บทคัดย่อ (EN): This study evaluated the physical quality and organic acid composition of grass silages prepared with and without effective microorganism (EM) and cassava starch at the time of ensiling. The native grasses in central region of Lao PDR were cut into pieces as long as pieces 2-3 cm and randomly allocated in a randomized complete block design with six treatments: T1= 10 ml EM + 0 g starch, T2= 7.5 ml EM + 2.5 g starch, T3= 5 ml EM + 5 g starch, T4= 2.5 ml EM + 7.5 g starch, T5 = 0 ml EM + 10 g starch, T6 = silage without additive (control). Three of which were sampled on days 0 and 30 after ensiling. The color of silage was measured by the CIE L*a*b* system using Hunter Labmini scan EZ. The results showed that the silage treated with 10 g of starch had a lowest pH (pH = 3.82). Silage with 2.5 ml of EM with 7.5 g starch had higher greenness more than control. Organic acids and short chain fatty acids of silage such as succinic acid, formic acid, acetic acid, propionic acid and butyric acid at 0 day of ensiling were not significantly different. However, the highest level of lactic acid at 30 days of ensiling was Hymenachne sp. grass silage treated with 5 ml EM + 5 g starch (T3). In conclusion, effective microorganism and starch used in this study improved color characteristics, reduced pH content of silage and increased lactic acid concentration of grass silage.
