In simple terms, I had described the desired outcome of the pre-milking teat sanitation. The average surface area of a cow's teat is approximately 7 to 8 square inches or 28 to 32 square inches of teat surface area per cow. For an average 100-cow Minnesota dairy, this will be a total of about 20 square feet. For every dairy farm, this may be the most important surface area on the farm to keep clean and dry.
If you have had to tell someone the same thing ten times, you need to redesign your message. My experience tells me that there are a lot of opportunities to improve employee compliance by more creative communication. I suggest that every dairy herd owner, manager, educator and consultant read the book, Made to Stick: How Some Ideas Survive and Others Die.
