Hypothesis
Does a diet deficient in vitamin E increase the risk of equine motor neuron disease (EMND) in horses?
Conclusion
The study found that vitamin E deficiency is linked to an increased risk of developing equine motor neuron disease.
Supporting Evidence
- Ten out of eleven horses developed EMND within 44 months.
- Plasma vitamin E levels dropped significantly over time.
- None of the control horses developed EMND.
Takeaway
Horses that don't get enough vitamin E can get a disease that makes them weak and lose muscle. This study shows that not having enough vitamin E can lead to this problem.
Methodology
The study involved a field trial with 11 horses on a vitamin E deficient diet, monitored for EMND development over 44 months.
Potential Biases
Potential bias due to the small sample size and the observational design.
Limitations
The study's observational nature makes it difficult to establish a direct causal relationship between vitamin E deficiency and EMND.
Participant Demographics
Horses were primarily adult, with a median age of 10 years, and included various breeds.
