Animal health decision-making rarely involves a single “right” answer. Most animal health problems can be addressed in multiple ways, each with different implications for animal welfare, farm performance, risk, and cost. At the same time, animal owners and farmers operate within real constraints, including limited budgets, labour availability, time pressures, regulatory requirements, and competing priorities both on and off the farm. In this context, good clinical knowledge alone is often not enough to support effective and sustainable decisions.
Animal health economics provides a structured way to navigate these trade-offs. Rather than focusing only on the biological effectiveness of an intervention, economic analysis asks how different options perform relative to one another when costs, benefits, uncertainty, and timing are considered together. This allows farmers, veterinarians, and other animal health professionals to move beyond intuition or habit and to compare management options in a transparent and systematic way.
Importantly, animal health economics is not about choosing the cheapest option or reducing animal care to financial terms alone. It is about clarifying value. An intervention that is biologically sound may still be impractical, unaffordable, or poorly aligned with a client’s goals. Conversely, a modest change in management may generate substantial benefits when applied at the right time or scale. Economic analysis helps make these distinctions explicit, supporting decisions that balance animal health and welfare outcomes with financial and operational realities.
Traditionally, animal health economics has been most commonly applied in production animal systems, where animals generate clearly defined economic outputs such as milk, meat, fibre, or offspring, and where the financial consequences of disease and intervention are often more readily quantified. However, the same principles are equally relevant in companion animal and equine practice. In these settings, decisions are frequently shaped by strong emotional and social bonds between owners and their animals, which can make economic considerations both more complex and more sensitive. While outcomes such as companionship, quality of life, and emotional wellbeing are difficult to express in monetary terms, financial constraints still exist and must be balanced against these values. Increasing availability of pet insurance, third-party payment plans, and staged treatment options has expanded the range of feasible interventions, further reinforcing the importance of structured economic thinking to support clear, realistic, and compassionate decision-making in companion animal practice.
For the purposes of this guide, the primary focus is on production animal systems, where animal health decisions have direct and measurable implications for farm performance, business viability, and system sustainability. These settings provide a practical and transparent context for developing economic reasoning skills, as production outputs, costs, and timelines are often more clearly defined. While the examples and case studies that follow are drawn largely from dairy, beef, and sheep systems, the underlying principles and analytical approaches are broadly applicable across veterinary contexts and can be readily adapted to other species and practice settings.
The basic principles behind raising production animals is that you put inputs like feed, veterinary care, and housing into the system (costs) and the animal generates products that have a marketable value (benefit) to the farmers. The presence of disease in the animal can result in it taking more resources to generate the same amount of product (increased costs) or a reduced quality or quantity of outputs (decreased revenue) leading to the farms producing much less efficiently than they would in a disease free state.
Improving animal health at the farm level often requires a shift in mindset from viewing animal health care as a short-term expense used to fix individual problems, to recognising it as an investment in the long-term health, welfare, and performance of the production system as a whole. Developing economic reasoning to support these decisions can feel challenging at first, particularly for those without formal training in economics, but breaking the process into clear, structured steps helps make animal health economics an accessible and practical tool for real-world decision-making.
Because animal health decisions involve multiple options, competing objectives, uncertainty, and limited resources, economic reasoning is most effective when applied in a structured and systematic way. The approach used in this guide follows a six-step framework that supports transparent, consistent, and defensible animal health economic analyses across a range of decision-making contexts.
With these principles in mind, the following sections walk through each step in detail, providing a practical guide to applying animal health economics to real-world decision-making.
