What Is an Ungulate? A Guide to Hoofed Mammals

Ungulates are mammals that carry their body weight on the tips of their toes, which are covered by hooves. This limb structure distinguishes them from other mammals that walk on flat feet or on their toes without hooves. The group includes familiar farm animals such as cattle, sheep, goats, pigs, horses, and donkeys, as well as wild species such as deer, elk, moose, bison, camels, giraffes, zebras, rhinos, and tapirs. Ungulates are not a single evolutionary branch but a functional category defined by shared adaptations for running and weight support. Most ungulates are herbivores, and their digestive systems, social behavior, and ecological roles reflect that plant-based diet. This article explains what makes an animal an ungulate, how the major groups are classified, and why these animals matter in farming, wildlife management, and public health.

Defining Features of Ungulates

The word ungulate comes from the Latin ungula, meaning hoof or claw. A hoof is a thickened, keratinized structure that covers the distal phalanx, the last bone of the toe. Hooves are a form of modified nail that protects the toe tip and provides a hard surface for locomotion. In practical terms, a hoofed mammal is one whose toes end in hooves instead of claws, nails, or fleshy pads.

Limb Structure and Locomotion

Ungulates are adapted for running and long-distance travel. Their legs are elongated, and the bones of the lower limb are often fused to create a stable column. The weight-bearing axis passes through the middle toes, and the number of functional toes varies between groups. This arrangement reduces the surface area in contact with the ground, which increases speed but reduces stability on soft or uneven terrain. Farmers observe this tradeoff when cattle or horses struggle on muddy ground or icy surfaces, where the small hoof surface provides less traction than a padded foot.

The limb structure of ungulates also affects how they rest and rise. Many ungulates can lock their limbs in a standing position for long periods, a feature that helps them flee predators quickly. Horses can sleep standing up because of a locking mechanism in their forelimbs. Cattle and sheep also rest standing for long periods, though they do lie down for rumination and deep sleep.

Digestive Adaptations

Most ungulates are herbivores, and their digestive systems are specialized for breaking down plant material. Plant cell walls contain cellulose, which requires microbial fermentation to digest. Ungulates handle this challenge in two main ways. Ruminants, such as cattle, sheep, goats, deer, and giraffes, have a four-chambered stomach that ferments food before it enters the true stomach. Non-ruminant herbivores, such as horses, rhinos, and tapirs, ferment plant material in an enlarged cecum and colon after the stomach. Pigs are omnivorous and have a simpler stomach, but they still consume substantial plant material.

These digestive differences matter for management. Ruminants can extract more energy from fibrous forage than horses can, but they are more sensitive to sudden changes in diet because their rumen microbial populations need time to adjust. Horses can process smaller meals more frequently but are prone to digestive upset if they eat large amounts of grain at once. A farmer who understands these differences can make better decisions about feeding schedules, forage quality, and pasture rotation.

Social Behavior and Group Living

Many ungulates are social animals that live in groups. Group living offers protection from predators, improves detection of threats, and can increase foraging efficiency. However, the definition of a group varies widely across species and studies. A review of group size estimation in ungulates found that researchers defined groups using nearest neighbor distances ranging from 1.4 meters to 1,000 meters, and temporal windows ranging from three minutes to 24 hours. This variability complicates comparisons between studies and can affect ecological conclusions. For practical purposes, a farmer or wildlife manager should define group size clearly and consistently when recording observations, because the same animals may appear solitary or social depending on the spatial and temporal scale used.

Social learning in ungulates is an area of active research. Horses, for example, can acquire new behaviors by observing other horses, but the mechanisms range from simple social facilitation to genuine learning by observation. A review of social learning in horses noted that assuming higher mental abilities in the absence of evidence can have welfare implications, such as isolating stereotypical horses on the assumption that stereotypic behaviors can be learned by watching neighbors. Farmers should be cautious about attributing complex cognitive abilities to ungulates without supporting evidence, and should base management decisions on observed behavior instead of assumptions about learning.

At a Glance: Major Ungulate Groups

Classification of Hoofed Mammals

The traditional classification of ungulates divides them into two main orders based on toe number. Perissodactyls have an odd number of toes, and artiodactyls have an even number. This simple distinction has been refined by molecular phylogenetics, which has revealed that some animals traditionally classified as ungulates are more closely related to other groups. Whales, dolphins, and porpoises evolved from even-toed ungulates, and they are now classified within the artiodactyl lineage. This means that the term ungulate is a functional description instead of a precise evolutionary grouping.

