The present investigation was to determine the influence of dietary supplementation of Chrysopogon zizanioides, Mentha piperita, and Ocimum tenuiflorum on broiler production performance, body temperature, and intestinal histo-morphology. A total number of 160-day-old male broiler chickens (Cobb 400 strain) were employed in this investigation. A randomized design with four treatments and four replicates (each with ten birds) comprised the experiment. The baseline diet was referred to as control (T1). The basal diet plus 1% O. tenuiflorum, basal diet plus 1% M. piperita leaf powder, and basal diet plus 1% C. zizanioides root powder were given to the treatment groups T2, T3, and T4. Body weight gain, feed intake, feed conversion ratio, body temperature, offal weight, dressing percentage, and intestinal histo-morphometry (villi height, apical villi width, and crypt depth) were observed. Results from this study demonstrated that C. zizanioides root powder administration could increase cumulative body weight gain (2144 vs 2024, 2037, 1813g/bird), villous height (519 vs 464, 495, 322 µm), apical villous width (48 vs 34, 48, 33 µm), and crypt depth compared to control and other treatments. Ocimum tenuiflorum leaf powder-fed treatment group produced outcomes comparable to those of the control while having slightly higher feed intake than the control and other treatments. However, when compared to the control, the treatment-fed M. piperita leaf powder reduced body weight, feed consumption, villous height, apical villous width, and crypt depth. It might be determined that using 1% supplementation of C. zizanioides root powder will influence the effective broiler production performance and have healthier guts.
