Abstract;This study was conducted to investigate the nutritive value, palatability and feeding methods of silages made from the spent substrate (SS) after harvesting Nameko mushroom. Seventy % of ingredients of SS were corncob meal. The results obtained were as follows. In the experiment on the effects of additives on the fermentation quality of the silage made from SS, the production of lactic acid (LA) was improved by adding lactic acid bacteria (LAB) with cellulase (CEL) or with yeast. The addition of a mixture of LAB and molasses (MOL) showed slightly higher production of LA compared with adding LAB and CEL. In the experiment on the palatability of silages, control silage, the LAB+CEL silage and the LAB+MOL silage were not eaten at all by dairy cows. However, they were eaten when silages were mixed with concentrates (CON) or alfalfa hay cubes (AHC) that were highly palatable to dairy cows. Therefore, mixing silages with CON and AHC stimulated the appetite with reducing the repugnance caused by silages. In the experiment on digestion trial in vitro of silages, the LAB+MOL silage showed slightly higher dry matter disappearance (DMD) than control silage. Adding AHC to silages improved DMD further, increasing digestible energy and crude protein compared with silages alone. In conclusion, the spent substrate from Nameko mushroom cultivation was a fibrous feed available to dairy cows, provided that it was ensiled with lactic acid bacteria and molasses, followed by mixing with concentrates or alfalfa hay cubes before fed to animals. The amount of silages available to ruminants remains to be investigated. (author abst.)
