초록

본 연구는 전남 신안군 비금도 간척 논에서 백수현상이 나타난 벼를 조사료 자원으로 활용하기 위해 백수 벼 사일리지의 사료가치 및 유기산 등 품질을 조사하기 위해서 수행하였다. 벼 백수현상이 가장 심한지역의 총체 벼의 수량은 정상지역보다 약 800 kg/ha 정도 감소되었다. 그리고 벼 백수현상이 가장 심한지역에서의 총체 벼의 조단백질 함량 및 TDN 함량은 벼 백수현상이 없는 정상생육 지역 보다 약간 높은 함량을 보였으나 ADF 및 NDF 함량은 현저하게 감소되었다 (p<0.05). 벼 백수현상이 가장 심한지역과 정상지역의 총체 벼 사일리지 pH는 4.0~5.0을 나타냈으며 젖산균 접종에 의해 pH가 저하되었다. 벼 백수지역과 정상생육 지역 모두 젖산균 접종에 의해 젖산함량은 증가하였으며 초산과 낙산함량은 감소되었다(p<0.05). Flieg법에 의한 총체 벼 사일리지의 품질등급은 젖산균을 접종함으로써 2~3단계 상승되었다. 따라서 본 연구의 결과에서 나타난 바와 같이 백수현상이 나타난 벼도 조사료원으로 활용될 수 있다.

This study was performed to investigate the nutritive values of white panicled rice (Oryza sativa L., WPR) silage manufactured with WPR grown in reclaimed paddy field of Bigumdo of Korea in 2011. The WPR used in this study were collected in 1,000 ha of reclaimed paddy field of Bigumdo and was harvested at dough stage and ensiled. The yield of whole crop rice (WCR) grown in region received the most severe damage (MSD) was lower as about 800 kg/ha as than that in region of normal growth (NG). The content of crude protein and total digestible nutrient in WCR of MSD slightly increased, as compared to that in WCR of NG, but the contents of acid detergent fiber and neutral detergent fiber significantly decreased (p<0.05). The pH in WCR silage of MSD and NG ranged from 4.5 to 5.0 and pH decreased by the inoculation of lactic bacteria (p<0.05). The content of lactic acid in WCR silage of MSD and NG increased by the inoculation of lactic bacteria (p<0.05), but the content of acetic acid and butyric acid decreased (p<0.05). Flieg's score in WCR silage of MSD and NG inoculated lactic bacteria increased from 2 to 3 grade, as comparing to non-inoculation of lactic bacteria. Therefore, this study suggests that WPR can be utilized as forage.
