이 연구는 사료맥류의 기계화 수확작업 시 발생하는 식물체 의 예취 높낮이가 조사료 생산성 및 품질에 어떠한 영향을 주 는지를 검토하기 위하여 수확적기에 도달한 청보리, 귀리, 트 리티케일, 총체밀를 각각 5 cm, 10 cm 및 20 cm 높이로 예취 하여 예취높이에 따른 조사료 수량, 사료가치 및 경제성을 분 석하였다. 생초와 건물수량 및 TDN 수량은 20 cm에 비해 5cm와 10cm로 예취하였을 때 현저하게 높게 나타났으며 (P<0.05), 조단백질, NDF, ADF 함량과 DMD은 예취높이의 영향을 받지 않았다. 상대적 사료가치(RFV)는 영양보리와 유 연보리가 예취높이에 상관없이 비슷한 값을 나타냈고, 귀리는 예취높이가 20 cm일 때 가장 높은 값을 나타냈는데 반해 (P<0.05), 트리티케일과 밀은 예취높이가 20 cm일 때 가장 낮 은 값을 나타냈다(P<0.05). 예취 높이에 따른 손익을 분석한 결과 사료맥류의 예취 높이를 5~10 cm 수준으로 유지하면 20 cm로 하였을 때보다 7~25%까지 소득증가 효과를 얻을 수 있었다.


This study was carried out to examine the effect of cutting height on the forage yield and quality. Winter forage crops, including barley, oat, triticale and wheat, were cut at 5, 10 and 20cm from the ground, and their forage yield, feed value and economic value were evaluated. Fresh yield, dry matter yield and TDN yield of the forage crops at 5 cm and 10 cm cutting height were significantly higher than those at 20 cm cutting height. However, crude protein, NDF, ADF and DMD of the forage crops were not shown to be affected by the different cutting height. Relative feed value (RFV) of barely (Youngyang and Yuyeon) was similar regardless of their cutting height. At the level of 20 cm cutting height, RFV was the highest in oat, but the lowest in both wheat (Kumkang) and triticale. From the result of economic value evaluation, it was shown that farm income can be increased from 7 to 25 % by the forage crops as their cutting height were 5 to 10cm compared to 20cm cutting height.
