Corn Silage as known as king of silages, is one of the best silage for ruminant animals because it contains high total digestible nutrients. Corn is rich in nutrients and flora. When silage process will generates lots of lactic acid to lower the silage PH. However, due to contact with air after opening, the spoilage bacteria such as yeast, mold, and clostridium are actively growing. Which is easy to cause secondary fermentation and heat up the forage or mold will damage the original nutrition value. SYNFERM Corn Silage can effectively inhibit the growth of yeast and mold and delay the time of secondary fermentation. The stability of the forage after opening is increased, which can help farmers produce good quality silage, suitable for forage of 25-35% of dry matter.
