Management-Intensive Rotational Grazing of Dairy Heifers on WICST (1999-2000)

Management-intensive rotational grazing (MIRG) is a low input form of dairy herd management that is increasing throughout the United States. In Wisconsin, about 23 percent of dairy farmers used MIRG last year, more than triple that since 1993 (Jackson-Smith and Powell, 1999). Of the three dairy forage systems represented in the Wisconsin Integrated Cropping Systems Trial (WICST), rotational grazing is the lowest input system which measures productivity in terms of animal performance and forage production. Long-term effects of animals on soil and vegetation are also being monitored.
