Responsibilities

Clinical and teaching activities are in the area of applied dairy nutrition. Most of these activities include solving nutritional problems on dairy farms throughout Wisconsin.

Clinical Interests

Clinical service is directly to dairy herds with nutritional problems. Herds throughout Wisconsin and neighboring states are consulted. Most of these consultations include a visit to the farm and a written report of the recommendations. I am also involved in delivering regular nutrition and production medicine services to one of the herds enrolled in the core herd program.
