Effective communication within an organization is essential for accomplishing tasks and for job performance and satisfaction. The dairy business is not an exception to this rule, especially as it applies to animal health and the many people responsible for animal care. Because dairy veterinarians work with the consolidating US dairy industry, their understanding of the many layers of management on these larger farms and the communication realities within them are critical to effective implementation of health-care decisions. Of particular concern are drug-use decisions at the calf level.
