Derner et al. (1994) noted that: 1) Rotational grazing provided greater managerial control over
the frequency and uniformity of tiller defoliation and ; 2)intensity of tiller defoliation was similar
between the rotational and continuous grazing systems. Thus higher range condition will be
maintained over the long-term in rotational system pastures; little bluestem will remain more
competitive and productive resulting from fewer defoliation events throughout the grazing
season (Derner et al., 1994). Also, rotational resting and rotational grazing should ensure
improved forage plant composition and productive potential so the effects of drought are
decreased and there is speedy recovery after drought (Teague et al., 2004).
Herbivores still express diet selectivity and thus patchy grazing to greater or lesser
degrees when managed under rotational grazing (Hunt et al., 2007). There is often a period of
time when rotational grazing performance lags behind that of continuously grazed animals as
herbivores better learn which plants to consume (Provenza, 2003a). Therefore, grazing periods
should be kept short enough so that the animals can maintain sufficient diet quality to meet
performance goals (Teague et al., 2008).
Successful grazing managers must optimize several ecological goals to attain sustainable
production goals (Heitschmidt and Taylor, 1991; Briske et al., 2008). Teague et al. (2008) argue
that these goals cannot be accomplished with continuous, season-long grazing in environments
that receive enough moisture to have growing periods of more than a few days. They further
suggest these goals should include: (1) Planned grazing and financial planning to reduce costs,
improve work efficiency, enhance profitability, and achieve environmental goals; (2) Providing
sufficient growing season deferment to maintain or improve range condition; (3) Grazing grasses
and forbs moderately during the growing season for a short period to allow adequate recovery;
(4) Timing grazing to mitigate detrimental effects of defoliation at critical points in the life cycle
of preferred species inter- and intra-annually; (5) Where significant regrowth is likely, grazing
