In a broad sense, a "forage" is any part of a plant that can be consumed by a grazing animal or that can be harvested for feeding. In general, however, the term "forage" refers to any pasture, hay, silage, or green-chop crop. Forages can be permanently established crops like pastures or hayfields (e.g., tall fescue, bermudagrass, bahiagrass, alfalfa, etc.) and annual crops (e.g, corn for silage, annual ryegrass, etc.).
A forage system is any assembly cool and warm season forage crops that can meet the needs of the animal or livestock enterprise. Usually, forage-based livestock production depends on multiple forage crops within the system so that forage production continues throughout the growing season. Cattle, goats, sheep, horses, and other similar livestock come by forage utilization naturally. Their digestive system allows the animals to derive energy, protein, and other nutrients from fibrous feed sources.
Typically, the most cost-effective way for these animals to consume their forage is by allowing them to graze. To make grazing as efficient and cost-effective as possible, an appropriate grazing system is necessary. Establishing a rotational grazing system is the best way to optimize forage utilization and consumption on limited pasture acreage.
Conserved Forage Systems
In the majority of livestock enterprises, supplemental forage will need to be provided during some periods of the year. Forage produced in one part of the season can be conserved and stored for later feeding. The most common example of this is the production of hay. Hay is the product of cutting, drying, packaging, and storing forage. Hay must be dried to moisture levels of 15% or less in order to avoid deterioration (i.e., molding or rotting) during storage. Another common example of forage conservation is the production of silage. Silage is produced when a crop is successfully cut, packaged and stored in the absence of oxygen, and allowed to ferment. The fermentation process produces natural organic acids that stabilize the crop and prevents spoilage or deterioration of the crop. Silage can be produced in a number of different packages or storage methods. Examples include (but are not limited to) upright silos, bunker or pit silos, silage bags, and baleage.
Planning an Appropriate Forage System
Information provided on the University of Georgia's Forage website (link to http://www.caes.uga.edu/commodities/fieldcrops/forages/) can help you plan an appropriate forage system for your livestock enterprise(s). Recommendations are provided on that website on each element of the forage system, including:
- Production of the various forage crops that could be used
- Establishment recommendations
- Management strategies to provide good soil fertility
- Prevention or control of pests
- How to appropriately graze or harvest and store those crops, etc.
There are a number of other forage-related websites where one can obtain information on, for example, how to develop a management-intensive grazing system or how to produce switchgrass for forage and/or biomass for biofuel.
