Abstract

This study was carried out to investigate the feeding effects of the dietary supplementation of fermented spent mushroom (Pleurotus eryngii) substrates with Bacillus amyloliquefaciens CS47 and Saccharomyces cerevisiae (F-SMS) on growth performance and carcass characteristics of Hanwoo steers. Thirty two Hanwoo steers were allocated into two feeding groups and assigned equally to two dietary treatments; Control (commercial formula feed for Hanwoo steers and rice straw) and TMR including 30% F-SMS. The nutritional values of TMR including 30% F-SMS was higher crude protein (11.67%) and TDN (72.11%) than rice straw, but not significantly different from commercial formula feed (p<0.05). Feed intake was significantly greater in the TMR including 30% F-SMS than the control (p<0.05), but body weight gain and carcass grades were not influenced by the experimental diets. Based on this study, fermented spent mushroom (Pleurotus eryngii) substrate with Bacillus amyloliquefaciens CS47 and Saccharomyces cerevisiae is may be used as an ingredient of feed in TMR for Hanwoo steer.

본 실험에서는 새송이버섯 수확 후 배지 발효산물 첨가급여가 한우 거세우의 성장과 도체성적에 미치는 영향을 조사하기 위하여 비육기(17-24개월령) 한우 거세우 32두를 공시하여 30개월령까지 사양시험을 수행하였다. 공시동물은 30%의 새송이버섯 수확 후 배지 발효산물(F-SMS)이 첨가된 TMR 사료를 급여한 처리구와 시판 배합사료와 볏짚을 분리 급여한 대조구로 나누어 처리구별로 각각 16두씩 배치하였으며 한 우리($5{\times}6m$)당 4두씩 수용하였다. 30%의 F-SMS가 첨가된 TMR 사료의 영양 가치를 분석한 결과, 30%의 F-SMS가 첨가된 TMR 사료는 볏짚보다는 조단백질(11.67%)과 TDN(72.11%) 함량이 높게 나타났으나 시판배합사료와는 큰 차이가 없었다(p<0.05). 시험기간 동안 사료섭취량은 30%의 F-SMS가 첨가된 TMR 사료 급여구가 대조구보다 유의적으로 많았으나(p<0.05) 공시동물의 증체량에서는 처리구간에 큰 차이가 없었다. 육질등급에서는 30%의 F-SMS가 첨가된 TMR 사료 처리구(100%)의 1등급 이상 출현율이 대조구(87.5%)보다는 높게 나타났으나 육량등급에 있어서는 처리구별로 큰 차이가 없었다(p<0.05). 이상의 결과로 볼 때, Bacillus amyloliquefaciens CS47와 Saccharomyces cerevisiae로 발효시켜 기호성과 저장성이 개선된 새송이버섯 수확 후 배지는 한우 거세우의 원료사료로 사용 가능한 것으로 사료된다.
