Grass-Based Dairy

Recognizing the difficulty of representing a rotational grazing system on small experimental plots, WICST early on decided to study the system in greater depth at a nearby farm.  Altfrid and Sue Krusenbaum started farming in 1990, and in that year members of the WICST project and others formed a team to study their operation.

Between 1992 and 1995 the Krusenbaums experimented with (and eventually adopted on all their production acreage) management-intensive rotational grazing.  They also decided to switch to a mostly seasonal milking operation and outwintering of the cows to reduce their work load.  In 1996 they built a New Zealand-style milking parlor.  Between 1990 and 1997, they expanded their herd from 37 to 120 cows. 

Several times a year various researchers (in economics, dairy science, dairy forage, soils, agronomy, agro-ecology) meet with the farm family to discuss the progress of the farm, results of data analysis, and past and upcoming management decisions.  The result is an in-depth portrait of a complex and evolving dairy enterprise.  For further information contact Altfrid Krusenbaum at akrusenb@elknet.net or Josh Posner at the UW Department of Agronomy at jlposner@facstaff.wisc.edu
