[Computer-assisted analysis of pressure distribution on cattle claws].

Area of Science:

• Veterinary Medicine
• Biomechanics
• Animal Science

Context:

• Hoof health is crucial for dairy cow welfare and productivity.
• Quantifying pressure distribution can reveal potential lameness issues.
• Previous methods lacked precision in measuring sub-claw pressure.

Purpose:

• To introduce and validate a novel device for measuring sub-claw pressure distribution in dairy cows.
• To analyze pressure patterns in first and second lactation German Black and White cows.
• To identify key factors characterizing pressure distribution, aiding in lameness detection.

Summary:

• A new measuring device quantified sub-claw pressure distribution in 20 German Black and White cows (5 first lactation, 5 second lactation).
• Pressure data was collected over five weeks, with image processing used for analysis.
• Average pressure was ~19 N/cm², with maximums of 59 N/cm² (1st lactation) and 56 N/cm² (2nd lactation).
• A
• gradient factor
• was developed and showed promise in identifying inhomogeneous pressure distributions.

Impact:

• Provides a novel, precise method for assessing hoof pressure in cattle.
• Offers insights into lactation-stage differences in weight-bearing patterns.
• The
• gradient factor
• could become a valuable tool for early lameness detection and herd health management.
