Atrophic rhinitis: snout morphometry for quantitative assessment of conchal atrophy

Area of Science:

• Veterinary Anatomy
• Animal Science
• Morphometrics

Background:

• Conchal atrophy in pig snouts can impact animal health and welfare.
• Objective measurement is needed to assess factors influencing conchal atrophy.

Purpose of the Study:

• To present morphometric methods for quantifying pig snout conchal atrophy.
• To establish a reliable index for assessing atrophy extent.

Main Methods:

• Application of point counting or semiautomated planimetry.
• Analysis of photographic or impression prints of pig snout sections.

Main Results:

• Development of a continuous scale morphometric index for conchal atrophy.
• Generation of highly repeatable parametric data.

Conclusions:

• Morphometric techniques offer objective and repeatable assessment of conchal atrophy.
• Suitable for quantitative analysis of experimental treatments and management changes.
