  1. Improving Carcass Meritwhile maintaing profit

  2. Industry Challenge

  3. Profit • Income – expenses • Pounds sold per ewe • Control feed costs

  4. What is your market? • Niche/direct sales • lambs • carcass whole or half • piece at a time • Light slaughter lambs • ethnic channels • Traditional • sale barn, terminal, pool, packer direct, alliance

  5. Client taste and budget • Upscale versus cheap • Flavor intensity • Mild, coarse wooled, hair or meat type • Strong, fine wool or prolific • Age: younger is milder • Sex: more influence on old lambs (>10 mo)

  6. Selecting Terminal Sire • Growth, growth, growth • Livability, longevity • Carcass merit

  7. Selecting Terminal Sire • Options

  8. Crossbreeding • Capitalize on breed complementarity • Polypay ewes breed to Suffolk Rams • not • Suffolk ewes breed to Polypay Rams

  9. Marketing Lambs when Ready • to 70% of ewe weight • Average weight of sire breed females • Average weight of dams breed females • 175 lb Polypay + 250 lb Suffolk • (175+250)/2 = 137.5

  10. Seedstock producers • Improving your genetics to improve carcasses • NSIP, Lambplan, ultrasound • Carcass traits are highly heritable • rapid progress is possible • example: swine industry • Indirect selection via growth • fair comparisons
