RESUMEN
In present experiment 288 day-old commercial broiler chicks were subjected to eight dietary treatments consisting of three replicates of twelve chicks in each replicate were reared for a period of 6 weeks in winter season. The dietary treatments includes: T0- Negative control, T1-control, T2-0.5 % Amla + 0.5 % Ashwagandha + 0.25 % Turmeric powder, T3-0.25 % Amla + 0.5% Ashwagandha + 0.25% Turmeric powder, T4-0.125% Amla + 0.5 % Ashwagandha + 0.25 % Turmeric powder, T5- 0.5 % Amla + 0.25 % Ashwagandha + 0.25 % Turmeric powder, T6-0.5 % Amla + 0.125 % Ashwagandha + 0.25 % Turmeric powder and T7-0.5 % Amla + 0.5 % Ashwagandha + 0.125 % Turmeric powder. Standard managemental practices were followed during the experimental period. Supplementation of phytogenic mixture consisting of 0.5 % amla and 0.5 % Ashwagandha with 0.25% or 0.125 % turmeric powder (T2 and T7) gave best results and improved the giblet percentage, eviscerated weight percentage and drawn percentage in winter season. The cost of production of drawn weight (`/kg) of broilers at six weeks of age was reduced as much as ` 10.23 (T2) and ` 9.48 (T7) in winter season. The study concluded that addition of 0.5 % amla and 0.5 % Ashwagandha with 0.25% or 0.125 % turmeric powder can be effectively supplemented as an alternative to antibiotics growth promoter in poultry ration in winter for improving the carcass characteristics and such ration was found more economical in comparison to that having antibiotic growth promoter
