    • A project of the National Center for Appropriate Technology 1-800-346-9140 • www.attra.ncat.orgRotational GrazingBy Alice E. Beetz Rotational grazing is a grazing management strategy characterized by periodical movement of livestockand Lee Rinehart to fresh paddocks to allow pastures time to regrow before they are grazed again. Some popular rotationalNCAT Agriculture grazing systems include Management-intensive Grazing, multiple-pasture rotation, and short-durationSpecialists grazing (Gerrish, 2004; Hanselka, et al., no date). Other names include cell grazing and controlled grazing.November 2004 There are slight differences between how practitioners of each type of system may describe how theyUpdated Sept. 2010 work, but they are all basically predicated on adequate rest periods to allow for adequate forage regrowth.© 2010 NCAT Rotational grazing requires skillful decisions and close monitoring of its consequences. Modern electric fencing and innovative water-delivery devices are important tools. Feed costs decline and animal health improves when animals harvest their own feed in a well-managed rotational grazing system.

Economic benefits come from improved ani- mal health and increased production. Research confirms lower feed costs and fewer vet bills on most operations making this transition. Actual figures vary widely, depending on the profitability and forage condition under the old system. As the new system is fine-tuned, feed quality improves, quantity increases, and man- agement skills also grow. As a result, more ani- mals can be raised on the same acreage, translat- ing into more income for the farm.
