Dairy Claw Lesion Identification
The Dairy Claw Lesion Identification Poster was developed through a combined effort by Zinpro Corporation, and the International Lameness Committee. It represents the first global consensus for claw lesion identification, naming convention and record keeping practices. By adopting consistent terminology throughout the world, both the prevalence and economic impact of various lesions will be easier to track and assess.
Proper Identification is Critical
Dairy claw lesions are organized into two categories: infectious and non-infectious. Effective claw lesion management starts by evaluating which category is most prevalent in a particular herd. Since corrective action plans must be appropriate for the category of lesion present, proper lesion identification is critical.
Single-letter Abbreviation, Global Application
The Dairy Claw Lesion Identification Poster features the use of a consistent, single-letter abbreviation for each lesion. Historically, the two most common lesion identification systems (AABP and ABC) are based on two letter abbreviations; however, dairy record keeping practices function more effectively with a single letter due to program character space constraints. With the single letter abbreviation system, lesion prevalence can be more accurately tracked and assessed worldwide by using a common letter for each lesion abbreviation.

It features close-up color photographs, detailed descriptions, claw zones and single letter abbreviations for the 14 most common non-infectious and infectious claw lesions.
Most Common Dairy Claw Lesions
Following is a summary of lesion names and common signs for the 14 most common non-infectious and infectious claw lesions in dairy cattle. The single letter lesion abbreviation is listed in parenthesis after the lesion name. For reference, the claw zone(s) affected by each claw lesion are also listed, as this provides the ability to cross reference lesion type with the particular claw zone(s) where each lesion occurs, resulting in more accurate lesion identification.

The Role of Trace Minerals in Dairy Hoof Health
Trace mineral nutrition plays a critical role in building and maintaining strong, healthy feet. For example, zinc and copper are essential nutrients for developing healthy claw horn tissue, while zinc and manganese play a crucial role in wound healing. Research has shown that feeding a combination of trace minerals (Zn, Mn, Cu and Co) in a highly available complexed form helps decrease both the incidence and severity of common claw lesions.
