Formic acid와 Caproic acid 첨가가 Reed Canarygrass Silage의 품질과 호기적 변패에 미치는 영향
Effect of Formic acid and Caproic acids on the Quality and Aerobic Deterioration of Reed Canarygrass Silage
초록
본 시험은 reed canarygrass silage의 품질을 향상시키고 호기적 변패를 방지시킬 목적으로 재료를 약 1.5cm 길이로 절단하여 formic acid, caproic acid 및 두가지 산을 혼합하여 첨가한 silage를 9개의 처리구로 나누어 실험용 silo에 제조하였으며, silage의 품질분석을 위해서 두께 0.1mm, 용량 50kg의 vinyl bag을 이용하였다. 또한 호기적 상태에서의 온도변화, 질소 함량 변화 및 변패방지를 위한 silage의 안정성 시험은 지름 25cm
In order to study the effects of silage additive on the quality and in preventing aerobic deterioration, reed canarygrass silages were made with various levels of formic acid, caproic acid and a mixture of the two acids. Preparation of silages cutted into about 1.5 cm length with the forage cutter and packed in vinyl bags(50 kg of capacity, 0.1 mrn of thickness), and it also divided nine types of experimental treatments. Aerobic deterioration in the silages were investigated for 7 days of aerobic exposure periods, and the plastic vessel of diameter 25 cm, a height 30 cm used as a tool. The results obtained from this experiment are summarized as fellow. 1. Crude protein and NFE contents at the time if opening were increased in the silage with mixture of formic and caproic acids(P<0.01). Crude fiber and ADF contents during the 7 days of aerobic exposure periods were the decreased in the sslages with mixture of two acods treatment(P<0.01). 2. Temperature of the silage treated with fromic acid alone during the 2 days of aerobic exposure period reached