Odd-Toed Ungulates: Perissodactyla

Perissodactyls include horses, donkeys, zebras, tapirs, and rhinos. These animals bear most of their weight on the middle toe, which is the largest. Horses and their relatives have a single functional toe on each foot, while rhinos have three toes and tapirs have four toes on the front feet and three on the hind feet. Perissodactyls are hindgut fermenters, meaning they digest fiber in the cecum and colon instead of in a multi-chambered stomach.

The evolutionary history of perissodactyls is complex. A phylogenetic analysis that included the extinct South American litopterns found that these animals nested as successive stem-clades of crown Perissodactyla. This finding suggests that southern continents played an important role in the early evolution of hoofed mammals. The same study indicated that litopterns were not closely related to any North American basal ungulate, which challenges earlier hypotheses about the origins of South American hoofed mammals.

Tapirs are notable among perissodactyls for their short proboscis, a flexible snout used for grasping leaves. A comparative study of cranial characters in tapirs and other hoofed mammals found that the core features of the proboscis develop prenatally, while complementary features develop after birth. The study suggested that some fossil taxa may have possessed a true short proboscis, and that the proboscis evolved convergently in hoofed mammals through a terminal addition sequence of character evolution.

Even-Toed Ungulates: Artiodactyla

Artiodactyls include cattle, sheep, goats, pigs, deer, elk, moose, camels, giraffes, and hippos. These animals bear weight on two toes, the third and fourth digits, which are enlarged and symmetrical. The other toes are reduced or absent. Artiodactyls are the most diverse and widespread group of large herbivores, and they include both ruminants and non-ruminants.

Ruminant artiodactyls have a four-chambered stomach that allows them to ferment plant material before digestion. This system enables them to extract more energy from fibrous forage than hindgut fermenters can. The ruminant digestive system also produces methane as a byproduct of fermentation, which has implications for greenhouse gas emissions from livestock production.

Non-ruminant artiodactyls, such as pigs and peccaries, have a simpler stomach but can still digest substantial amounts of plant material. Pigs are omnivorous and consume a wide range of foods, including roots, tubers, fruits, insects, and small animals. Hippos are also artiodactyls, and they are adapted for a semi-aquatic lifestyle.

Cranial Appendages: Horns and Antlers

Many ruminant artiodactyls possess cranial appendages, either horns or antlers. Horns are permanent structures with a bony core covered by keratin, and they are found in cattle, sheep, goats, and antelope. Antlers are temporary structures that are shed and regrown annually, and they are found in deer, elk, and moose. A gene expression study comparing juvenile cattle horn buds to growing deer antler tissues found patterns that support homology of horns and antlers relative to a cranial-appendage-lacking outgroup. The study also identified gene expression patterns that could support a shared cranial neural crest origin for horns and antlers. This research has implications for understanding the evolutionary origins of these structures and for breeding decisions in livestock.

Extinct Ungulate Lineages

The fossil record contains many ungulate lineages that no longer exist. Litopterns were endemic South American ungulates that ranged from the Paleocene to the late Pleistocene. They had unique anatomy, including a horse-like limb structure in some species, but their phylogenetic affinities were uncertain for over a century. Recent molecular and morphological analyses have placed litopterns within the perissodactyl lineage, as successive stem-clades of crown Perissodactyla. This finding highlights the complex early history of hoofed mammals and the importance of southern continents in their evolution.

Evolutionary Significance of Ungulates

Ungulates have played a central role in the evolution of terrestrial ecosystems. As large herbivores, they shape vegetation structure, influence nutrient cycling, and provide prey for carnivores. Their digestive adaptations have allowed them to exploit fibrous plant material that other mammals cannot digest, and their limb adaptations have enabled them to travel long distances in search of food and water.

Ecological Roles

Ungulates affect plant communities through grazing and browsing. Grazing removes grass and other low-growing vegetation, while browsing removes leaves and twigs from trees and shrubs. The intensity of ungulate herbivory can determine whether a landscape remains grassland, shrubland, or forest. A study of oak regeneration in early successional woodlands grazed by wild ungulates in the absence of livestock found that browsing can block the regeneration of preferred tree species. The study monitored tree regeneration and browsing from 2012 to 2024 in permanent plots in De Hoge Veluwe National Park in the Netherlands. Tree species preferred by ungulates had less height growth when subject to browsing, and exclusion of ungulates led to a substantial increase in height growth of preferred species. The authors concluded that attempts to diversify these forests and increase resilience to climate change cannot succeed under current ungulate densities.

