Livestock Dewormers Market Size and Share

Livestock Dewormers Market Analysis by Âé¶¹ÊÓÆµ
Livestock Dewormers Market size in 2026 is estimated at USD 8.57 billion, growing from 2025 value of USD 8.18 billion with 2031 projections showing USD 10.82 billion, growing at 4.78% CAGR over 2026-2031.
COVID-19 had a significant impact on the livestock dewormers market since routine deworming activities were delayed or canceled due to the unavailability of veterinary doctors around the globe. The American Veterinary Medical Association reported that in September 2021, due to COVID-19, veterinary clinics had a challenging 18+ months, and many veterinarians were forced to adapt to the changes it caused. In the early months of the outbreak, veterinary clinics only received urgent cases because they were operating as required businesses. This significantly impacted the livestock dewormers market. However, as the restrictions were lifted, the livestock dewormers market bounced back and is expected to witness growth in the coming years due to an increase in parasitic diseases in livestock animals.
The rise in demand for animal-based food products, including animal meat and milk, all across the globe is expected to fuel the market growth, owing to the direct association of animal meat and milk consumption with the demand for treatment and cure of any animal disease. For instance, according to Eurostat, the annual meat production, such as bovine, poultry, pigs, and sheep, has constantly been increasing in the European market. European Union pork production grew in the first five months of 2021, according to data from the European Union Commission. The European Union produced 1.88 million tonnes of pork in May, down 1% from April but up 5% (96,600 tonnes) year-on-year. 19.87 million clean pigs were slaughtered during the month, 5% (949,500 head) more than a year ago. This is due to the growing demand for protein-rich food, primarily driven by the rise in health consciousness among consumers, globally.
Parasitic diseases are quite common in animals around the world. For instance, as per an article published in June 2022 in Hindawi, helminthic infections were still present in the animals despite the widespread use of broad-spectrum antiparasitic medications by farmers in recent years. This circumstance demonstrated the farmers' failure to effectively implement helminthic infection management programs. Such studies throw light on the need to provide proper education to farmers and thereby increase the demand for dewormers across the globe.
While the market looks to develop, side effects associated with dewormers are expected to restrain the market growth.

Global Livestock Dewormers Market Trends and Insights
The Cattle Segment is Expected to Show Better Growth Over the Forecast Years
The growth of the cattle segment is mainly attributed to the high population of cattle across the world and the dominance of cattle farming as a major income source for people in many countries. For instance, as per the Livestock and Products Semi-annual - 2022 by USDA, FAS New Delhi (Post) estimated the total cattle stock number to be 306.9 million head, as compared to 305.5 million heads in 2021.
Furthermore, per the Central Statistics Office Ireland Crops and Livestock, the total cattle numbers were up by 37,300 from 2021 to 7,396,200 in 2022.
Moreover, research studies involving cattle deworming are expected to boost segment growth. As per an article published in October 2022 in PubMed, only the concurrent application of both eprinomectin and oxfendazole was effective at reducing fecal egg counts in beef cattle. The simultaneous use of anthelmintics is extremely effective and prevents resistance, according to model simulations and experiments on live animals.

North America is Anticipated to Hold a Significant Market Share in the Livestock Dewormers Market Over the Forecast Period
North America is among the major contributors to livestock and the implementation of animal healthcare benefits across the globe. The market is growing rapidly due to the increasing prevalence of livestock worm infection and the rise in veterinary disease awareness programs coupled with the growing demand for animal products. For instance, in October 2022, the Canadian Veterinary Medical Association (CVMA) conducted an annual national public awareness campaign named 'Animal Health Week (AHW)' hosted by veterinarians across Canada. Each year, through AHW, the veterinary community draws attention to an important health-related message. The 2022 campaign's theme displayed how Canada's veterinary professionals occupy unique positions within the national One Health community in protecting animal health which, in turn, protects everyone's health.
Furthermore, per the USDA update published in August 2022, USDA projects poultry imports to grow to 17.5 million metric tons by 2031. In comparison, pork imports are projected to increase to 14.8 million metric tons by 2031, and beef imports are expected to rise to 14.3 million metric tons. With such an increase in poultry and livestock businesses, demand for deworming livestock also rises and thereby boosting the market growth over the forecast period.
Moreover, as per the USDA Livestock and Products semi-annual report published in March 2021, Mexico's pig crop for 2021 stands at 20.8 million heads and calf crop was projected at 8.16 million heads in 2021. Such a rise in livestock food production demands proper deworming and thereby drives the market growth over the forecast period.

Market Opportunities and Future Outlook
Product and program activity tied to emerging parasite threats and resistance management is creating room for differentiated livestock dewormer portfolios and supporting tools. In the United States, New World screwworm preparedness has driven time-bound regulatory actions and product positioning, including FDA emergency use authorizations for ivermectin-based solutions (for example, Boehringer Ingelheim IVOMEC 1% Injection) and conditional/expanded approvals for targeted parasite control products (for example, Zoetis Dectomax-CA1 vial-size additions). These actions support faster demand for rapid-deployment SKUs, flexible dosing formats, and field guidance that fits different cattle processing practices.
Non-chemical and integrated parasite management approaches are also creating commercialization pathways alongside conventional anthelmintics. In the European Union, Regulation (EU) 2026/534 authorized the nematophagous fungus Duddingtonia flagrans (NCIMB 30336) as a feed additive for grazing livestock, reinforcing interest in adjunct solutions that reduce parasite burden while addressing resistance and environmental scrutiny. Separately, the US FDA issued Guidance for Industry GFI #95 (VICH GL12) on June 24, 2026, which sets harmonized effectiveness testing recommendations for bovine anthelmintics and supports more standardized development and evidentiary pathways for established and new entrants, including bioequivalent generics such as Norbrook Defendazole (fenbendazole) approved as a bioequivalent alternative to Safe-Guard.
Recent Industry Developments
- June 2026: Zoetis shared updated resources and management tips for livestock producers responding to New World screwworm, reiterating the availability of Dectomax-CA1 for New World screwworm larvae in cattle. The expanded producer guidance supports faster on-farm implementation and reinforces the company's role in emergency parasite response protocols.
- May 2026: Zoetis announced that a 100 mL vial size of Dectomax-CA1 (doramectin injection) received conditional FDA approval for the prevention and treatment of New World screwworm larvae in cattle, complementing previously available larger vial sizes. The added presentation improves fit with different herd sizes and purchasing patterns, supporting broader adoption in outbreak-management settings.
- February 2026: Boehringer Ingelheim secured an FDA Emergency Use Authorization for IVOMEC (ivermectin) 1% Injection to help protect cattle against New World screwworm. The authorization shows how emergency regulatory pathways can quickly expand use cases for established endectocides when new or resurging parasite threats emerge.

