In order to determine the substitution level of pig manure fermentation feed(PMFF) for finishing swine, a feeding trial was conducted for 60days with a total of 160 herds of three-way crossbred among Landrace × Large White × Duroc. The treatment was divided into 0, 20, 40, and 60% according to the intake level of PMFF. Results obtained are summarized as follows; 1. In the chemical composition of PMFF there seas no change in the contents of nutrients before and after fermentation. Fermentation processing eliminated the specific odor of pig manure. 2. The daily gains of the treatment that used 0, 20, 40, and 60% of PMFF were 737, 672, 640, and 508g, respectively. Daily gains were depressed as the level of PMFF increased but there was no significant difference among treatments. 3. Feed intake per herd fed 0, 20, 40, and 60% of PMFF were 200.69, 200.41, 234.77, and 207.90Kg respectively. 4. Feed efficiency fed 0, 20, 40, 60% of PMFF were 4.54, 4.97, 6.11, and 6.82 respectively It was found that the feed efficiency was depressed as the level of PMFF increased in the: ration. There was significant differency at 5% level between the treatment fed 0% to 20% and 40% to 60%. 5. Carcass evaluation data showed no definite difference among treatments. 6. In the economical analysis, feed post required per Kg of body weight gain was increased as the intake level of PMFF increased.
