초록

본 연구는 국내에서 많이 재배되고 있는 청보리 품종을 논토양에 재배한 후, 생육특성, 화학적 특성, 무기물함량 및 영양수량을 검토하여 사료적 가치를 파악하고 이용에 유리한 품종을 선발하기 위하여 실시하였다. 실험설계는 5품종(유연, 영양, 우호, 다미, 소만)을 3반복으로 하여 2009년 10월 21일 파종하고 이듬해 5월 21일 전 품종이 유숙기에 도달하였을 때 수확하였다. 건물수량은 영양과 다미가 높게 나타난 반면 유연이 낮은 생산량을 나타냈다(p<0.05). 일반성분에 있어서 조단백질, 조지방, 조회분, ADF 및 TDN 함량은 품종들 간 유의적 차이가 나타나지 않았다. 그러나 조섬유 함량은 다미(36.0%)가 가장 높게, 영양 (31.4%)이 가장 낮게 나타났으며(p<0.05), NDF 함량은 우호 > 다미 > 소만 > 유연 > 영양 순으로 높게 나타났다(p<0.05). 총 무기물 함량은 영양 > 우호 > 다미 > 소만 > 유연 순으로 높게 나타났다(p<0.05). 그리고 총 아미노산 함량은 우호 > 영양 > 소만 > 유연 > 다미 순으로 높게 나타나는 경향이 있었으나 유의적이 차이는 없었다. 영양수량에 있어서 조단백질 생산량은 우호가 가장 높게(p<0.05), 무기물, 구성아미노산, 유리당 및 TDN 수량은 영양이 가장 높게 나타났다(p<0.05). 이상의 결과를 종합해 볼 때 영양과 우호 품종이 생산성 및 사료가치가 우수한 것으로 나타났다.

This study was carried out to investigate the growth characteristics, yield, chemical compositions and nutritive yield of whole crop barley varieties harvested in a paddy field. The experimental design was arranged in a randomized block design with three replications. The treatments consisted of five whole crop barley varieties (Yuyeon, Youngyang, Wooho, Dami, Soman). The planting date was on 21 October 2009 and the samples were harvested on 21 May 2010. Dry matter yield was higher in Youngyang and Dami than other varieties (p<0.05). Crude protein, crude fat, crude ash, ADF and TDN were not significantly different. Crude fiber was the highest at Dami (31.4%), and Youngyang (31.4%) exhibited the lowest crude fiber compared to other varieties (p<0.05). NDF was higher in the order of Wooho > Dami > Soman > Yuyeon > Youngyang (p<0.05). Total mineral content was higher in the order of Youngyang > Wooho > Dami > Soman > Yuyeon (p<0.05). The contents of both essential and non-essential amino acids were not different among whole crop barley varieties. Yields of crude protein was the highest in Wooho (p<0.05), and yields of mineral, amino acid, free sugar and TDN were the highest in Youngyang. Based on the results from this study, it can be suggested that Youngyang and Wooho showed to have higher productivity and high nutritive values compared to other varieties.
