- northwestern range operations
Intensive Production System
- farm flock operation
- lamb feedlot industry
What are Southwestern Range Operations
- use finer wool ewes, most adaptable
- very little supplemental feed
- impacts on profit: rain, predators, lamb crop, high quality fleece
What are Northwestern Range Operations
- similar structure to southwest, more supplemental feed
- goal: fast growing, easily marketed carcass sheep, coarser, heavier fleeced ewes, larger lamb crop
Farm Flock Sheep Production
Lamb Production: intensive management 150-200% lamb crop
Maternal (prolific, heavy milking)
Paternal (growth, muscularity)
Lamb Feedlot Industry
- Colorado & Texas led
- concentrate diets: high energy content
- goal= maximize average daily gain
