Damage caused by weathering of hay is high on many farms, especially in the eastern U.S. It appears that many livestock producers don’t recognize the magnitude of such losses or how much they costs. In many cases, it would cost relatively little to reduce or even virtually eliminate weathering damage. Once dry hay is stored in a barn, or othersise well protected from the elements (even just covered well and placed on something such as old tires, shipping pallets or railroad ties), feeding value decreases little over time.
