- W845634947 abstract "우리나라에서는 봄철에 일년생 콩과목초를 수확한 후 포장건조시 목초의 품질에 관한 연구는 거의 없는 실정이다. 따라서 본 시험은 일년생 콩과목초인 crimson clover(Trifolium incarnatum L.), bolta balansa clover(Trifolium balanansae L.) 및 persian clover(Trifolium resupinatum L.)를 봄에 건조하였을 때 건초의 품질에 관한 정보를 얻기 위하여 수행하였다. 일년생 콩과목초의 수확시 건물률은 crimson slover가 24.7%로 가장 높았고, bolta balansa 및 persian clover는 각각 20.4 및 18.8%였다. 콩과목초의 포장 건조후 수분 함량은 persian clover가 가장 낮았으며, 수분함량 20%도달시간은 공시초종 모두 4일이 소요되었다. 반전횟수는 건초의 수분 함량에 영향을 미치지 않았으며, 포장건조 기간중 변화 양상은 비슷하였다. Persian clover의 건물당 잎과 줄기의 비는 crimson 및 bolta balansa clover보다 높았다. 조단백질 함량도 잎이 많은 persian clover가 19.5%로 다른 초종보다 높았다. 포장 건조중 반전횟수를 증가함에 따라 조단백질 함량은 17.8%에서 16.5%로 감소하였다. Persian clover의 NDF 및 ADF함량은 다른 일년생 콩과목초보다 낮았다. 반전횟수에 따른 비교에서는 3회 반전의 NDF 및 ADF 함량이 1회 및 2회 반전보다 높았다. Persian clover의 상대사료가치(RFV)는 178로 가장 높았으며, 이는 건초품질등급의 최상급에 해당된다. Crimson 및 bolta balansa clover의 RFV도 1등급으로 고품질의 건초였다. 반전횟수에 의한 상대사료가치는 반전횟수를 증가함에 따라 150에서 140으로 감소하였다. 이상의 연구결과를 볼 때 persian clover가 식물체 부위중 잎이 많고, 줄기가 비워있고 다른 초종보다 숙기가 늦어, 일년생 콩과목초 중에서 건초 품질이 우수하였다. 그리고 포장건조시 품질손실이 적은 콩과목초를 생산하기 위해서는 반전횟수를 2회이하로 하여야 한다. No comprebensive forage quality of annual legumes harvested and cured in spring has been conducted in Korea. Therefore, this experiment was carried out to gain information on the quality of crimson clover (Trifolium incarnatum L.), bolta baIansa clover(Trifolium ba/anansae L.), and persian c1over(Trifolium resupinatum L.) during field curing in spring. The dry matter content of crimson clover at harvest was 24.7%, while bolta balansa and persian clovers had 20.4 and 18.8%, respectively. The moisture content of persian clover was low at the final curing day. But All species took 4 days to reach moisture content under 20%Tedding frequency did not affect moisture content, but consisten trends were also observed during the field curing. Persian clover tended to show a higher leaf-stem ratio than crimson and bolta balansa clovers on dry matter basis. Crude protein of persian clover(19.5%) was higher than other legumes. The percentage of erode protein was decreased from 17.8 to 16.5% as tedding frequency often did. Neutral detergent fiber(NDF) and acid detergent fiber(ADF) contents of persian clover were lower than those of other legumes. From the comparison among tedding frequency, NDF and ADF contents of three times were higher than those of one and two times. Relative feed value(RFV) of persian clover hay was the highest(178) and classified as Grade Prime in forage quality standard. Crimson and bolta balansa clovers in the RFV were also high quality as Grade 1 in forage quality standard. The RFV of legume hay was decreased from 150 to 140 as tedding frequency often did Results of the experiment indicate that hay quality of persian clover was higher than other clovers. And this is due to high leaf and stem content, hollow stem and late maturity stage. Then tedding frequency in annual legume can be teded by two times for quality." @default.
