Säilörehä

Säilörehä is a Finnish term referring to silage wrap, a plastic film used in agriculture to create silage. Silage is a method of preserving forage by fermentation, typically of grass or legumes, in an anaerobic (oxygen-free) environment. The process is crucial for livestock farming as it allows farmers to store feed for use during periods when fresh forage is unavailable, such as during winter months or droughts.

The säilörehä is a key component in the ensiling process. After forage is harvested and chopped, it is tightly packed into a silo or, more commonly today, baled. The bales are then individually wrapped with multiple layers of the specialized plastic film. This wrapping creates an airtight seal, which is essential for the anaerobic fermentation to occur. The plastic protects the forage from external contaminants like dirt, rain, and excessive oxygen, which could lead to spoilage or mold growth.

The säilörehä is typically made of polyethylene, a durable and flexible plastic designed to withstand outdoor conditions and the stresses of handling. It often contains additives to protect it from UV radiation, ensuring its integrity over extended storage periods. The color of the wrap can vary, with white and green being common. The process of wrapping bales with säilörehä is usually done by specialized machinery, making it an efficient method for feed preservation on modern farms. The quality of the wrap and the effectiveness of the sealing process directly influence the nutritional value and palatability of the resulting silage.
