The Effect of Pre-Wilting Herbage on the Composition and Feeding Value of Silage

예건의 Silage의 품질에 미치는 영향

Experiment were conducted to study effect of pre-wilting on the quality of silage. Herbage samples were taken on November 11, 1981. Italian ryegrass and rye plant at grazing stage were taken and wilted to adjust their dry matter contents to the range of 15.8 to 53.2% and ensiled in order to evaluate the effect of pre-wilting on the chemical composition and nutrient loss of silage. Both prewilted and unwilted grass material were ensiled in small polyetylene film bag and stored under room temperature. 1. The formation of total acid decreased by increasing DM content, however, lactic acid content of the total organic acid increased. 2. In the silage, the loss of DM declined as DM content increased. 3. The quality of silage estimated by organic acid constituent was improved as DM content in the herbage increased. 4. The production of $NH_3-N$ decreased by increasing degree of prewilting. 5. In vitro dry matter digestibility was not affected by prewilting.

재료(材料)의 예건수준(豫乾水準)에 따른 건물함량(乾物含量)이 사일리지 품질(品質)에 미치는 影響(影響)을 알고져 1981년(年) 11월(月) 11일(日)에 호밀과 이탈리안라이그라스를 수확하였다. 예건(豫乾)에 의하여 재료(材料)의 건물함량(乾物含量)을 15.8%에서 53.2%까지 4수준(水準)으로 조절하였으며 사일리지는 폴리에틸렌필름봉지에 넣어 실온에 저장하였다. 1. 유기산(有機酸)의 함량(含量)은 재료(材料)의 건물함량(乾物含量)이 증가(增加)됨에 따라 감소(減少)하였으나 총산에 대한 유산(乳酸)은 증가(增加)하였다. 2. 건물손실(乾物損失)은 재료(材料)의 건물함량(乾物含量)이 증가(增加)함에 따라 감소(減少)하였다. 3. 사일리지의 품질(品質)은 건물함량(乾物含量)이 증가(增加)함에 따라 양호(良好)하였다. 4. 암모니아태질소는 건물함량(乾物含量)이 증가(增加)함에 따라 감소(減少)했다. 5. Invitro 건물소화율(乾物消化率)에는 건물함량(乾物含量)에 의한 차(差)가 없었다.