Ungulates also disperse seeds through their feces. A study of herbaceous seed dispersal by ungulates in grasslands of Doñana National Park in southwestern Spain found that a mixed community of four ungulate species dispersed more seeds than a community used almost exclusively by deer. The study collected and georeferenced ungulate fecal samples from early spring to mid-summer and identified the seeds contained in the samples. Within the four-species community, cattle and deer differed most in the taxonomic composition of the seeds they dispersed, suggesting that herbivore-specific seed selection and dispersal act as key drivers of grassland structure at fine spatial scales.

Effects of Environmental Stress

Ungulate populations are sensitive to environmental conditions, particularly winter weather. A study of bighorn sheep at Ram Mountain in Alberta, Canada, used 45 years of individual-based data to evaluate how snow cover duration, depth, and density affect spring body mass, reproduction probability, and subsequent autumn body mass. The study found that long and deep snow covers reduced spring body mass across all demographic groups, with yearling males losing up to 0.12 kg per additional centimeter of snow depth. Harsh snow conditions reduced the probability of reproduction for adult females and generated a compensatory indirect effect on mass by avoiding the energetic costs of reproduction. Yearlings showed no compensatory responses and entered the following autumn in poor condition, up to 14% lighter for males and 8% for females following the deepest snow years. These findings demonstrate that distinct demographic groups rely on different mechanisms to cope with environmental constraints, and that the effects of snow conditions generate persistent, context-dependent carry-over effects across seasons.

Parasites and Disease

Ungulates serve as hosts for a wide range of parasites and pathogens. A survey of intestinal parasites in zoo animals in Ljubljana, Slovenia, found that ungulates were the most infected group, with parasites detected in 61% of samples. The study collected 741 fecal samples from 40 animal species over eight years and found helminths in 25% of samples and protists in 13% of samples. The authors recommended routine monitoring of parasitic infection and regular deworming and hygienic measures to prevent gastrointestinal infections in captive animals.

Ungulates are also intermediate hosts for Echinococcus species, the tapeworms that cause cystic echinococcosis. The parasite requires two mammalian hosts to complete its life cycle: a definitive host, mainly dogs, harboring the adult parasite in its intestines, and an intermediate host, mostly farm and wild ungulates, where hydatid cysts develop mainly in the liver and lungs. Humans are accidental intermediate hosts, susceptible to infection through ingestion of oncospheres. A review of Echinococcus species in wildlife noted that numerous records of cysts in wild ungulates date back to the 20th century, but cannot with certainty be allocated to the Echinococcus species and genotypes recognized today. The review listed more than 150 species of wild hosts and noted that current knowledge is largely restricted to studies of the past two decades.

Vaccination of intermediate hosts can reduce the prevalence of human echinococcosis. A study of vaccination against Echinococcus granulosus found that immunisation of sheep with oncosphere secretions or with an oncosphere homogenate resulted in 99% resistance to a challenge infection. Immunisation with a specific purified protein resulted in 92% resistance, and immunisation with a fusion protein gave 97% and 98% resistance in two separate trials. The vaccine has the potential to be used as a tool for control of transmission of E. granulosus through its natural intermediate hosts, particularly domestic ungulates, as part of hydatid control programs.

Ungulates can also serve as sentinel animals for disease surveillance. A study in South Korea found that the seroprevalence of Japanese encephalitis virus in deer and elk fawns increased from 2.4% in 2008 to 24.1% in 2009, and in wild boars it increased from 19.3% to 55.0% in the same period, which preceded a surge of human cases. The seroprevalence in calves increased from 15.3% in 2008 to 35.8% in 2010, and that in lambs and goat kids increased from 8.5% in 2009 to 26.2% in 2010, which coincided with the surge in humans. The authors concluded that surveillance of sentinel animals may be useful to predict emergence of Japanese encephalitis in humans.

Ungulates in Farming and Wildlife Management

Ungulates are among the most economically important animals in the world. Domesticated species provide meat, milk, wool, leather, and labor, while wild species support hunting, tourism, and ecosystem services. Managing ungulates requires an understanding of their biology, behavior, and ecological requirements.

