Range Sheep Production Efficiency Research

Research for healthier flocks, sustainable rangelands

At the Range Sheep Production Efficiency Research Unit (RSPER) in Dubois, Idaho, scientists study genetics, nutrition, and management practices that help sheep thrive. Their work supports ranchers with science-based solutions that improve flock productivity while conserving natural resources.

By combining innovation with decades of field-tested knowledge and collected data, the program helps ensure the resilience of sheep and the land they live on.
