Milk Secretion, Mastitis and Quality

Milk Secretion, Mastitis and Quality is team-taught by four experts in the field of dairy health and is open to anyone who has had a basic course in dairy/animal science, physiology, or consent of the instructor. Experts include: Dr. Tom McFadden, Dr. Geoffrey Dahl, Dr. Dawn Morin and Dr. Dick Wallace.

This is an advanced course covering the physiologic basis of mammary growth, milk secretion and udder health. Topics covered include mammary gland anatomy, hormonal control, causes and control of mastitis, milk harvesting and milk quality. The course will be delivered via CD-ROM and web-based synchronous discussion.

By using the Web as a teaching tool, students have access to class notes, lectures and handouts 24 hours a day, seven days a week. Students have the option to print all material for the class. Weekly lectures are recorded and archived if you should happen to be late or miss one of the weekly "live" sessions. This course was previously listed as 375 and 499.

Training Modules

Training modules for the class are on a CD-ROM and are on average 10 to 15 minutes in length. The modules are lectures given by the particular subject matter expert. There are approximately five training modules assigned per week. It is in the student's best interest to review the training modules before the weekly discussion.
