Insufficient pre-slaughter fasting leaves serious amount of feed-like contents (designated here as un-fasted stomach spent feed, USSF) in the eviscerated pig stomach. This study was intended to evoke economical and environmental seriousness of USSF discharge by estimating its value as pig feed. For finishing pigs feeding trial, three levels (0, 5, and 10%) of USSF were blended with pig feed to prepare control and two treatment diets, respectively. A total of 42 (21 males, 21 females) crossbred (Landrace ${ imes}$ Yorkshire ${ imes}$ Duroc) finishing pigs weighing $81.5{pm}8.0$ kg were employed to 28d feeding trial and in vivo digestibility trial by $Cr_2O_3$ indicator method with 7 males and 7 female pigs per treatment. In vitro total tract digestion of USSF showed 70.5% and 57.6% of DM and OM digestibilities, respectively which were poorer (p<0.05) than those of pig diet. There were no differences in body weight gain, daily feed intake and feed conversion ratio among treatments although 10% USSF substitution exerted relatively poor performance. In vivo apparent digestibilities of diets containing USSF 5% and 10% were lower (p<0.05) than that of 100% pig feed. There were no differences (p>0.05) in dressing percentage and carcass grade among treatments. Results of this study showed that 5% USSF substitution in finishing pigs diet did not exert any disadvantage in terms of production performance and carcass grade. This study implied that un-fasted slaughter causing excessive excretion of USSF should be avoided. If not avoidable, the USSF should not be wasted in abattoir but could be recycled as pig feed.
