Heifer Mastitis: How to Help Heifers Calve Clean

Dr. Pamela Ruegg, Dairy Science Department, University of Wisconsin-Madison
Heifers that develop subclinical or clinical mastitis may be less productive and at greater risk for future mastitis cases. Thus, prevention of the initial infection should be one focus of heifer management programs. This paper reviews important concepts and research related to heifer mastitis.
