The study in the text was carried out in broiler chickens to investigate the inclusion of black pepper (Piper nigrum) and coriander (Coriandrum sativum) at graded levels (0.5%, 1.0% and 1.5% black pepper; 1.0%, 2.0% and 3.0% coriander) either alone or in combination as an alternative to body weight (g). A 42-day feeding trial followed by a metabolic trial was conducted under standard feeding and management conditions on 360 day-old Vencobb broiler chickens randomly divided into 10 treatment groups (T₁-T₁₀) with three replicates of 12 chickens each. Feeding was done according to 'ICAR (2013) standards. The total mean daily gain in treatment groups T₁ (control), T₂, T₃, T₄, T₅, T₆, T₇, T₈, T₉ and T₁₀ were recorded as 51.83, 52.15, 58.51, 57.73, 54, 68, 59.30, 55.75, 55 54.88, 54.52 g, respectively. Statistical analysis of the data revealed a highly significant (p<0.01) effect of black pepper and coriander administration in II. to VI. week and a significant (p<0.05) effect in week I.
