Hypothesis
Does varying light exposure durations affect ram sperm quality?
Conclusion
Extending the light duration to 16 hours significantly improves ram sperm quality.
Supporting Evidence
- The 16 h light group showed significantly improved sperm motility and concentration compared to the control group.
- 345 different metabolites were identified between the control and 16 h light group, with 273 upregulated.
- The testosterone levels in the 16 h light group were significantly higher than in the control group.
Takeaway
If rams get more light, especially 16 hours, their sperm gets better, which is good for making baby sheep.
Methodology
25 rams were divided into five groups exposed to different light durations (12, 14, 16, 18, 20 hours) and sperm quality was assessed after three months.
Participant Demographics
Healthy adult rams, approximately 2 years old, average weight 80 kg.
