Hypothesis
How do circulating β-endorphin, ACTH, and cortisol levels respond to transport stress in stallions over different distances?
Conclusion
Short road transport induces significant increases in stress hormones in stallions, particularly β-endorphin, ACTH, and cortisol.
Supporting Evidence
- Circulating β-endorphin levels increased significantly after 100 km of transport.
- ACTH levels showed significant increases after 100 km and 200 km of transport.
- Cortisol levels increased significantly after all transport distances (100, 200, and 300 km).
- No significant differences were found between horses of different ages and breeds regarding hormone levels.
Takeaway
When stallions are transported, their bodies react by releasing stress hormones, which can show how stressed they are.
Methodology
Blood samples were collected from stallions before and after transport over distances of 100, 200, and 300 km to measure hormone levels.
Potential Biases
Potential bias due to the small sample size and lack of control for environmental factors during transport.
Limitations
The study did not account for individual variations in stress responses among horses.
Participant Demographics
42 healthy Thoroughbred and crossbred stallions aged 4 to 20 years.
