Animal Antibiotics and Antimicrobials Market Size, Share, Growth, Trends, and Global Industry Analysis: By Type (Large Volume Infusion Pumps and Syringe Infusion Pumps), By Animal Type (Livestock Animal and Companion Animal), By Distribution Channel (Veterinary Clinics, Online Pharmacies, Retail Pharmacies, and Veterinary Hospitals) and Region Forecast 2020-2031

Animal Antibiotics and Antimicrobials Market size was valued at US$ 6,407.5 million in 2024 and is expected to reach US$ 8,263.1 million by 2031, growing at a significant CAGR of 3.7% from 2025-2031. Moreover, the U.S. Animal Antibiotics and Antimicrobials Market is projected to grow significantly, reaching an estimated value of US$ 2,578.1 Million by 2031.

The animal antibiotics and antimicrobials are medicines used to prevent, treat, and control bacterial infections in animals, playing a crucial role in ensuring the health and productivity of livestock, as well as the well-being of companion animals. The market is primarily driven by the rising global demand for animal-derived food products such as meat, milk, and eggs. This demand is pushing intensive livestock farming, where antibiotics are extensively used to ensure animal health and productivity. As livestock contribute over 33% of global protein consumption, antibiotic use is projected to rise by 67% from 2010 to 2030. A key trend shaping the market is the shift toward antibiotic stewardship programs, promoting responsible use based on accurate diagnosis, proper dosage, and treatment duration. Increased consumer awareness and global advocacy from bodies like the WHO and FAO support this movement.

The opportunity lies in developing next-generation targeted antimicrobial therapies, such as bacteriophages and gene-edited drugs, that reduce AMR risks while offering precision treatment. Growth potential also exists in emerging markets and through digital antibiotic-use monitoring tools. However, a major restraint is the growing threat of antimicrobial resistance due to misuse, regulatory actions, such as antibiotic bans in animal growth promotion, and rising consumer preference for antibiotic-free products.

Facts & Figures

• Rising Demand for Animal-Derived Protein: Global consumption of meat, milk, and eggs continues to surge, especially in developing nations, which directly increases antibiotic use in livestock to maintain herd health and productivity. A landmark study projects antibiotic usage in livestock growing by 67% between 2010 and 2030, from ~63,000?tons to ~106,000?tons, to support this demand.
• Preventive & Prophylactic Antibiotic Usage: Intensive farming practices, driven by the need to maximize yield, rely heavily on metaphylactic and preventive antibiotic use. This helps control disease outbreaks in high-density animal populations, ensuring stable production and market reliability.
• Geographic Expansion of Intensive Farming: Rapid agricultural intensification in regions like Brazil, China, India, Russia, and South Africa is further boosting antibiotic consumption. These emerging markets are scaling up their livestock sectors, which correlates with increased antimicrobial deployment.
• Regulatory Push Enhancing Market Transparency: The stewardship policies and growth-promoter bans are constraining misuse but they also create new opportunities. Demand is growing for veterinary diagnostics, narrow-spectrum antibiotics, and alternatives like vaccines and probiotics. Companies introducing stewardship programs and farm-level surveillance tools are gaining market advantage.

Key Developments:

• In May 2024, Bayer introduced a probiotic-based feed supplement aimed at improving gut health and reducing antibiotic dependency in poultry. Early trial results show improved weight gain and reduced disease, which may expand adoption.
• In March 2025, Merck launched a pilot program to explore bacteriophage treatments targeting specific livestock pathogens. This aligns with growing demand for narrow-spectrum, resistance-free alternatives. If successful, it could significantly alter antibiotic use in the sector.
• In March 2025, through a joint venture, Innovacyn and Elanco are testing a new platform that tracks antibiotic usage and resistance patterns at the farm level using IoT sensors and AI analytics. This strengthens stewardship and opens the door to precision antimicrobials

Animal Antibiotics and Antimicrobials Market Segmentation:

Based on the Type:

• Large Volume Infusion Pumps
• Syringe Infusion Pumps

Large volume infusion pumps held largest market share due to the growing usage of high-volume infusion pumps for administering nourishment parenterally and in emergency situations, as well as for giving fluids to animals during blood transfusions, this segment of the global market dominated in 2021. Nonetheless, throughout the course of the projection period, the syringe infusion pumps sector is anticipated to rise at the greatest CAGR. This is explained by the increased use of syringe infusion pumps as a result of their technological developments.

Based on the animal type:

• Livestock Animal
• Companion Animal

The livestock animal segment holds the highest market share in the market. This dominance is largely driven by high-volume antibiotic use in food-producing species, particularly poultry, swine, and cattle, to prevent disease, support growth, and maintain herd health in intensive farming systems. Recent global data shows that roughly 73% of all antibiotics used for antimicrobial purposes are administered in livestock operations.

In contrast, the companion animal segment, covering pets like dogs and cats, represents a significantly smaller share. Pets require lower total doses, and their treatments are often managed on a case-by-case basis, rather than the routine, herd-level administration common in livestock.

Based on the distribution channel:

• Veterinary Clinics
• Online Pharmacies
• Retail Pharmacies
• Veterinary Hospitals

The veterinary hospitals segment holds the highest market share in the animal antibiotic and antimicrobial market by distribution channel. Veterinary hospitals are equipped with advanced diagnostic tools and surgical facilities, making them the preferred choice for comprehensive animal healthcare, especially for serious infections and post-operative antibiotic treatments. These hospitals typically maintain a full stock of a wide range of antibiotics and are staffed by trained veterinarians, enabling accurate prescriptions and proper dosage administration. Their role in both preventive and curative care across livestock and companion animals significantly drives sales through this channel.

Online Pharmacies account for a smaller market share due to limited product access, regulatory constraints in several countries, and the preference for in-person veterinary consultations before purchasing antibiotics.
