摘要:This study aimed to investigate the effect of moisture content in sweet corn waste and fermentation period on silage quality. Three pressure levels of 0, 0.6675 and 1.0013 N/cm2 (Newton per square centimeter) for 1 minute were assigned to sweet corn waste obtained from the sweet corn factory. Four fermentation periods at 0, 30, 60 and 90 days were assigned on silage for the 3 x 4 factorial experimental design. The result showed that level of pressure yielded different values (p < 0.01), for the dry matter, moisture, crude fiber, NFE, NDF, ADF, ADL, gross energy, lactic acid, acetic acid and the butyric acid, except crude protein, fat, ash and pH content. It was found that dry matter, crude fiber, NDF, ADF and gross energy increased when the level of pressure increased. The period of fermentation had significant effect (p < 0.01) on chemical composition. The pH levels were high at 30 day fermentation and decreased at longer period up to 90 days. We concluded that sweet corn waste silage with higher dry matter content and being fermented for 30 days contained the highest nutritive values among all treatment combinations.
