2024: Cow-Calf Contact Effects on Cow Udder Health and Calf Pneumonia Risk
Most U.S. dairy farmers follow current management recommendations to immediately separate a cow from her calf after she gives birth. However, recent research suggests that prolonged cow-calf contact may reduce the risk for mastitis in cows and respiratory disease in calves, lessening the need for antibiotics. While addressing food insecurity is of paramount importance globally, it is critical to ensure that solutions do not come at the detriment of livestock health and welfare, that they fulfill sustainable production needs, and that they meet consumer expectations. This project will evaluate differences in health and behavior between cows and calves that have prolonged contact or are separated immediately after birth. In addition to participating in collaborative research, an undergraduate will lead an independent part of the study focusing on cow udder health and milk production, or calf lung health.
