What is the proper moisture content of chopped corn or sorghum forage for silage making?

The proper moisture content of chopped corn or sorghum forage for silage making is crucial for ensuring the fermentation process occurs effectively. The optimal moisture range for these forages is between 65-70%. This higher moisture content facilitates the anaerobic fermentation process that is necessary for silage preservation.

When the moisture content is within this range, it promotes the growth of desirable lactic acid bacteria, which helps in lowering the pH of the silage quickly. This rapid acidification is essential to inhibit the growth of undesirable microorganisms and prevents spoilage. If the moisture content is too low, it can lead to poor fermentation, resulting in dry matter loss and spoilage. Conversely, excess moisture can create a slick environment that can impede proper fermentation and increase the risk of spoilage due to seepage.

In summary, maintaining a moisture content of 65-70% ensures an effective fermentation process, preserving the nutritional quality and palatability of the silage.
