  • Direct losses include:
    • Mortality of breeding or production animals
    • Reduced production efficiency eg reduction in feed conversion, fertility rate, growth rate etc. May be presented as a higher rate of inputs to sustain required outputs.
    • Reduction in product quantity (fewer offspring, less milk, less eggs, less meat or fleece etc), or reduction in product quality (poor hides because of tick damage, discarded milk because of mastitis etc)
    • Costs incurred in diagnosing and treating sick animals (veterinary fees and drugs costs).
  • Indirect losses include:
    • Additional costs for disease control measures or eradication
    • Human health costs associated with health impacts from zoonotic diseases (BSE, HPAI, Salmonellosis) or from unintended consequences of control measures (chemical residues in products)
    • Negative animal welfare impacts of disease or control measures
    • Trade restrictions due to disease and control measures
    • Loss of consumer confidence in a market sector leading to reduced demand or altered consumer behaviour
    • Range of possible negative effects such as a move towards production systems that may be resistant to disease but that are relatively inefficient or have other potentially negative effects (use of resistant genetics with reduced production efficiency).
