Bruising in cattle transported over long distances

E Yeh, B Anderson, P N Jones

    The Veterinary Record
    |August 5, 1978
    PubMed
    Summary

    Cows are more susceptible to bruising than bullocks, with bruising increasing in cows on longer journeys. Factors like carcase weight or temperament did not explain these differences in bruising.

    Area of Science:

    • Animal Science
    • Agricultural Research
    • Meat Science

    Background:

    • Bruising in cattle carcases is a significant economic concern in the meat industry.
    • Understanding factors influencing bruising susceptibility is crucial for improving meat quality and reducing losses.

    Purpose of the Study:

    • To investigate the relative susceptibility of cattle of different sexes (bullocks and cows) to bruising.
    • To determine if journey duration influences bruising levels differently between sexes.

    Main Methods:

    • Five trials were conducted, involving three groups of cattle: bullocks, cows, and mixed groups.
    • Bruised tissue was trimmed from carcases, and its weight was measured.
    • Data on journey duration, carcase weight, temperament, and oestrus behavior were considered.

    Main Results:

    • Cows exhibited significantly greater amounts of bruised tissue compared to bullocks.
    • Bruising in cows increased with longer journey durations, a correlation not observed in bullocks.
    • Differences in carcase weight, temperament, or "riding" behavior during oestrus did not significantly contribute to the observed bruising differences.

    Conclusions:

    • Female cattle (cows) are more prone to bruising than male cattle (bullocks).
    • Extended transport duration exacerbates bruising in cows.
    • Further research may be needed to fully elucidate the physiological or behavioral mechanisms behind sex-based bruising differences.
