The study evaluated the effects of different concentrations of POLTRON herbal extract in drinking water on broiler chicken performance and immune response. 200 one-day-old broiler chicks were divided into 4 groups, with one control group and three treatment groups receiving 0.5%, 1%, or 1.5% POLTRON. Productive performance was evaluated at 35 days. Results showed body weight gain and final weight were highest in the 0.5% and 1% groups compared to the control. Feed intake did not differ but antibody titers against Newcastle Disease virus were higher in the 1% and 1.5% groups. The 1% concentration showed the best results and is recommended for commercial use to improve productivity and profit
