Extending the grazing season can reduce production costs (Fowler and Stout, 1990). Labor for the winter period can be reduced to 25% of conventional wintering of beef cows in Ohio (Van Keuren, 1970). Rotational grazing takes about three hours/acre/year versus hay production which requires seven hours/acre/year (Undersander et al., 1991). The cost for feeding hay or stored feed is between $0.75 to $1.00 a day per cow, compared to $0.20 to $0.25 a day per cow for winter grazing fescue. A well-planned grazing program can provide stockpiled pasture well into winter across much of the Upper South and Lower Midwest (Gerrish, 1996).
