Recumbency in Holstein Calves
April 3, 2023
Researchers at Penn State University have been collaborating with colleagues at USDA’s Agricultural Research Service to study a new genetic defect in Holstein cattle. This defect is characterized by otherwise healthy animals that are unable to stand. This condition, currently called calf recumbency, has proven to be more complex than other known genetic defects.
