Technical Abstract: A 2-yr grazing study was conducted to quantify forage available daily for cattle intake from a natural pasture managed under rotational grazing. Grazing was initiated around 5/1 and was managed with a rotation length of about 17 d each for cycles 1 and 2, and 30 d each for the rest. In 1994, under adequate moisture conditions, forage availability during 5/1-6/1, 6/1 18/15, 8/15-9/15, and 9/15-10/15 was 77, 66, 38 and 14 kg DM ha**-1 d**-1, respectively, resulting in a total yield of 8580 kg ha**-1 in 175 d. In 1995, a prolonged period of dry summer reduced the grazing season to 150 d. Forage supply dropped to 46 kg ha**-1 d**-1 during 6/1-8/15. Natural pastures in north central U.S. have the potential to provide significant amounts of forage for 5-6 months in a year under rotational grazing, but additional feed may be needed for a month or two during periods of stress.
