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.

Managing Mastitis: The Pathogen Series: Mycoplasma species

The new UW Milk Quality series, “Managing Mastitis: The Pathogen Series” brings to light the various pathogens that cause mastitis on dairy farms. Each episode introduces a new pathogen and provides treatment and control recommendations for decreasing the risk of infection within herds. This first episode in the series focuses on the Mycoplasma species.

Managing Mastitis: The Pathogen Series: Staphylococcus aureus

This second episode focuses on diagnosis, transmission, treatment and control of mastitis caused by Staphylococcus aureus.

Managing Mastitis: The Pathogen Series: E. coli

As part of the UW Milk Quality continuing series on mastitis pathogens, Dr. Pamela Ruegg introduces an important organism called E. coli. E. coli is one of the causes of clinical mastitis occurring in dairy cattle, and in this episode Ruegg discusses its diagnosis, treatment and prevention.

Managing Mastitis: The Pathogen Series: Klebsiella

UW Milk Quality releases the fourth episode in its Managing Mastitis: The Pathogen Series. Klebsiella is a common Gram-negative pathogen in clinical mastitis cases. This video discusses the environmental sources and potential contagious transmissions of Klebsiella and control and treatment options for your dairy herd.

Managing Mastitis: The Pathogen Series: Environmental Streptococci

In the latest episode of the Managing Mastitis series, Dr. Pamela Ruegg from the University of Wisconsin discusses diagnosis, treatment and effective control programs for Environmental Streptococci pathogens. Learn why the focus should be on prevention with special emphasis on the dry period and which cows are most at risk of infection.
