    Study Notes

    Farm Animal Illnesses and Disruptions

    • Altered rainfall patterns (flooding, droughts, extreme weather) disrupt social systems and animal health.
    • Heat stress impacts milk production, weight gain, and fertility in cattle.
    • Heat stress affects cattle worldwide, leading to management system adaptations.
    • Increased global temperatures will cause more days of heat stress for cattle.

    Contemporary Livestock Production

    • Farms concentrating on one or two livestock species are economically more important.
    • Large piggeries, feedlots, and large dairies are common.
    • Traditional multi-species farms are less common.

    Veterinary Clinical Epidemiology

    • Clinical epidemiology helps understand disease patterns and risk factors.
    • Understanding disease spread is crucial for biosecurity and control.
    • Knowing risk factors helps determine modifiable factors for disease reduction.
    • Applied epidemiology tools help identify, quantify disease risks, predict treatment responses, and evaluate control measures.

    Veterinary Input to Animal Productions

    • Veterinarians need to consider complex factors like climate, politics, and economics in livestock production.
    • Veterinary input must reflect contemporary livestock production contexts.

    Equine Practice

    • Advanced diagnostics and treatments are available for horses.
    • Understanding of equine infectious and contagious diseases has improved.
    • Economically important diseases impacting large numbers of horses affect athletic events and sales.
    • Infectious respiratory diseases and other equine diseases are important concerns.

    Disease Control and Prevention

    • Veterinarians advise on disease control and prevention programs, like herd biosecurity and vaccinations.
    • Strategic use of anthelmintics in cattle and sheep is advised.
    • Maintaining optimum productivity through animal health management and herd health programs are recommended.
    • Veterinarians advise on nutrition, breeding, and general management practices, often impacting animal health.
