Area of Science:

  • Animal Science
  • Beef Production
  • Quantitative Genetics

Background:

  • Beef carcase merit is crucial for producer profitability and consumer satisfaction.
  • Objective measurement of carcase traits is essential for genetic improvement programs.

Purpose of the Study:

  • To develop and describe the Abtech Test, a progeny testing system for measuring beef carcase merit.
  • To establish objective methodologies for quantifying carcase composition and quality traits.

Main Methods:

  • The Abtech Test measures nine carcase characteristics in 12 steer progeny per sire at 300 days of age.
  • Five traits quantify carcase composition (e.g., lean meat yield, muscle-bone ratio).
  • Four traits evaluate carcase quality (e.g., eye muscle area, marbling, texture, fat color).

Main Results:

  • Objective measurements for carcase composition and quality traits were established.
  • Standardized adjustments were applied for comparisons (e.g., to 20% fat, common muscle weight).
  • The system provides a comprehensive assessment of beef carcase characteristics.

Conclusions:

  • The Abtech Test offers a robust system for objective carcase evaluation.
  • This progeny testing system has the potential for genetic improvement of beef carcases.
  • Standardized measurements facilitate accurate genetic parameter estimation and selection decisions.
