Abstract

This study was conducted to investigate the feed value and silage quality according to storage period and film layers in whole crop oat silage. The crude protein content was increased in all silage during the storage periods compared to those before silage, under prolonged storage period slightly and the number of film layers of silage, six layer were higher than four layers, but no significant. NDF and ADF contents were also increased in all silage of storage duration compared to those before silage, but they was similar level between storage duration and number of film layers. TDN content was decreased of the storage duration. However, it was similar under the storage duration and the number of film layers. The pH value was decreased during prolonged storage period and six layers was lower than four layers depending on the film layers. In the organic acid contents, lactic acid and acetic acid were increased under the prolonged storage duration, and butyric acid was higher significantly(p<0.05), six layers of the film were showed higher lactic acid and lower butyric acid(p<0.05). Therefore, oat silage should be used within 6 months it was when treated with 4 layers, if considering the long-term storage, it is desirable to treat it with 6 layers or more.

이 연구는 저장기간 및 비닐겹수에 따른 귀리 사일리지의 사료가치 및 사일리지 품질특성을 구명하고자 수행하였다. 귀리 사일리지의 조단백질 함량은 저장기간 모두 사일리지 제조 전에 비해 높아지는 경향을 보였고, 저장기간이 길어질수록 높은 값을 보였지만 통계적인 유의성은 없었다. 비닐겹수에 따라서는 6겹 처리한 처리구가 4겹보다 높은 경향이었다. NDF와 ADF 함량 역시 저장기간 모두 사일리지 제조 전보다 높은 경향을 보였고, 저장기간 및 비닐겹수에 따라서는 비슷하였다. TDN 함량은 저장기간 모두 사일리지 제조 전보다 낮은 경향이었고, 저장기간 및 비닐겹수에 따라서는 비슷한 값을 보였다. pH는 저장기간이 길어짐에 따라 낮아지는 경향을 보였고, 비닐겹수에 따라서는 6겹에서 낮은 값을 보였다. 유기산 함량에서는 저장기간이 길어짐에 따라 젖산함량과 초산함량은 약간 증가하는 경향을 보였고, 낙산함량은 유의적으로 증가하는 경향이었다(p<0.05). 비닐겹수에 따라서는 6겹에서 4겹보다 높은 젖산함량과 낮은 낙산함량을 보였다(p<0.05). 따라서 귀리 사일리지는 4겹으로 처리했을 경우에는 6개월 안에 사용하고, 장기저장을 고려한다면 6겹이상으로 처리하는 것이 바람직하다고 판단된다.
