Abstract

This study was conducted to investigate the effects of fermented spent mushroom substrates (F-SMS) of Flammulina velutipes on growth performance, carcass traits, and economic characteristics of Hanwoo steers. A yeast strain (Saccharomyces sp. UJ14) and Bacillus strain (Bacillus sp. UJ03) isolated from fresh spent mushroom substrates of Flammulina velutipes were used as probiotics to prepare F-SMS. Twenty-four Hanwoo steers (14 months old) were allocated to three dietary treatments via a randomized block design and were slaughtered at 30 months of age. These treatment groups included Control (TMR), T1 (TMR containing 10% of F-SMS) group, and T2 (TMR containing 30% of F-SMS). Body weight gain was not influenced by the experimental diets. DM and TDN intakes in the finishing period were significantly (p < 0.05) greater in group T1 than in other groups. CP intake was significantly (p < 0.05) greater in group T2 than in other groups during the whole experimental period. Among carcass traits, rib-eye area and back fat thickness tended to increase with F-SMS supplementation. The appearance rate (%) of a meat yield more than grade A was the highest in group T1. The net profits increased by 1.2% and 13.3% in groups T1 and T2, respectively. In conclusion, if a proper feeding program (including feed safety) can be ensured, spent mushroom substrates of Flammulina velutipes can prove to be a highly profitable feed source for Hanwoo steers.

본 연구는 팽이버섯 수확후배지를 이용한 발효 TMR 급여가 한우 거세우의 사양성적과 도체특성 및 경제성 분석에 미치는 영향을 조사하기 위해 수행되었다. 팽이버섯 수확후배지 발효사료(F-SMS) 제조를 위하여 자체 개발된 혼합배양액(Bacillus sp. UJ03+Saccharomyces sp. UJ14)을 사용하였다. 한우 거세우 14개월령 24두를 공시하여 성장단계(비육전기, 비육후기, 비육마무리기)에 따라 배합비를 조절하면서 사육한 후, 30개월령에 도축하였다. 처리구는 자체 TMR을 급여한 대조구(Control), F-SMS 10% 첨가구(T1) 및 30% 첨가구(T2)로 나누어 난괴법으로 배치하였다. 증체량은 처리구간에 유의적인 차이가 없었으나. 건물과 TDN 섭취량은 비육 마무리기에 T1구에서 다른 처리구보다 높았고, 조단백질 섭취량은 전 시험 기간 동안 T2구가 다른 처리구에 비해 많았다(p<0.05). 배 최장근 단면적과 등지방두께는 팽이버섯 수확후배지 발효 사료 급여 시 증가되는 경향이었으며, T1구에서 육량 A등급 출현율이 가장 높았다. 순수익은 대조구에 비해 T1과 T2구가 각각 1.2% 및 13.3%가 증가한 것으로 나타났다. 이상의 결과들을 종합해 볼 때, 팽이버섯 수확후배지의 원료비와 발효사료 제조비용의 변동이 없고, 사료로서 안전성이 확보된다면, 팽이버섯 수확후배지는 한우 비육에 있어서 우수한 대체사료자원으로서 농가소득에 크게 기여할 것으로 판단된다.
