Mastitis Control and Milk Quality

About This Course

Welcome to the Bovine Mastitis MOOCs series!

As you know mastitis is a very costly disease on dairies. It is a complex, multi-factorial health problem and, all around the world, a large number of scientists, and their graduate students, are conducting research on this disease.

For that reason, experts from more than 20 countries have decided to work together to produce this series of three MOOCs, designed for graduate students, to give them the knowledge they need to initiate their research program. Of course, these MOOCs will also be useful for dairy practitioners, teachers, and for individuals that already have a solid scientific background, and are interested in learning about bovine mastitis.

This third MOOC titled "Mastitis control and milk quality" will discuss mastitis prevention and control strategies including: general control plans, mastitis prevention in heifers prior to first calving, mastitis prevention during the dry period, efficient milking routine, vaccination, treatment of clinical and subclinical mastitis, as well as strategies to reduce use of antimicrobials.  Mastitis economics and milk quality will also be discussed.

We hope this series will answer all your questions and will be useful for your professional development. Let's start the last MOOC of the series: "Mastitis control and milk quality"!

Target audience

This course is designed primarily for graduate students conducting a master or doctoral project on udder health. The objective is to equip them with the knowledge they will need to conduct their research.

This course could also be useful for veterinarians, as they provide an opportunity to deepen the basics and access to cutting-edge knowledge for continuing education. The same applies to teachers in agriculture and animal health. Similarly, anyone with a scientific background and an interest in udder health will find high-level notions within the course.