Data Sources, Market Sizing, and Validation
Desk Research
Desk work starts by building the demand pool by species and region, and then mapping it to how dewormers are typically purchased and used on farms. Public data points anchor the model, especially where farm structure and climate drive different treatment patterns.
We referred to sources such as FAOSTAT for livestock population and production indicators, WOAH resources for animal health and disease context, USDA and Eurostat livestock and trade statistics, and releases from national agriculture ministries when herd counts and veterinary program notes are published. We also used peer-reviewed parasitology and veterinary science papers to understand resistance trends and typical treatment frequencies. Company annual filings, investor decks, and reputable press were used to cross-check category growth statements and channel direction, and selected paid subscriptions were used for company financials, news screening, and patent lookups where needed. This list is indicative only, since many other sources were used during data collection, validation, and clarification.
Primary Interviews and Surveys
Primary work focused on tightening assumptions for how dewormers are prescribed, bundled, and priced across key livestock species, and how seasonality affects ordering patterns. We spoke with manufacturers and distributors, livestock veterinarians, and large farm operators across major consuming regions, so treatment rates, channel splits, and price ranges could be refined before finalizing the model.
Distribution of primary research fieldwork respondents
| Company type | Respondent position | Region |
|---|---|---|
| Top tier: 31% | CXOs: 14% | APAC: 48% |
| Mid tier: 52% | Functional/Unit leaders: 27% | EMEA: 32% |
| Smaller Players: 17% | Managers: 59% | Americas: 20% |
Market-Sizing & Forecasting
Our sizing logic is built top-down by reconstructing country-level demand from livestock populations and production systems, then applying practical treatment and purchasing assumptions for internal parasite control. Since dewormer usage is not consistent across cattle, swine, and poultry, the model uses species mix and farm intensity to adjust treatment frequency and the share of animals covered.
To keep the output realistic, we corroborate it with selective bottom-up approximations, such as supplier and channel checks, sampled average selling prices by route of administration, and volume signals inferred from packaging mix. When gaps appear in smaller countries, we use proxy relationships based on similar farming systems and climate exposure, and then re-check the implied per-animal spend with interview feedback.
Forecasts use scenario analysis supported by short-cycle indicators. Typical inputs include livestock headcount trends, feed cost pressure (which influences preventive spend), parasite resistance awareness, shifts toward oral versus topical formats, and local regulatory actions affecting veterinary medicines. Assumptions are reviewed with practitioners so adoption and pricing paths align with what farms are likely to do, rather than what would be ideal on paper.
Data Validation & Update Cycle
Validation is done through multiple checks so the final number stays consistent with observable market signals. We compare modeled revenues against independent indicators such as livestock population movements, veterinary medicine category growth cues, and regional purchasing seasonality, then investigate outliers before sign-off.
We apply a second analyst review to key assumptions like treatment rate, average price range, and currency conversion timing. If variances are large, follow-up calls are made with respondents. Reports are refreshed annually, and interim updates are made when material events occur, such as regulatory changes or sharp swings in farm economics. Before delivery, the model and key tables are rechecked so the latest view is provided.
Âé¶¹ÊÓÆµ's Livestock Dewormers Market Size Versus Other Published Estimates
Published market sizes for livestock dewormers can differ even when they appear to cover the same space, since boundaries and counting logic are not always aligned. The spread typically comes from which animal categories are included, which sales channels are counted, and how currency and pricing are handled in the base year.
By tracking treatment frequency by species and route of administration, then refreshing currency timing and price ranges with field feedback, Âé¶¹ÊÓÆµ keeps the estimate tied to the actually treated livestock pool rather than a broader animal health spend bucket. Some publishers fold in wider parasiticide categories, while others use uniform per-animal spend assumptions across regions with different farm intensity and seasonality.
Benchmark comparison
| Source | Market Size | Gaps in Research Methodology |
|---|---|---|
| Âé¶¹ÊÓÆµ | USD 8.57 B (2026) | |
| Global Consultancy A | USD 8.38 B (2025) | Uses an earlier base year and may apply a broader or different channel boundary, which can shift totals when distributor margins and on-farm procurement timing are treated differently. |
| Industry Publisher B | USD 7.90 B (2024) | Anchors the market on a 2024 base and can understate value if average price progression is kept flat across species, or if only select product classes and geographies are counted. |
The table shows that even a one to two year base shift can create visible gaps once price movement and exchange rates are applied. When scope is kept specific to livestock deworming use and assumptions are rechecked against species level usage patterns, the final market size is easier to trace and repeat year after year.
