Silage is a fermented and preserved forage feed made from green crops, primarily grass or other crops like corn or legumes. This process involves harvesting the crop at a high moisture content, chopping it into small pieces, and then ensiling or fermenting it in an airtight environment, usually a silo. The anaerobic fermentation that occurs during ensiling preserves the forage, creating a nutrient-rich feed for livestock, particularly cattle.

The key benefits of silage include its ability to extend the availability of high-quality forage beyond the growing season, ensuring a consistent and nutritious feed for animals throughout the year. Silage is known for its higher energy and nutrient content compared to dry forages, making it a valuable component in the diet of dairy and beef cattle, as well as other ruminants.The silage production process involves careful management of factors such as moisture content, chopping length, compaction, and sealing to create an optimal environment for fermentation.