Livestock Management

Farmers manage ungulates for production, health, and welfare. Key management decisions include breed selection, feeding, housing, breeding, and disease prevention. Each species has specific requirements that reflect its evolutionary history and digestive physiology.

Ruminants require a diet that supports rumen function. Sudden changes in feed can disrupt the rumen microbial population and cause digestive upset, including bloat and acidosis. Farmers should introduce new feeds gradually over several days to allow the rumen to adapt. Hindgut fermenters, such as horses, are more tolerant of dietary changes but are prone to colic and laminitis if they consume large amounts of grain. Farmers should provide horses with frequent small meals and limit grain intake.

Parasite control is a major component of ungulate health management. Grazing animals are exposed to internal parasites through contaminated pasture, and the intensity of infection can affect growth, reproduction, and survival. A review of ungulate helminth transmission identified six transmission routes and found that ungulate helminth parasitism has evolved some 25 times. The review noted that direct egg transmission to ungulates is rare, and suggested that this is due to a transmission barrier caused by ungulate faecal avoidance. Farmers can reduce parasite burdens by rotating pastures, avoiding overgrazing, and using targeted deworming based on fecal egg counts.

Wildlife Management

Wild ungulates are managed for conservation, hunting, and ecosystem health. Management objectives can conflict, as illustrated by the management of moose in Alaska. The State of Alaska has a long history of controlling predators to enhance ungulate populations, including moose. The Alaska Board of Game establishes regulations promoting the harvest of moose and other ungulates for human consumption, typically by controlling bears and gray wolves. However, a review of moose population dynamics argued that current management does not encompass a full range of management options and fails to consider important aspects of population dynamics. Predators maintain some moose populations at a low density, reducing the harvest of moose but promoting large-antlered individuals, which are of value to the professional guide and tourism industries. The review argued that if the proximity of the moose population to ecological carrying capacity is known, management strategies that increase the human harvest of moose and also promote trophy antlers may be possible.

Winter feeding is a common intervention for wild ungulates in regions with harsh winters. A study of fallow lands in the Kirzinsky State Nature Reserve in Western Siberia found that fallow lands can serve as a basis for the formation of a perennial feeding platform to support wild ungulates during abnormal periods of the winter cycle. The use of fallow lands contributed to an increase in the number of Siberian roe deer by almost three times with the use of biotechnical measures. Another study found that clearing snow from forage fields during the snowy season is an effective method of feeding wintering fauna, especially for Siberian roe deer. By clearing snow from winter pastures where biotech crops and grasses such as sunflowers, oats, peas, and alfalfa were sown, large roe deer groups can be provided with a good and balanced forage ration.

Insect Harassment and Its Effects

Insects can have significant impacts on ungulate behavior and physiology. A study of the impacts of hematophagous and endoparasitic insects on caribou in the Arctic found that caribou increase their movements during peak insect harassment, evading and running away from these parasites. These behavioral responses scale up to physiological effects as caribou move to less productive habitats to reduce harassment, which increases energetic costs due to locomotion, reduces nutrient intake due to less time spent foraging, and can lead to poorer physiological condition. Reduced physiological condition can lead to lower reproductive output and even higher mortality rates, with the potential to ultimately affect caribou demographics. The study noted that mosquitoes meet the criteria for venomous, and that warble flies satisfy the definition for toxungenous, broadening the definitions of venomous and toxungenous animals to include hematophagous and endoparasitic insects.

Practical Assessment Steps for Identifying Ungulates

Identifying whether an animal is an ungulate requires observation of several key features. The following steps provide a practical approach for students, researchers, and professionals.

Step 1: Examine the Feet

Look at the animal's feet and count the toes. If the toes end in hooves, the animal is an ungulate. Count the number of functional toes on each foot. Odd-toed ungulates have one or three toes, while even-toed ungulates have two or four toes. Note that some ungulates, such as camels, have soft pads instead of hard hooves, but they still bear weight on their toes.

Step 2: Observe the Teeth

Ungulates have specialized teeth for processing plant material. Ruminants have a dental pad on the upper jaw instead of upper incisors, and they grind food with their molars. Horses have both upper and lower incisors and continuously erupting molars. Pigs have omnivorous dentition with prominent canines. Examining the teeth can help distinguish between ungulate groups.

