Abstract

This study was conducted to know the optimal supplementary level of spent mushroom substrates (Flammulina velutipes) as an energy source and fermentation period in manufacturing of rye silage. Whole crop rye was harvested at full bloom stage and ensiled with spent mushroom substrates of 20%(S-20), 40%(S-40) and 60%(S-60) as fresh matter basis. Each silage was prepared in plastic buckets included with vinyl bag by three replications and fermented for 3, 6 and 9 weeks, respectively. Moisture contents of whole crop rye at full bloom stage and spent mushroom substrates were 62.3% and 54.3%, respectively, and those of silages was ranged from 58% to 64%. Ether extracts content of silages was significantly (P<0.05) increased in 6 weeks of fermentation period. The pH of silages ranged from 4.46 to 5.05, and fluctuated in the changes by fermentation period beside of decreased with elapsing the period in the S-60. The organic acid content of silages was higher in the order of lactic acid, butyric acid, acetic acid and propionic acid. Lactic acid content was higher when fermented for 6 weeks compared to the other fermentation period. Flieg's score for estimation of silage quality ranged from 63 to 80, and was relatively high level in the S-20 and the S-40 fermented for 6 weeks, and was high level in S-20, and was relatively low level in the silages fermented for 3 week. Hence, we suggest that supplementation of 20% spent mushroom substrates in fresh matter basis and fermentation for 6 weeks are resonable for a good quality of rye silage.

본 연구에서는 팽이버섯 수확후배지의 이용성 향상을 위하여 결실기 호밀 사일리지 제조시 에너지 공급원으로서 팽이버섯 수확후배지의 적정 첨가비율과 발효기간을 조사하였다. 원물기준으로 20%(S-20), 40%(S-40), 60%(S-60)의 팽이버섯 수확후배지와 결실기 호밀을 비닐이 내장된 플라스틱 통에 진압 충진한 후 밀봉한 다음 3, 6, 9주 동안 발효시켜 사일리지를 제조하였다. 사일리지 원료로서 결실기 호밀과 팽이버섯 수확후 배지의 수분 함량은 각각 62.3%와 54.3%였으며 호밀사일리지의 수분함량은 약 58-64% 범위였다. 팽이버섯 수확후배지가 첨가된 사일리지의 성분 함량은 처리구별로 유의차가 없었으나 조지방 함량은 6주 동안 발효시킨 처리구에서 유의적으로 증가하였다(P<0.05). 사일리지의 pH는 4.46-5.05수준으로서 S-60구는 발효기간이 경과함에 따라 낮아졌으나 타 처리구에서는 발효기간에 따른 변화가 일정하지 않았다. 사일리지의 유기산 함량은 유산, 낙산, 초산, 프로피온산 순이었으며 유산은 6주 동안 발효시킨 처리구가 타 처리구에 비해 높았다. 사일리지 품질평가 기준인 Flieg's score는 63-80점 수준으로 6주 동안 발효시킨 S-20과 S-40구에서 가장 높았으며 버섯수확후배지 첨가수준별로는 S-20구가 높았고 발효기간별로는 3주 동안 발효시킨 구에서 낮은 편이었다. 이상의 결과들을 종합해 볼 때 에너지원으로서 팽이버섯 수확후배지를 첨가한 결실기 호밀 사일리지는 버섯수확후배지를 원물기준으로 20% 첨가하여 6주 동안 발효시킨 처리구의 사일리지 품질이 가장 우수하였다.
