Abstract

In this study, changes of ammonia, alcohol and volatile fatty acid(VFA) concentrations or pH in in vitro ruminal fluid were studied to determine the effects of alcoholic feeds on in vitro ruminal fermentation characteristics. To formulate the alcoholic feeds, alcohol was added to commercial formulated feed at the levels of 1, 3, and 5 %. Experiments were done with four treatment groups, control(commercial feed), AF-1(commercial feed+1% alcohol), AF-3(commercial feed+3% alcohol), and AF-5(commercial feed+5% alcohol). Ammonia concentrations of AF-1 and AF-5 were significantly lower than that of control for the 12h incubation(p<0.05). Ruminal alcohol concentration was increased with the addition level of alcohol increased(p<0.05). TVFA concentrations of AF-1, AF-3 and AF-5 were significantly higher than those of control at 12h(p<0.05). Significant decrease of molar percentage of acetate was observed in control from 8 to 12h incubation, but molar percentage of acetate for AF-1, AF-3 and AF-5 was constant. Molar percentage of propionate was increased in control compared with AF-1, AF-3 and AF-5 from 8 to 12h incubation(p<0.05). Molar percentages of butyrate and valerate were higher in AF-1, AF-3 and AF-5 than in control(p<0.05). Molar percentage of caproate for AF-1, AF-3 and AF-5 was 0.05, 0.58 and 0.47M% at 8h, respectively, but that was not detected for control. Present results may indicate that the alcoholic feeds show positive effects on in vitro ruminal ammonia, alcohol and VFA concentrations or pH. Furthermore, the results of this study implies that the addition level of 5% could be more effective to ruminal fermentation than other addition levels.

본 실험은 alcohol 사료 처리에 따른 in vitro 발효 pattern의 변화를 검토하여 alcohol 사료 처리가 반추위내 발효 pattern에 미치는 영향을 규명코자 실시하였다. 시험구 처리는 배합사료를 첨가하는 대조구(control), 배합사료와 1, 3 및 5%의 alcohol 사료(Alcoholic feed; AF)를 첨가하는 처리구를 각각 AF-1구, AF-3구 및 AF-5구로 나누어 실시하였다. 배양 12시간 동안 ammonia 농도는 AF-1, AF-5구에서 대조구에 비해 낮았다(p<0.05). 배양액의 alcohol 농도는 alcohol 첨가 수준이 증가할수록 높았다(p<0.05). 배양 12시간에 TVFA 농도는 AF-1, AF-3 및 AF-5에서 대조구에 비해 현저히 높았다(p<0.05). 배양 8～12시간 사이에 acetate 비율은 대조구에서 빠른 속도로 감소하였으며, AF-1, AF-3 및 AF-5구에서는 일정한 수준을 유지하는 것으로 나타났다. Propionate 비율은 배양 8～12시간 사이에 AF-1, AF-3 및 AF-5에 비해 대조구에서 빠른 속도로 증가하였다(p<0.05). Butyrate 및 valerate 비율은 AF-1, AF-3 및 AF-5에서 대조구에 비해 높았다(p<0.05). Caproate 비율은 배양 8시간에 AF-1구, AF-3구 및 AF-5구에서 각각 0.05, 0.58 및 0.47M%로 나타났으나, 대조구에서는 검출되지 않았다. 본 실험의 결과에서 alcohol 사료의 처리는 in vitro 반추위액의 ammonia, alcohol 및 휘발성지방산 농도와 pH에 긍정적인 영향을 미치는 것으로 판단된다. 또한 본 실험의 결과에서는 5%의 alcohol 첨가 수준이 여타 alcohol 첨가 수준에 비해 반추위 발효에 보다 효과적인 것으로 사료된다.
