A grazing system regulates the length and timing of grazing periods in order to achieve specified outcomes with respect to forage and livestock production. Grazing systems must be tailored to fit the climate, soils, and vegetation of a given area as well as the objectives of the landowner. A good grazing system is simple and flexible, and it provides for adequate utilization of forage, uniform distribution of livestock, and economic practicality.
The objectives of a grazing system are to:
• Carry out deferment, or rest, over a period of time so that preferred forage plants can replenish energy storage in the roots and restore vigor.
• Obtain uniform forage use within each land unit. Remember the important guideline to use half and leave half. This allows enough leaves to remain for the grass to maintain healthy roots for the next year's growth.
• Allow management of both livestock, forage plants, and other components of the grazing system so that production is increased or maintained on a sustained yield basis.
The most commonly stated benefit of grazing systems is improved range condition resulting from increased plant vigor, seed production, and maintenance of preferred forage. These improved conditions increase forage yield and quality, thereby increasing animal production. The benefits gained from a grazing system will depend heavily on the site and forage species.
