초록

본 연구는 한약재 (결명자, 계피, 산초, 감초) 추출물의 반추위내 발효와 미생물 활성에 대한 효과를 구명하기 위하여 수행되었다. In vitro 건물소화율은 계피와 산초 추출물 첨가구에서는 0시간대, 감초 추출물 첨가구에서는 3시간대에 대조구에 비해 현저히 (P<0.05) 낮았다. 한약재 추출물 첨가에 따른 발효 시간대별 휘발성 지방산 조성의 변화는 3시간대에서만 처리간 유의성이 인정되었는데, acetate 비율은 대조구가 천연 추출물 첨가구보다 유의적으로 높았으나, butyrate, isobutyrate, isovalerate 및 valerate은 대조구에서 가장 낮았다 (P<0.05). 미생물 성장율은 발효 3시간대에서 결명자 첨가구를 제외한 한약재 첨가구에서 대조구에 비해 유의적 (P<0.05)으로 높았으나 다른 발효 시간대에서는 차이가 없었다. 이상의 결과로부터 한약재로 사용되고 있는 계피, 산초 및 감초 추출물을 in vitro 반추위 배양액에 첨가하였을 때, 발효초기에 반추위 미생물의 활성을 억제하는 경향은 있었으나 미생물 성장에 대한 억제 효과는 없는 것으로 나타났다.

This study was conducted to investigate the effect of herbal (Obtusifolia, Cinnamon, Chinese pepper, Licorice) extracts on the rumen fermentation in vitro. Comparing to the control, in vitro dry matter digestibility was significantly (P<0.05) decreased at zero hour in the Cinnamon and the Chinese pepper, and at three hour after supplementation in the Licorice. The ratio of volatile fatty acids were significant (P<0.05) differences at 3 hour after fermentation only, acetic acid was higher (P<0.05) in the control compare to the herbal extract treatments, but the ratios of butyrate, iso-butyrate, iso-valerate and valerate were lowest in the control. The growth rate of rumen microbes in vitro was significantly (P<0.05) higer in the herbal extract treatments excluding the Obtusifolia than the control during three hour fermentation, but was not significant difference among treatments in the other fermentation times. From above results, even though the extracts of Cinnamon, Chinese pepper and Licorice inclined to inhibit the activity of rumen microbes during early fermentation period, but did not affect on the growth rate of rumen microbes in vitro.
