Summary
This study effectively induced lameness in meat goats using two methods, providing valuable insights into pain response and characterization for improved livestock health management.
Area of Science:
- Veterinary Medicine
- Animal Science
- Livestock Health
Background:
- Lameness is a significant welfare and economic issue in livestock.
- Accurate assessment of lameness and pain response is crucial for effective treatment strategies.
Purpose of the Study:
- To evaluate two distinct models for inducing lameness in meat goats.
- To assess various measurement techniques for characterizing induced lameness and animal response.
Main Methods:
- Lameness was induced via intraarticular injection of amphotericin B (Amp-B) or kaolin-carrageenan (K-C) into the distal interphalangeal joint.
- Response was measured using behavior scoring, visual lameness scoring (VLS), infrared thermography (IRT), pressure mat analysis (PMT), and plasma cortisol (CORT) levels.
Main Results:
- Lame goats exhibited significantly higher VLS, hoof temperatures (IRT), and plasma cortisol levels compared to controls.
- Pressure mat analysis revealed decreased force, impulse, contact pressure, and contact area in the affected limb of lame goats.
Conclusions:
- Both induced lameness models reliably produced varying degrees of lameness in meat goats.
- The evaluated methods (VLS, IRT, PMT, CORT) are effective in characterizing induced lameness and animal response.
