Summary

Cattle from live auctions show higher bruising and meat rejection than those from farms or dealers. Preslaughter handling significantly impacts meat quality, with bruising increasing with travel distance and lairage time.

Area of Science:

  • Animal Science
  • Meat Science
  • Food Quality

Background:

  • Preslaughter handling significantly impacts meat quality in cattle.
  • Bruising and meat rejection are important economic concerns in the beef industry.
  • Understanding factors influencing bruising is crucial for improving meat yield and quality.

Purpose of the Study:

  • To investigate the prevalence and causes of bruising in cattle carcases.
  • To compare bruising incidence across different sourcing methods (auctions, dealers, farms).
  • To assess the relationship between preslaughter handling, transport, lairage, and meat quality.

Main Methods:

  • Conducted two surveys involving over 16,000 cattle carcases.
  • Recorded bruising, stick-markings, and meat rejection due to bruising.
  • Analyzed data based on animal origin, transport distance, and lairage time.
  • Measured ultimate pH (pHu) in relation to bruising.

Main Results:

  • Animals from live auctions exhibited higher bruising and meat rejection compared to those from dealers and farms.
  • Stick-markings were more prevalent in market cattle (2.5%) versus farm cattle (0.9%).
  • Bruising incidence increased with travel distance and lairage time, affecting meat quality and pHu.

Conclusions:

  • Live auctions and extended preslaughter handling contribute to increased cattle carcase bruising.
  • Targeted interventions in handling and transport logistics can mitigate meat quality defects.
  • Reducing bruising is essential for improving economic returns and consumer satisfaction in the beef industry.
