Loss of leaves in handling decreases feed value. Leaf losses are likely to occur when legumes are cut and raked for hay, but can be minimized by harvesting with a mower conditioner. Rapid dry-down of Hay Large losses in feeding value may result when hay is exposed to weather. Rapid-curing, collection and proper storage of forage reduces these losses. The following table summarizes the types and magnitude of losses that may be expected under good management and harvesting conditions.
Much higher losses are possible with all systems under fair or poor conditions.
These figures are valid only if proper care and management are provided to all harvesting and storage operations. Forage dry matter content can be easily determined in a few minutes, using a microwave oven and a small fish or diet scale. Dry matter losses of hay and silage during harvesting and storage. Benefits include being able to use existing round-bale equipment, and lower field and feeding losses than with dry hay. Because stands with a high sugar content ensile well, best results are usually found with mixed alfalfa-grass stands cut at an early growth stage.
