCV, and DLC). A total of 100 day-old Cobb 500 commercial broiler chicks were randomly divided into five groups (T0, T1, T2, T3, T4) and each treatment contain 20 broilers to carry out the work. The average initial weight of the chicks in all experimental groups was about the same. Weekly observations were recorded for live body weight up to 35 days and blood parameters of birds at day 14th, 21th and 35th days. The result showed comparatively better live weight in T4 which is treated with Kalojeera and Ginger having a satisfactory feed conversion ratio (FCR) of 1.68. The better feed conversion ratio (FCR) value was recorded by chicks fed diet supplemented with antibiotics in T1. The hematological parameters TEC, ESR, and DLC value of treatment group shows a significant difference, while Hemoglobin estimation does not show a significant difference from the control group. It could be concluded that Kalojeera and Ginger could act as growth promoters and alternatives to antibiotics in broilers.
