The entire corn plant at 60 days interval, typically harvested at a whole plant moisture content of 65%. Up to 50% of the dry matter of corn silage is grain corn. Was collected and chopped into 2-3 cm. Lengths and mixed with different level of pineapple waste. The chopped corn plants was directly packed in airtight plastic bags 0,15-0,17 mm in thickness ). The net weight of a PE bag is 20 KG. Our products without additive gave good preserved corn silage(ph
