Conclusion: Making the Right Choice

Decision Framework:

1. Define your endpoint: Are you selling weaned calves, yearlings, or finished beef? Are you maximizing milk components or volume?

2. Match genetics to environment: Heat-tolerant genetics for the South; high-production for controlled environments

3. Calculate true cost: Include conception rates, not just semen price

4. Track results: Keep records on AI sires used, conception rates, and offspring performance

5. Adjust annually: Review sire selection based on previous year's results

Bottom Line: The "best" semen is the one that fits your specific production system, market, and management capability. A $25 straw that conceives at 65% and produces marketable offspring is better than a $200 straw that doesn't fit your program.
