When working with two or three groups it is easier as the caretaker can feed the low costing forage to the low group and the high quality forage to the higher group to increase the overall health and performance of the cows. For dry cows this system can minimize metabolic and nutritional disorders in calving and the post-partpartum period.
Forage harvesters can be implements attached to a tractor, [4] or they can be self-propelled units. In either configuration, they comprise a drum (cutterhead) or a flywheel [5] with a number of knives fixed to it that chops and blows the silage out of a chute of the harvester into a wagon that is either connected to the harvester or to another vehicle driving alongside.

[1] It utilizes the principles of managed grazing, and it is one of several distinct forms of agroforestry. [2]
The favourable results obtained in the US led to the introduction of the system in the United Kingdom, where Thomas Kirby first introduced the process for British dairy herds. [6] The modern silage preserved with acid and by preventing contact with air was invented by Finnish academic and professor of chemistry Artturi Ilmari Virtanen. Virtanen ...
Once silage has entered the conveyor system, it can be handled by either manual or automatic distribution systems. The simplest manual distribution system uses a sliding metal platform under the pickup channel. When slid open, the forage drops through the open hole and down a chute into a wagon, wheelbarrow, or open pile.
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 ...

Historically, the term forage has meant only plants eaten by the animals directly as pasture, crop residue, or immature cereal crops, but it is also used more loosely to include similar plants cut for fodder and carried to the animals, especially as hay or silage.