Step 3: Assess the Digestive System

If the animal is a ruminant, it will chew cud, which is regurgitated plant material. Ruminants spend a significant portion of their day ruminating, and farmers can observe this behavior to confirm that an animal is a ruminant. Non-ruminant ungulates do not chew cud, and they process fiber in the hindgut.

Step 4: Consider the Habitat and Behavior

Ungulates are found in a wide range of habitats, from grasslands and savannas to forests, tundra, and deserts. Their social behavior varies by species, with some forming large herds and others living solitarily or in small family groups. Observing the animal's habitat and behavior can provide clues to its identity and ecological role.

Step 5: Record Observations Systematically

When recording observations of ungulates, define the spatial and temporal scale clearly. A review of group size estimation in ungulates recommended that researchers clearly describe the spatiotemporal extents over which they define ungulate group sizes, highlight foundational empirical and ecological rationale for these extents, and seek to align such extents among individual species to facilitate cross-system comparisons. These recommendations apply to any observer recording ungulate behavior, whether in a research setting or on a farm.

Records and Measurements for Ungulate Management

Keeping accurate records is essential for effective ungulate management. The following measurements are commonly used to monitor health, growth, and reproduction.

Body Weight and Condition

Body weight is a fundamental measure of ungulate health and productivity. Weighing animals regularly can detect changes in condition that may indicate disease, nutritional stress, or management problems. Body condition scoring provides a visual assessment of fat and muscle reserves and is a practical alternative to weighing when scales are not available.

Reproductive Records

Reproductive performance is a key indicator of herd health. Records should include breeding dates, calving or lambing dates, number of offspring, and weaning weights. These records can identify problems such as low conception rates, high neonatal mortality, or poor maternal nutrition.

Health Records

Health records should document vaccinations, deworming treatments, disease diagnoses, and treatments. These records are essential for regulatory compliance and for tracking the effectiveness of health management programs. They also provide a basis for professional consultation when problems arise.

Behavioral Observations

Behavioral observations can provide early warning of health and welfare problems. Changes in feeding behavior, social interactions, or activity patterns may indicate pain, illness, or stress. Farmers should record behavioral observations systematically and investigate any significant changes.

Common Failure Patterns in Ungulate Management

Several common problems can undermine ungulate health and productivity. Recognizing these patterns early can prevent serious losses.

Nutritional Failure

Nutritional failure occurs when animals do not receive adequate energy, protein, minerals, or vitamins. Symptoms include poor growth, low body condition, reduced reproductive performance, and increased susceptibility to disease. Nutritional failure can result from inadequate feed quality, insufficient feed quantity, or improper feed formulation. Farmers should monitor body condition regularly and adjust feeding programs based on observed changes.

Parasite Overload

Parasite overload occurs when animals are exposed to more parasites than their immune systems can control. Symptoms include weight loss, diarrhea, anemia, and poor coat condition. Parasite overload is more common in overgrazed pastures and in animals that have not developed immunity. Farmers should implement integrated parasite control programs that include pasture rotation, fecal egg count monitoring, and targeted deworming.

Disease Outbreaks

Disease outbreaks can cause rapid and severe losses in ungulate populations. Common diseases include respiratory infections, digestive disorders, and reproductive diseases. Outbreaks are more likely in crowded conditions, in animals with poor nutrition, and in herds with inadequate biosecurity. Farmers should implement biosecurity measures to prevent disease introduction and spread, and should consult a veterinarian promptly when disease is suspected.

Environmental Stress

Environmental stress can reduce ungulate health and productivity. Heat stress, cold stress, and snow conditions can all affect feed intake, growth, and reproduction. A study of bighorn sheep found that harsh snow conditions reduced spring body mass across all demographic groups and reduced the probability of reproduction for adult females. Farmers and wildlife managers should monitor environmental conditions and provide shelter, supplemental feed, or other interventions when conditions are severe.

Welfare and Safety Context

Ungulate welfare is a growing concern for farmers, consumers, and regulators. Welfare issues can arise from inadequate nutrition, poor housing, painful procedures, and stressful handling. Farmers should provide for the basic needs of their animals, including adequate food and water, shelter from extreme weather, space to move and rest, and protection from injury and disease.

