Fermented forage refers to plant materials, such as grasses and legumes, that have undergone a fermentation process. This process typically involves the anaerobic breakdown of sugars by beneficial bacteria, resulting in preserved feed that is rich in nutrients. Fermented forage is commonly used in livestock diets to enhance digestion and improve overall health. The fermentation process helps to increase the availability of nutrients and can reduce the risk of spoilage. Common types of fermented forage include silage, made from chopped green plants, and haylage, which is similar but contains higher moisture content. Both are valuable for feeding cattle and other ruminants.
