Semen Collection and Analysis – The Science Behind Quarter Horse Reproduction
Every successful breeding begins with a thorough understanding of semen quality. Here’s how U.S. facilities are collecting and analyzing stallion semen for optimal results.
Reproductive efficiency in Quarter Horse breeding depends heavily on the quality of semen collected and processed. Modern laboratories and experienced technicians make it possible to assess stallion fertility with scientific precision.
1. The Semen Collection Process
Using a phantom mare and AV (artificial vagina), trained stallions are collected in a controlled, sterile environment. This process is designed for safety and efficiency.
2. Analyzing Semen Quality
Collected semen is evaluated for:
- Volume
- Concentration (sperm/mL)
- Motility (progressive movement)
- Morphology (normal shape and structure)
3. Extending and Shipping Semen
Once collected, semen can be:
- Used immediately for on-site AI
- Extended with nutrients and antibiotics for cooled shipping
- Frozen for long-term storage and international export
4. When to Repeat Collection or Adjust Nutrition
Low motility or abnormal morphology may indicate:
- Stress or illness
- Nutritional imbalances
- Need for collection frequency adjustment
