It is important to understand the normal distribution of teat ends and not make rash decisions or changes when SCC goes up, especially in winter. Teat end changes can occur rapidly, in winter with dehydration and cracking, and other times with acute machine problems. This is usually associated with weather changes and is accentuated through the normal milking process since milking changes the tissue hydration status and enhances.this drying/ cracking. Controlling or minimizing the weather effects through proper facilities and environments is the #1 objective. Proper milking equipment and practices are critical to minimizing negative effects on teatends and mastitis. Some practices may need to be altered or adapted during cold weather(dipping, blotting, etc.) Advantages and disadvantages (including costs and enhanced other risks) should be carefully examined when evaluating using new technologies or products like teat dips. To date, we have found no total cessation of cracked teats during winter unless cows could be kept in a warm environment (>40°F) with no access to cold temperatures. This is unachievable in most situations.
