Summary

This study explored poultry walking biomechanics using a pedobarograph. Highest foot pressures were on the medial and back toes, not the metatarsal pad, offering insights into lameness causes.

Area of Science:

  • Animal Biomechanics
  • Poultry Science
  • Gait Analysis

Background:

  • Lameness is a significant issue in the UK poultry industry.
  • Objective biomechanical studies on poultry walking are scarce.
  • Understanding normal gait is crucial for addressing lameness.

Purpose of the Study:

  • To investigate the utility of a pedobarograph for gait analysis in poultry.
  • To objectively measure pressure distribution and forces during normal poultry walking.
  • To characterize poultry gait patterns for future lameness research.

Main Methods:

  • Utilized a high-resolution pedobarograph for poultry gait analysis.
  • Recorded pressure patterns across different regions of the avian foot.
  • Measured spatial gait parameters and net forces during locomotion.

Main Results:

  • Highest pressures were concentrated on the medial toe (149.4-218 kN m(-2)) and back toe (146.1-195.5 kN m(-2)).
  • The metatarsal pad experienced lower pressures (16.3-131.2 kN m(-2)), despite its association with lesions.
  • Maximum net forces reached 116-145% of bodyweight, comparable to human bipeds.

Conclusions:

  • The pedobarograph is a viable tool for detailed poultry gait analysis.
  • Specific foot regions bear higher loads during normal walking, informing lameness studies.
  • Quantitative biomechanical data provides a foundation for understanding and mitigating poultry lameness.
