Silage is a type of animal feed made from fermented green foliage, typically harvested from crops like corn or grass. The process involves chopping the plants and storing them in a sealed environment, which allows natural fermentation to occur. This fermentation preserves the nutrients and makes the feed more digestible for livestock. Farmers often use silage to provide a nutritious food source during the winter months when fresh forage is scarce. The fermentation process not only helps in preserving the feed but also enhances its flavor, making it more appealing to animals like cows and sheep.
