Remove corn husks packed in bags. 50x87 cm Using suction out the air To achieve a state of fermentation in anaerobic conditions. Tie the gag bag firmly take the time to ferment corn 34 days to evaluate the quality silage by sampling for analysis and evaluation by the senses, the moisture content before fermentation and after fermentation, pH - alkalinity (pH). , organic acids (acetic, butyric and lactic acid) by means of distillation. And analyzing dry matter, protein, fat, ash and organic matter by means proximate. And fiber analysis by detergentmethod By weighing approximately 200 grams of sample fresh baked at a temperature of 60 ° C for 36 hours to measure the pH - pH glass electrode pH meter to measure the amount of organic acids (acetic, butyric and lacticacid) by distillation
