This study made an economic evaluation of duck using Houttuynia cordata (H. cordata) powder as feed additives after 6 weeks. A total of 300 ducks (Pekins) were randomly assigned to one of the three treatments (0%, 0.5% and 1% H. cordata powder), with 5 replicates of 20 ducks each. After 6-week feeding trial, an economic improvement in all the treatments was found in following order: T2 (1% H. cordata powder) > T1 (0.5% H. cordata powder) > control. The results suggested that the addition of H. cordata powder to duck diets provided significantly greater economic benefits, indicating sustainable environmental management of the duck industry.
