Abstract

This field evaluated the effect of different yields on the drying rate of Italian ryegrass ("Kowinearly", Lolium multiflorum Lam.) hay during the spring season. The experiment was performed at Hwaseong, 2015. The different yields of the plot were selected by growth and development check. Three treatments were 35 t/ha(Y1), 45 t/ha(Y2), and 60 t/ha(Y3). After harvest with conditioner, it was conducted tedding 1/day. It was investigated patterns for changes in moisture content. The changes in moisture content were respectively Y1 from 78.9% to 14.4%, Y2 from 79.1% to 18.3%, and Y3 from 77.9% to 25.5% for 5days. It was no different significantly for changes in moisture content by yields from 1st day ~ 2nd day, But It was different significantly from 3rd day to 5th day. the content of neural detergent fiber(NDF) and acid detergent fiber(ADF) were respectively about 34%, 59%, regardless of yields (P>0.05). Crude protein of Yields Y1, Y2, and Y3 were respectively 6.9%, 8.7%, and 9.4% (P<0.05). The result of this study that the higher yields, the slower it dried. The Quantity is a factor to effect on drying rate.

본 연구는 국내에서 연구되고 있는 건초 생산연구를 기반으로 이탈리안 라이그라스의 수확량 차이에 따라 건초 생산 소요시간에 대한 효과를 구명하기 위해 이탈리안 라이그라스 "코윈어리"를 공시초종으로 출수 후기에 맞추어 화성의 농가 시험 포장에서 수행되었다. 수확 시 농가 경작 논의 수량을 조사하여 차이가 있는 처리구 Y1=35 t/ha, Y2=45 t/ha, Y3=60 t/ha 선정하였는데 수량에 따라 Swath 두께가 달랐다. 수확부터 둘째 날까지 흐렸고, 둘째날 새벽의 1.3 ml의 강우로 인해 초기 약 2일은 세 처리구간 유의성이 나타나지 않았지만, 이후 3일간, Y1 52.4%에서 14.4%로, Y2 57.0%에서 18.3%로, Y3 60.8%에서 25.5%로 떨어지면서 처리구간 유의적 차이를 보여 수량 차이는 건초 생산 시 건조 효율에 영향을 주는 것으로 나타났다. 건초의 사료가치는 세 처리구 모두 수량차이에 따른 건초의 사료가치는 세 처리구 모두 ADF는 약 34%, NDF는 약 59%로 차이가 없었고 CP의 함량은 수량 차이에 따라 Y1, Y2, Y3에서 각각 6.9%, 8.7%, 9.4%로 나타났다. 양질의 건초 생산 시 수량은 건조 속도를 촉진 또는 지연시키는 주요 요인으로 판단된다.
