Dr. Cook manages the Cow Comfort and Well-being Program with interests in a variety of subject areas related to the impact of the environment in which we keep our dairy cows on their health and behavior. Current projects include the effect of stall design on lame cow behavior, the effect of heat stress on stall use and lameness, interrelationships between hoof lesions, air quality in livestock buildings, the effect of pen moves on transition cow health and the development of a variety of transition cow health monitors.
Dr. Cook's primary clinical interests are focused on the impact of the environment on the well-being of the dairy cow. He provides a troubleshooting service to the dairy farms of Wisconsin for problems related to milk quality, clinical mastitis, lameness, and poor reproductive performance. He is also involved in appraising dairy facilities and offering advice on remodelling barns and building new barns to improve cow comfort and the care of dairy cattle.

Support Services
Anesthesia & Pain Management: Did you know that pain actually increases inflammation as well as healing time? Our anesthesia and pain management specialists coupled with state-of-the-art anesthetic equipment, most of which is equivalent to what is used in human hospitals, is what sets us apart from other veterinary hospitals.
Diagnostic Imaging: In consultation with the oncology, surgery, and medicine services, radiologists participate heavily in the diagnostic process. Our diagnostic imaging and radiation oncology service uses CT, DR (digital radiography), fluoroscopy, MRI, nuclear imaging and ultrasound to diagnose cancer, lameness, and many other medical conditions.
Laboratory: Clinical and anatomic pathology testing is available in the following areas: hematology, coagulation, cytology, clinical chemistry, endocrinology, urinalysis, microbiology, immunology, parasitology, necropsy (autopsy), and biopsy.
