The objective of this study was to evaluate the characteristics of duck litter in ducks fed diets containing Houttuynia cordata powder. One-day-old ducklings (Pekin) were randomly divided into two groups and fed a control or 1% H. cordata powder-containing diet for an experimental period of three weeks. The results showed that pH for 1-2 weeks and total nitrogen for 1-3 weeks in duck litter were affected by dietary treatments with 1% H. cordata powder (P < 0.05). For Volatile Fatty Acids (VFAs), there was no significant difference (P > 0.05) between ducks fed 1% H. cordata and control diets, as shown in the results for acetic acid and propionic acid in duck litter over three weeks; but, this was not the case for propionic acid at 3 weeks. The inclusion of 1% H. cordata powder in the diet had a the positive effect on increasing the total nitrogen and decreasing pH and VFAs in duck litter.
