Abstract

OBJECTIVE

To evaluate the radiographic thickness of the dorsal hoof wall in normal draft horse feet.

ANIMALS

33 adult draft horses with no history of laminitis, no clinically obvious lameness, and visibly unremarkable front feet were included.

METHODS

This was a prospective, descriptive study of clinically normal draft horses’ front feet. Lateromedial radiographs were acquired of the front feet. A ratio of the dorsal hoof wall thickness to the length of the distal phalanx (DHWP3 ratio) was calculated.

RESULTS

The dorsal hoof wall thickness to length of the distal phalanx was calculated as 0.33 ± 0.03 (range of 0.28 to 0.39) in this population of draft horses.

CLINICAL RELEVANCE

With very few exceptions, the heterogeneous population of draft horses evaluated in this study had a DHWP3 ratio greater than previously published values in lighter breeds (< 0.30).
