Preserve Fodder is a process of storing animal feed for long-term use. The term is derived from the French word ensile, which means to store in a silo. This process involves packing the fodder into a silo or other airtight container, where it can be kept for up to several years without spoiling. The fodder is usually made up of grains, hay, and other plant materials, which are then treated with preservatives to prevent spoilage. This process helps to ensure that livestock have access to food during times of drought or other shortages.
