🧬 Use in Crossbreeding
- Romanov sheep are used in many countries to improve local meat or low-prolificacy breeds.
- Crossbreeding them with Iranian breeds (e.g., Afshari or Mehraban) results in:
- Increased litter size,
- Earlier maturity,
- And higher flock economic efficiency.
💰 Economic Summary
| Indicator | Approximate Performance |
|---|---|
