Evaluation of Fermentation Ability of Microbes for Whole Crop Rice Silage Inoculant

총체 벼 사일리지용 미생물의 발효능력 평가

  • Published : 2008.09.30

Abstract

This experiment was conducted to study on the evaluation of fermentation ability of microbes for whole crop rice silage Inoculant at National Institute of Animal Science, RDA from 2004 to 2005. We collected 28 strains of microbes from whole crop rice silage. According to acidity and growth ability, 5 strains of microbes was isolated (R4-1, R7-1, R7-2, R10-1, R12-1). The cultures of 4 strains were identified to be Lactobacillus plantarum (R4-1, R7-1, R7-2 and R10-1) and one was identified to be Lactobacillus pentosus (R12-1). Whole crop rice was harvested at the yellow ripen stage. It was ensiled in experimental silos (20ℓ capacity) with or without microbial additives (R4-1, R7-1, R7-2, R10-1, R12-1 and three commercial inoculant) and stored at room temperature for 60d. The pH value and acetic acid content of additivetreated silages were lower and lactic acid content was higher than those of the control (p<0.05). There was a trend for acetic acid content to be lowest and lactic acid to be highest in R7-1 treated silage. Crude protein (CP) contents of R7-2 treated silage was higher and acid detergent fiber (ADF) and neutral detergent fiber (NDF) contents of R7-1 treated silage was lower (p<0.05). Although some strains of inoculant could improve silage quality, L. plantarum R7-1 was more effective as an inoculant for whole crop rice silage. This microbe was named NLRI 401 and registered in the Korea Agricultural Culture Collection.
