Udder Cleanliness and Somatic Cell Count
USU Dairy Extension Newsletter
I am always concerned when I visit dairies and see dirty cows. Dirty cows are an indicator of udder health problems. The French reported a study where they categorized commercial dairies on the basis of 5 levels from clean to very dirty. Not surprisingly, there was a linear relationship between increased somatic cell count and dirty udders. Others have found similar relationships. I believe most dairy farmers won't argue too strongly over whether this association is real, but they may not look at the situation in a systematic, measurable way. I always like cheap, easy and useful management tools to assess different aspects of a dairy. This article describes a quick, easy way to determine the cleanliness score for the cows on your dairy.
