A forage harvester – also known as a silage harvester, forager or chopper – is a farm implement that harvests forage plants to make silage. [1] Silage is grass , corn or hay , which has been chopped into small pieces, and compacted together in a storage silo , silage bunker, or in silage bags. [ 2 ]
Forage analysis is necessary and should include dry matter, crude protein, acid detergent fiber, neutral detergent fiber, calcium and phosphorus. TMR can be used effectively by many dairy farmers, but it is not a substitute for good management. In fact, the intensity of management may be increased.
Silage must be firmly packed to minimize the oxygen content, lest it spoil. Silage goes through four major stages in a silo: [14] Presealing, which, after the first few days after filling a silo, enables some respiration and some dry matter (DM) loss, but stops. Fermentation, which occurs over a few weeks.
The production of silage often involves the use of an acid conditioner such as sulfuric acid or formic acid. The process of silage making frequently produces a yellow-brown strongly smelling liquid which is very rich in simple sugars, alcohol, short-chain organic acids and silage conditioner. This liquor is one of the most polluting organic ...

[1] It utilizes the principles of managed grazing, and it is one of several distinct forms of agroforestry. [2]
Once silage has entered the conveyor system, it can be handled by either manual or automatic distribution systems.

When slid open, the forage drops through the open hole and down a chute into a wagon, wheelbarrow, or open pile.