Handling ungulates safely requires an understanding of their behavior and flight zones. Large ungulates, such as cattle and horses, can injure handlers if they are startled or frightened. Farmers should use low-stress handling techniques, maintain facilities in good repair, and train handlers in safe practices.

The use of ungulates in research and education is subject to ethical and regulatory oversight. Researchers should follow institutional guidelines for animal care and use, and should minimize pain and distress in experimental animals. A mouse model of secondary cystic echinococcosis has been developed to study the immunobiology of the disease and to test new chemotherapeutics and vaccine candidates. The model involves two sequential stages: an early stage of parasite pre-encystment and a late or chronic stage of parasite post-encystment. The outcome depends on several factors, including the parasite infective dose, the mouse strain, and the parasite species or genotype.

Professional Escalation Criteria

Some situations require professional consultation. Farmers and managers should seek veterinary advice when they observe signs of disease, injury, or distress that do not respond to routine management. Wildlife managers should consult with biologists or ecologists when making decisions that could affect ungulate populations or their habitats. Researchers should consult with statisticians or methodologists when designing studies or interpreting data.

Specific escalation criteria include:

• Unexplained deaths in a herd or population
• Rapid weight loss or poor body condition despite adequate feed
• Reproductive failure, including low conception rates or high neonatal mortality
• Signs of infectious disease, such as fever, diarrhea, or respiratory distress
• Behavioral changes that suggest pain, fear, or distress
• Parasite burdens that do not respond to treatment
• Environmental conditions that threaten animal survival, such as deep snow or extreme heat

Frequently Asked Questions

What is the difference between odd-toed and even-toed ungulates?

Odd-toed ungulates, classified in the order Perissodactyla, bear most of their weight on the middle toe and have one or three functional toes on each foot. Horses, donkeys, zebras, tapirs, and rhinos are odd-toed ungulates. Even-toed ungulates, classified in the order Artiodactyla, bear weight on two toes, the third and fourth digits, and have two or four functional toes. Cattle, sheep, goats, pigs, deer, elk, moose, camels, and giraffes are even-toed ungulates. The two groups also differ in digestive anatomy, with most even-toed ungulates being ruminants and all odd-toed ungulates being hindgut fermenters.

Are all ungulates herbivores?

Most ungulates are herbivores, but not all. Pigs and peccaries are omnivorous and consume a wide range of foods, including roots, tubers, fruits, insects, and small animals. Hippos are primarily herbivorous but have been observed consuming meat on occasion. The digestive systems of ungulates are adapted for processing plant material, but some species have evolved to exploit animal foods as well.

Are whales considered ungulates?

Whales, dolphins, and porpoises evolved from even-toed ungulates, and they are now classified within the artiodactyl lineage. However, they do not have hooves and are not considered ungulates in the functional sense. The term ungulate is used to describe hoofed mammals, and whales are fully aquatic mammals that have lost their hind limbs and hooves through evolution.

What is the difference between horns and antlers?

Horns are permanent structures with a bony core covered by keratin, and they are found in cattle, sheep, goats, and antelope. Both males and females may have horns, depending on the species. Antlers are temporary structures that are shed and regrown annually, and they are found in deer, elk, and moose. Antlers are typically found only in males, with the exception of caribou, in which both sexes grow antlers. A gene expression study found patterns that support homology of horns and antlers relative to a cranial-appendage-lacking outgroup.

Why do ungulates live in groups?

Group living offers several benefits to ungulates, including protection from predators, improved detection of threats, and increased foraging efficiency. However, the definition of a group varies widely across species and studies. A review of group size estimation in ungulates found that researchers used nearest neighbor distances ranging from 1.4 meters to 1,000 meters and temporal windows ranging from three minutes to 24 hours. This variability complicates comparisons between studies and can affect ecological conclusions.

How do ungulates affect forest regeneration?

Ungulates can block forest regeneration by browsing on tree seedlings and saplings. A study of oak regeneration in early successional woodlands grazed by wild ungulates found that tree species preferred by ungulates had less height growth when subject to browsing, and exclusion of ungulates led to a substantial increase in height growth of preferred species. The study concluded that attempts to diversify forests and increase resilience to climate change cannot succeed under current ungulate densities.

What role do ungulates play in disease transmission?

Ungulates serve as intermediate hosts for Echinococcus species, the tapeworms that cause cystic echinococcosis. The parasite
