The list represents an excellent resource but it is not without limitations. S o, if you are interested in the performance of the product you are using or are considering using there are two options. First it may be on the list, meaning it was tested and reviewed and published for the world to see. If it is not on the list ask the manufacturer about what test results they have, based on either the Experimental Challenge or Natural Exposure protocols. Do not rely on Protocol A results, because they are not an appropriate measure of field performance or teat dip efficacy.
Most manufacturers are able to produce appropriate reports on their various teat dips.
It is not correct to compare test results from evaluations that may have been done at different locations, during different seasons in different years. These factors may play a big role in the performance. Look for trends rather than absolute numbers. The difference may be a function of weather, virulence of the bacteria cultures being used and immune status of the cattle. So don't be misled by apples to oranges comparisons.
