The purpose of this study was to investigate the effects of dietary Hermetia illucens powder on duck litter quality. One hundred twenty Pekin ducks (0 day old) were assigned to 2 groups (0% and 0.5% Hermetia illucens powder) with 3 replicates (20 ducks per replicate) for 42 days. Duck litter quality included moisture, pH, VBN, total nitrogen, ammonia, and temperature. Litter pH and VBN values were significantly affected by Hermetia illucens powder (p<0.05). However, moisture and total nitrogen values were not greatly influenced by the addition of 0.5% Hermetia illucens powder (p>0.05). At 21, 28 and 35 days, both 0.5% Hermetia illucens powder and controls had a great effect (p<0.05) on ammonia contents, except at 7, 14 and 42 days. In comparison to control, ammonia contents in groups with 0.5% Hermetia illucens powder were reduced from 16.9 to 41.8% as the days increased. Duck litter showed lower temperature by 0.5% Hermetia illucens powder compare to control. In terms of environmental managements, these results suggest that using 0.5% Hermetia illucens powder as feed additives improved litter quality and decreased ammonia contents.
