초록

본 연구는 사일리지 발효제 첨가가 볏짚 사일리지에서 곰팡이 독소 및 in situ 섬유소 소화율에 미치는 영향을 평가하고자 실시하였다. 사일리지 발효제로 L. plantarum 단일제 및 L. plantarum과 S. cerevisiae의 혼합제를 첨가하였을 때 사일리지의 발효 및 섬유소 분해에 영향을 주었을 뿐만 아니라 곰팡이독소 감소에도 영향을 주었다. 시험 시료에서 곰팡이독소 중 ochratoxin A 및 zearalenone만 발견되었다. Ochratoxin A 및 zearalenone는 대조구에서 각각 38.11±2.22 및 633.67±50.30 ug/kg 수준으로 발효제 첨가로 감소경향이 나타났고, 혼합제에서만 각각 27.78±2.28 및 392.72±25.04 ug/kg 수준으로 유의적 차이를 보였다(p<0.05). pH는 대조구에 비하여 단일제 및 혼합제에서 낮았고(p<0.05), lactic acid는 대조구(8.18±0.93 mM)에 비하여 단일제(11.73±0.31 mM)가 높았고, 혼합제(16.01±0.88 mM)에서 가장 높은 수준을 나타내었다(p<0.05). Acetic acid와 propionic acid는 발효제 첨가에 따라 유의적으로 낮아짐을 발견하였다(p<0.05). 그리고 total VFA도 발효제 첨가가 대조구에 비하여 낮았다(p<0.05). NDF 및 ADF의 반추위 in situ 분해율은 배양기간 동안 혼합제가 가장 높은 수준의 분해율을 유지하였고, 다음으로 단일제가 높았으며, 대조구가 가장 낮은 수준을 유지하였다. 그리고 이들 NDF 및 ADF 분해율은 각각 배양 12 및 24시간 이후 모든 시간대에서 실험구간 유의 차를 나타내었다(p<0.05). 이상의 연구 결과는 볏짚 사일리지 제조에서 사일리지 발효제사용은 발효 및 섬유소 분해에 영향을 주었을 뿐만 아니라 곰팡이독소 감소에도 영향을 주었다. 그리고 곰팡이독소 감소는 L. plantarum 단일제보다 L. plantarum과 S. cerevisiae 혼합제의 효능이 더 크게 나타났다. 따라서 사일리지 조제를 위한 발효제로 L. plantarum과 L. plantarum 첨가제의 사용은 사일리지의 품질과 안정성을 더 증진할 것으로 사료 된다.

This study was conducted to evaluate the efficacy of adding the microbial inoculants to silage for reducing mycotoxins in rice straw silage. When a single agent of L. plantarum and a mixed agent of L. plantarum and S. cerevisiae were added in rice straw silage contaminated mycotoxins, it had an effect on silage fermentation and fiber degradation as well as mycotoxin reduction. Among the mycotoxins, only ochratoxin A and zearalenone were found in the test sample. Ochratoxin A and zearalenone showed a decreasing trend with the addition of silage inoculants compared to the control groups (38.11±2.22 and 633.67±50.30 ㎍/kg), and there was a significant difference at the mixed agents; 27.78±2.28 and 392.72±25.04 ㎍/kg, respectively (p<0.05). The pH was lower in the single agent and the mixed agent compared to the control (p<0.05). The concentration of lactic acid was higher in the single agent (11.73±0.31 mM) than in the control group (8.18±0.93 mM), and the highest concentration was 16.01±0.88 mM in the mixed agent (p<0.05). Acetic acid and propionic acid were found to be significantly lowered with the addition of silage inoculants (p<0.05). Total VFA was also lower at the addition of silage inoculants than the control group (p<0.05). The rumen in situ dry matter degradation of NDF and ADF was maintained at the highest levels of the mixed agent during the culture period, followed by the single agent and the control group at the lowest level. NDF and ADF degradation showed a significant difference at all time points after 12 and 24 hours of culture, respectively (p<0.05). The study results showed that the silage inoculants had the positive effects on quality increasing of rice straw silage; fermentative charateristics, fiber degradation and mycotoxins reduction. Ochratoxin A and zearalenone were greater reduction by adding bacterial inoculants of silage. Therefore it is considered that L. plantarum and S. cerevisiae will improve the quality and stability with remediation of mycotoxin in silage.
