Veterinary Antimicrobial Susceptibility Testing Market Size, Share, and Industry Analysis By Product (Equipment, Consumables & Accessories (Culture Media, Disks & Plates, and Others)), By Animal Type (Livestock (Cattle, Pigs, and Others) and Companion (Dog, Cat, and Others)), By End-user (Veterinary Reference Laboratories, Veterinary Research Institutes, and Others), and Regional Forecast, 2026-2034

The global veterinary antimicrobial susceptibility testing market size was valued at USD 1.24 billion in 2025. The market is projected to grow from USD 1.34 billion in 2026 to USD 2.53 billion by 2034, exhibiting a CAGR of 8.2% during the forecast period.

The global veterinary antimicrobial susceptibility testing market expands due to escalating Threat of Antimicrobial Resistance (AMR). The products included in Veterinary Antimicrobial Susceptibility Testing (AST) include laboratory techniques and reagents that are used to identify the efficacy of the antimicrobial agents and their capability to fight the bacteria that have been isolated in an animal source.

The rising demand for animal-sourced food products in the world (meat, milk products, and eggs) called for productive, healthy animals. Though an efficient practice, intensive farming may result in such an environment in which infectious diseases transfer very fast.

Veterinary Antimicrobial Susceptibility Testing Market Driver

Antimicrobial Resistance (AMR) Increaseto the Defense Ministry to Expand the Market

The global AMR crisis that is increasingly gaining momentum can be taken as a major growth motor behind the veterinary AST market. The inappropriate and excessive usage of antibiotics on food-producing animals and companion animals has been unintentionally cultivating and facilitating the occurrence and the dispersion of the drug-resistant bacteria.

Increase in the Number of Companion Animals to Advance the Market

The other important exhibition of the veterinary AST market is the consistent and high growth of the number of companion animals in their possession around the globe. There is an observed change in the way pets are perceived, as they are more and more being considered as part of the family, and owners of pets are more willing to spend money on their well-being. This means that there will be an increased need to have advanced veterinary services, such as complex diagnostic services.

Veterinary Antimicrobial Susceptibility Testing Market Restraint

High Cost of Testing toPose Potential Impediments on this Market

One of the huge deterrent forces to the veterinary antimicrobial susceptibility testing (AST) market is the huge cost of such diagnostic practices. This is very expensive, and this can be explained using various factors, such as the specialized equipment (especially automated AST systems) necessary, the high reagents and consumables necessary and the requirement of highly trained staff to undertake and interpret the tests.

Veterinary Antimicrobial Susceptibility Testing Market Opportunity

Existence in Emerging Markets to Create Opportunity in this Market

The large potential of the veterinary antimicrobial susceptibility testing (AST) market is in expansion to emerging economies of the Asia Pacific region, Latin America and Africa. These areas are typified by livestock populations that have been rising rapidly due to both the growing need for animal protein and the burgeoning of middle classes in most of the regions, resulting in a subsequent increase in pet keeping.

Segmentation

Key Insights

The report covers the following key insights:

• Market drivers, restraints and opportunities
• Influence of key industrial players and key developments
• Escalating Threat of Antimicrobial Resistance
• Rising Demand for Animal-Derived Products

Analysis by Product

By Product, the Veterinary Antimicrobial Susceptibility Testing market is divided into Equipment, Consumables & Accessories, Culture Media, Disks & Plates & Others

The equipment segment of the veterinary AST market includes mainly automated and semi-automated equipment intended to carry out AST. The growth of this segment has been mainly motivated by the growing need for quicker, more accurate and uniform test outcomes.

The segment of consumption and accessories includes almost all the variety of products used in AST devices regularly. The growth of this segment is in direct proportion to the total amount of AST done. All the tests performed, including manual tests and automated ones, demand the constant application of these disposable or limited-use items.

Analysis by Animal Type

Based on Animal Type, the market is divided into Livestock (Cattle, Pigs & Others), Companion (Dog, Cat & Others)

Livestock in the vet AST market includes the testing of livestock species that are mainly produced in the food chain, like cattle, poultry, swine, and another aquaculture. This sector is recording a healthy development owing to the increasing demand for animal protein in the world, which requires healthy and efficient production of livestock.

The exotic animal industry, which includes pets like cats, dogs, horses, and other pets under small animals, is one of the most growing spheres of veterinary AST. This growth has mostly been driven by the trend of humanising pets by their owners, who consider pets like an addition to their family and are ready to spend heavily on their health affairs.

Analysis by End-user

Based on End-user, the market is divided into Veterinary Reference Laboratories, Veterinary Research Institutes & Others

Veterinary reference laboratories are established, centralised specialist facilities which offer a full range of advanced diagnostic testing services, including complete antimicrobial susceptibility testing, to veterinary clinics, hospitals, and livestock producers. The significance of these labs to the growth of the AST market is based on the high number of analysed samples that are handled by such labs and complex and expensive automatised AST instruments which may not be available to individual clinics.

Veterinary research institutes help to develop the market through validation of new approaches to AST, developing best practices, and education of new generations of veterinary professionals on the value and use of susceptibility testing with the creation of a culture of appropriate use of antimicrobials to which the whole of the market is built.

Regional Analysis

To gain extensive insights into the market, Download for Customization

Based on region, the Veterinary Antimicrobial Susceptibility Testing market has been studied across North America, Europe, Asia Pacific, Latin America, and the Middle East & Africa.

There are some critical issues which are propelling North America to have a leading place in the veterinary AST market. The area has a very developed, well-organized veterinary health care system and several modern veterinary clinics, hospitals and reference laboratories which can easily implement the latest diagnostic technology and automated AST systems as well. We have a gradual conclusion towards accountable antimicrobial dispensation, and there is a growing consciousness of and ahead of antimicrobial effectivity (AMR) in both friends and food-creating animals.

• According to U.S. Animal and Plant Health Inspection Service, 118 veterinary labs are conducting AST in U.S.
• According to U.S. Food and Drug Administration, 14 FDA-approved AST kits for veterinary are used in U.S.

Europe is a developed and a highly regulated veterinary AST market. The regulation has certain provisions on how the antimicrobials in animals must be used prudently and responsibly, even going to the extent of setting aside some key antimicrobials to be used by humans. Part of the legal frameworks are so strong, added to the initiative of programmes such as the European Surveillance of Veterinary Antimicrobial Consumption (ESVAC) project, which has now become obligatory when data are to be collected on sales and use of antimicrobials, directly contributes to the need of AST.

Asia Pacific is emerging fast as a major growth driver of the veterinary AST market. Such a rapid increase is largely driven by the livestock industry growing to satisfy the increasing demand for animal protein due to a growing and large population, especially in regions such as China and India. The use of antibiotics in livestock in certain areas in the region has historically been high, and this results in a heavy burden of AMR.
