본 연구는 옥수수 수확 시 세절여부에 따라 제조된 옥수수 사일리지를 이용하여 TMR 제조시 배합시간에 따른 물리적 특성(Particle size 및 laceration)과 반추위 내 in situ 건물분해율에 미치는 영향을 조사하고자 수행되었다. TMR 시험사료는 세절(20 mm)한 것(T1구)과 세절하지 않은 옥수수 사일리지(T2구)를 이용하여 총 60분간 배합하면서 시료를 채취한 후 Penn State Particle Separator(PSPS)로 분석하였다. 모든 배합시간에서 T2구보다 T1구에서 상층(>19 mm)과 하층(<8 mm)이 유의적으로 낮았고(p<0.05), 중층(8-19 mm)은 유의적으로 높았으며, 굵은 비율(≥1 mm)의 감소율도 높은 경향을 나타내었다. 그리고 peNDF>8.0 및 반추위 내 in situ 건물분해율도 T1구에서 유의적으로 높게 나타났다(p<0.05). 본 연구 결과에서 옥수수 사일리지 위주의 TMR 제조 시 세절하지 않은 것보다 세절한 옥수수 사일리지가 적정 peNDF 범위가 유지되어 조사료로서 사료적 가치를 증진하는데 효과가 있을 것으로 기대된다.

Eggplant pickles were classified into three groups based on salt concentration (1, 3, 5%) and three groups based on drying time (30, 60 and 120 minutes), followed by storage at 5℃ for 28 days. Raw eggplant contains 94.82% water content. The increase in salt concentration and drying time caused a decrease in the moisture content. Compared to the 0.27% ash content of raw eggplant, the ash content of eggplant pickles increased noticeably with increasing salt concentration due to penetration into the eggplant pickles. pH values decreased significantly as the levels of salt concentration and dying time increased (p〈0.05). In terms of storage time, pH values decreased from 21 days. The variation in salinity increased significantly as the concentration of salt increased. Compared to normal pickles salted at 5.39% salinity, eggplant pickles constituted 0.27~0.77% (1%), 0.40~1.14% (3%), and 0.47~11.20% (5%) 'low-salinity' eggplant pickles. Reducing-sugar content differed on the dates of 7, 14 and 21 in drying time and at 3% salinity. Hardness differed at 30, 60, and 120M on the 28th and 1, 5% salt concentration. Resilience differed according to drying time and from dates of 0 to 14th. The number of total microbes decreased at low salinity. In terms of storage time, the number of microbes tended to decrease after the 21st. In the consumer preference test, lightness of 5%-30M was the highest value.
