Equine hoof wall tubule density and morphology.

The research conducted a detailed study on the density and morphological features of tubules in the hoof wall of horses. The findings noted differences in the tubule density across different regions of the hoof and suggested the diagnostic potential of hoof horn clippings from live horses.

Study Sample and Procedures

• In this study, the researchers used 12 hoof samples taken from both living and deceased adult horses.
• The researchers prepared full wall thicknesses of the hoof wall histologically. These samples were taken from different positions of the hoof including the toe, medial quarter, and lateral quarter.

Examination of Tubule Density and Morphology

• The researchers carried out a comprehensive analysis of the tubules in defined areas of the hoof samples.
• Tubule density was calculated across three histologically defined areas: the stratum externum, stratum medium, and stratum internum.
• Morphologic features of the tubules were also described. These features were divided into zones based on their different cortical and medullary characteristics.

Revelations on Tubule Density

• The study observed an increasingly radial pattern in the tubule density across the walls of the horse hooves.
• There were notable regional differences in tubule density across different parts of the hooves, specifically in the toe, lateral and medial walls of the hoof.
• These findings constitutes the first study highlighting these regional differences in tubule densities.

Potential Diagnostic Value of Observations

• The study suggests that hoof horn clippings from live horses could have diagnostic or prognostic value. However, more research is required to establish this potential application of the study’s findings.
