UW Milk Quality promotes an integrated, team-based approach to best manage udder health and milk quality. Producing high quality milk is not a one-person job. It takes farmers and their local dairy advisors to be able to evaluate, manage and improve milk quality. At UW Milk Quality, we develop tools and resources to help dairy producers meet their milk quality goals and increase farm profitability.
Go to Mastitis Control

Mastitis Control

Mastitis is detected by inflammation that is caused by infection by microorganisms and occurs in both clinical and subclinical forms. Mastitis remains the most common disease of dairy cows and treatment or prevention of this disease is the most common reason that antibiotics are administered to cows.

Go to Drug Residue Avoidance

Drug Residue Avoidance

Preventing antibiotic drug residues in milk and meat requires constant vigilance from all parties involved in the milk production process. The use of antimicrobials to treat food animals is under increased scrutiny by consumers, governmental officials and regulatory agencies and must be well justified.

Go to Teat End Health

Teat End Health

The teat canal is the primary physical and chemical barrier to invasion of mastitis pathogens into the udder. After repeated milkings, changes may appear in teat-end tissue, such as discoloring or callosity. Routinely evaluating teat health in the parlor will help reduce hyperkerotosis and teat barrel congestion in the herd.

Go to Machine Milking

Machine Milking

The main goals of machine milking are to remove the available milk from each cow’s udder quickly and completely, without slipping, with minimum discomfort to the cow and minimum damage to teats. Liner design, claw vacuum and pulsation greatly affect milking characteristics and performance.
