The aim of this study was to evaluate the efficacy of compound Chinese herbal extract of Rhubarb, Coptis chinensis and Codonopsison on growth performance, blood chemistry, carcass characteristics, and digestibility of nutrients in broilers. Broiler chicks (180 days old) were purchased and raised together for duration of 7 days (adaptation period). At the end of day 7, the chicks were weighed separately and one hundred twenty birds of average weight were indiscriminately chosen and divided into twelve replicates (10 birds per replication). These treatment replicates were further allocated to four main treatments labelled as T1, T2, T3 and T4. The treatment T1 (control) was delivered simple water without any additional supplementation. While, treatment T2, T3 and T4 were supplied water fortified with herbal extract of Rhubarb (4%), Codonopsis (2%) and Coptis chinensis (6%), with a concentration of 40 mL/L, 15 mL/L and 25 mL/L, respectively. The finding of study revealed that addition of Rhubarb leaf extract exhibited enhanced blood chemistry, digestibility of nutrients, performance, and carcass characteristics with better profit margin as compared to all other treatments including control group. Steadying of blood metabolites lead to enrich digestion of feed nutrients. In conclusion, the addition of Rhubarb extracts in broiler feed suggested as an economical and effective growth enhancing agent devoid of any residual effects such as antibiotic.
