How Does Your Calf Housing Stack Up?
The University of Wisconsin's School of Veterinary Medicine conducted a field study regarding air quality in calf units. In the trial, they measured the air quality within 13 calf facilities on Wisconsin dairy farms during winter months. The results were quite startling. Air quality, as determined by measuring the concentration of bacteria in the air of the calf units varied a lot - from very low to too many bacteria to accurately measure. Several factors were identified that contributed to air quality and solid recommendations were made from the research that can be applied to calf management on all farms, helping to reduce the incidence of respiratory infection.
