Summary
Assessing dairy cow lameness is crucial for welfare. This review evaluates subjective and objective gait assessment methods, highlighting factors influencing gait analysis accuracy for better herd management.
Area of Science:
- Veterinary Science
- Animal Welfare
- Biomechanics
Background:
- Lameness is a significant welfare concern in dairy cows, driving research into gait assessment.
- Existing gait assessment methods vary in reliability and practicality for on-farm use.
- Both subjective and objective approaches have limitations affecting widespread adoption.
Purpose of the Study:
- To critically review current gait assessment methods for dairy cows.
- To evaluate the reliability and validity of existing gait measures.
- To identify research gaps in lameness and gait analysis.
Main Methods:
- Literature review of gait assessment techniques in dairy cattle.
- Analysis of factors influencing gait variability.
- Discussion of pathological and environmental impacts on locomotion.
Main Results:
- Subjective gait assessment is immediate but observer-dependent.
- Objective methods offer accuracy but require advanced technology.
- Cow-specific (conformation, size, udder fill) and environmental (flooring) factors impact gait.
Conclusions:
- Accurate gait assessment is vital for identifying lameness and improving dairy cow welfare.
- Understanding factors causing gait variation is key to reliable lameness detection.
- Further research is needed to refine and validate practical gait assessment tools for farms.
