Simmental
A large continental breed used for growth, milk, and versatile beef or dual-purpose programs.
Overview
Simmentals brought frame, milk, and gain into U.S. herds from the 1960s–70s continental boom. Modern American Simmental and SimAngus composites balance maternal traits with terminal performance. Fullblood European types can be more dual-purpose.
- Origin
- Simme Valley, Switzerland
- Also known as
- Fleckvieh (related dual-purpose types)
- Mature cow weight
- 1,300–1,700 lb
- Mature bull weight
- 2,200–2,900 lb
- Default planning weight
- 1,450 lb · 1.15 AUE
Growth
High growth and yearling weight potential. Excellent for terminal sires and progressive commercial herds.
Milk
Among the higher-milking beef/dual breeds — boosts weaning weights but raises cow maintenance.
Temperament
Variable; select for disposition. Larger cattle need stout facilities.
Climate
Adaptable with nutrition matched to size. Large dark cattle still need shade in humid heat.
Feed
Higher dry-matter appetite and maintenance than British cows. Underfeeding large frames hurts reproduction.
Pasture
Need productive pasture or supplement to express genetic potential. Stocking rates should reflect higher AUE.
Management
Calving ease on heifers needs attention with larger sires. Use breed EPDs and composite options (SimAngus) for balanced herds.
Strengths
- Growth and muscling
- Milk-driven weaning weights
- Versatile purebred and composite use
Limitations
- Higher feed and land demand per cow
- Heifer calving management
- Facility strength for large cattle
