Adequate teat preparation before cluster attachment is key to maintain healthy udders and milk quality.
• A pre-milking udder preparation routine should stimulate milk letdown and minimize the risk of infection and contamination of milk by bacteria and soil.
• Work over the years has shown that clear benefits in udder health and milk quality are obtained when applying a full milking routine (Tables 1 and 2).
• Even though a “one fits all” routine may not be applicable, a review of key udder preparations is presented to remind farmers of the importance of creating and implementing an udder preparation routine before milking.
• Maintaining healthy udders and producing high quality milk should be a passion for all dairy producers. Key points presented below are part of a full pre-milking routine.
Key Points for Prepping Teats Before Milking
• Milkers’ hands should be clean before milking.
-Action: Milkers should wash hands before milking and wear disposable gloves.
• Forestripping cows helps improve milk letdown and identify abnormal milk.
-Action: Remove first 2 to 3 streams of milk into a strip cup and check to see if milk displays normal appearance (Figure 1).
• Stimulating teats before milking will help decrease milking time and increase milk yield.
-Action: Remove debris and clean teats before milking by using a combination of the following: dry / wet paper, foam cleaner, and /or teat sanitizer (Table 2 and Figure 1).
• Milking soiled quarters will increase the chances of mastitis and contamination of milk.
-Action: Thoroughly clean / sanitize teats before milking by using a foam cleaner or teat sanitizer. Maintain cows in a clean environment. Change bedding material regularly and make sure manure in alleyways and cubicles is minimal.
• Teats must be clean and dry before attaching the milking cluster.
-Action: Thoroughly clean / sanitize teats before milking by using a foam cleaner or teat sanitizer. Use a dry paper towel or cloth to remove debris or product present in teats before attaching the milking units (Table 2).
• Use products that have been tested and that are approved for the application.
-Action: Check that your milking routine and expected outcomes make use of approved products (Table 2).
• Keep a consistent routine.
-Action: Define a pre-milking routine that best fits your needs. Follow-up and make improvements, if necessary, by reviewing milk quality and animal health records.
