Clinical cases can occur during the dry period and quarters that are not treated may have lower production in the next season. Observe cows weekly for changes in the udder.

Guideline 19 and Technote 19 provide practical and technical information on:

• Visually observing udders for swollen quarters at least once a week
• Manually checking all udders fortnightly for the first 4-6 weeks of the dry period
• Applying teat spray after checking udders.
