초록

This study was carried out to investigate the feeding effects of dietary supplementation of fermented spent mushroom substrates (F-SMS) from Pleurotus eryngii with Bacillus subtilis CS21 and Saccharomyces cerevisiae on Hanwoo steers. The cellulase and xylanase producing bacteria, designated CS21, was isolated from freshly spent mushroom substrates from Pleurotus eryngii and used as probiotics to fermented spent mushroom substrates. Twenty Hanwoo steers were allocated into two feeding groups and assigned equally to two dietary treatments; Control (TMR) and TMR including 30% F-SMS (30% F-SMS TMR). Total gain and feed intake was significantly greater in the 30% F-SMS TMR than control (p<0.05), but carcass grades were not influenced by the experimental diets. Based on this study, fermented spent mushroom substrates from Pleurotus eryngii with B. subtilis CS21 and Saccharomyces cerevisiae is able to use as an ingredient feed in TMR for Hanwoo steers.
