In order to determine the feeding value of t:1e waste wood of Lentinus eddodes, the waste wood was milled and treated with $Ca(OH)_2$ and cellulase, then raw waste wood and the treated waste wood were fed to broiler chicken and Korean native goates. The results obtained were as follows; 1. The chemical composition of the waste wood was c. protein 2.26%. c. fat 2.57%. c. fiber 44.60 and c. ash 5.58%. No differences were detected between the raw waste wood and $Ca(OH)_2$ or cellulase treated waste wood in chemical composition. 2. In amino acid composition. no cystine and methionine was showed, but trace amount of Vitamin A, $B_1$, and $B_2$, and cholin chloride were detected. 3. Trichoderma viride SANK. No. 16374 was used to decompose the cellulose. 4. In broiler performance, when waste wood meal was subsituted for 5% wheat bran, no adverse effect was showed on weight gain, feed in take and feed efficiency. But $Ca(OH)_2$ and cellulase treated waste wood meal could be subsituted for 8% wheat bran. 5. In Korean native goat performance, feeding waste wood meal subsituted by 50% various bran (25% defatted rice bran and 25% barley bran) had no adverse effect on growth and feed efficiency. 6. Considering the above results, though the waste wood meal could be replaced to part of various bran, there was a bottle-neck to process the waste wood. The waste wood of Lentinus edodes was little feeding value on bed of ruminant.
