This study was conducted to investigate the effect of dietary wormwood powder (Artemisia montana Pampan； WP) supplementation on growing performance and fecal nexious gas cmission in weanling pigs. One hundred and twelve pigs were alloted into four treatments and offered for 4 weeks one of the diets supplemented with 0％ (control), 0.5％ (0.5), 1.0％ (1.0) and 2.0％ (2.0) WP. Each treatments has four replicate with 7 pigs per replicate. ADG, ADFI and F／G were improved by 1.0 and 2.0 WP supplementation during 0d ~ 14d feeding. Feed intake of 1.0 WP diet was higher (P＜0.05) than any other diet during 15d ~ 28d feeding. But there were no differences among the other treatments in the weight gain and feed conversion. During the whole feeding period, daily weight gain and feed intake of pigs fed 1.0 and 2.0 treatments were higher than those of pigs fed control and 0.5 diet. DM digestibility was significantly (p＜0.05) higher in weanling pigs fed 0.5, 1.0 and 2.0 WP than that of the control. The protein digestibility was significantly improved in 1.0 wP treatment and the phosphorus digestibility was improved in 2.0 WP treatment. Excretion of nitrogen and phosphorus was significantly (P＜0.05) decreased by 2.0 treatment than control. Emission of fecal ammonia after 48 hours storage in viny1 bag dramatically decreased by all the treatments except control. However, there was no statistical difference in fecal hydrogen sulfide emission among treatments. In conclusion, this study suggested that the dietary 1.0∼2.0 supplementation of WP can improve productivity of pigs decrease fecal NH_(３) and H_(２)S gas emission.
