Camelus bactrianus Linnaeus, 1758

Taxonomy and Size Classification

The Bactrian camel (Camelus bactrianus Linnaeus, 1758) is the largest mammal in its native range and the largest living camel, though it has a shorter shoulder height than the dromedary.

Shoulder and Overall Height

Its shoulder height ranges from 160 to 180 cm (5.2 to 5.9 ft), with an overall height of 230 to 250 cm (7.5 to 8.2 ft).

Head-and-Body and Tail Length

Head-and-body length measures 225–350 cm (7.38–11.48 ft), and tail length is 35–55 cm (14–22 in).

Hump Height

Average height measured at the top of the humps is 213 cm (6.99 ft).

Body Mass

Body mass ranges from 300 to 1,000 kg (660 to 2,200 lb): males average around 600 kg (1,300 lb), while females average around 480 kg (1,060 lb).

Coat Coloration

This species has a long, wooly coat that varies in color from dark brown to sandy beige.

Neck Hair

A mane and beard of long hair up to 25 cm (9.8 in) long grows on the neck and throat.

Winter Coat Shedding

Its shaggy winter coat is shed extremely quickly, with large sections peeling off all at once, giving the appearance of a sloppy shearing.

Hump Composition

The two humps on its back are made up of fat, contrary to the common misconception that they store water.

Facial Structure

Its face follows the typical camelid shape: long and somewhat triangular, with a split upper lip.

Sandstorm Adaptations

Long eyelashes and sealable nostrils work together to block dust during the frequent sandstorms that occur in the species' natural range.

Foot Structure

Each foot has two broad toes with undivided soles that can spread widely, an adaptation for walking on sand.

Foot Durability

The feet are very tough, suited to survival in extreme environments.

Migratory Behavior and Habitat Range

Bactrian camels are migratory, and their natural habitat spans rocky mountain massifs, flat steppe, arid desert (most commonly the Gobi Desert), stony plains and sand dunes.

Habitat Conditions

Habitat conditions are extremely harsh, with sparse vegetation, limited water sources, and extreme temperatures.

Temperature Tolerance

The Bactrian camel's coat allows it to withstand winter temperatures as low as −30 °C (−22 °F) and summer temperatures up to 50 °C (122 °F).

Water-Related Distribution

The species' distribution is tied to water availability: large groups gather near rivers after rain, at the foot of mountains where they can get water from springs in summer, and from snow in winter.

Ovulation Mechanism

Bactrian camels are induced ovulators, meaning they ovulate after insemination (semen is inserted into the vagina); ovulation is induced by the seminal plasma, not the spermatozoa themselves.

Ovulation Timing

87% of females ovulate after insemination: 66% ovulate within 36 hours, and the remaining ovulate by 48 hours, matching the timeline for natural mating.

Minimum Semen Volume for Ovulation

The minimum volume of semen required to trigger ovulation is approximately 1.0 ml.

Mating Season Male Behavior

Males often become quite violent during mating season, and may bite, spit, or attempt to sit on other male camels.

Sexual Maturity Age

The age of sexual maturity varies, but is typically reached between 3 and 5 years old.

Gestation Period

Gestation lasts around 13 months.

Calf Production Frequency

Bactrian camels produce one calf, or occasionally two, and females can give birth to a new calf every other year.

Neonatal Traits

Young Bactrian camels are precocial: they are able to stand and run shortly after birth, and they are fairly large, with an average birth weight of 36 kg (79 lb).

Nursing Duration

Calves are nursed for about 1.5 years.

Juvenile Maternal Association

A young calf stays with its mother for three to five years, until it reaches sexual maturity, and often helps raise the mother's subsequent offspring during this time.

Wild and Domestic Interbreeding

Wild Bactrian camels sometimes breed with domesticated or feral Bactrian camels.

Domesticated Range

Bactrian camels have been domesticated for thousands of years, and are widely bred by pastoralist and agricultural communities across Central Asia, the Middle East, and parts of China and Mongolia.

Breeding Selection Traits

Breeding practices differ by region, but most focus on selecting for traits including hardiness, milk production, load-bearing ability, and temperament.

Mongolian Breeding Practices

In Mongolia, herders have traditionally managed breeding through selective mating during the rutting season, often using older, experienced bulls known for their vigor and fertility.

Mongolian Mating Management

These males are isolated with females to encourage mating and reduce aggression toward other camels.

Iran and Afghanistan Breeding

In Iran and parts of Afghanistan, camel breeding is commonly integrated into mixed farming systems, where camels provide transport and milk alongside other livestock.

Central Asian Artificial Insemination

Semen collection and artificial insemination techniques are increasingly used in breeding programs in Central Asia, particularly in Kazakhstan and Uzbekistan, to improve genetic stock and ensure ovulation timing aligns with optimal conditions for conception.

Xinjiang Breeding Operations

In China’s Xinjiang region, both government-supported operations and private breeders run large-scale camel farms, focused on conserving the genetics of domesticated Bactrian camels and improving reproductive efficiency.

Calving Rate Improvements

Advances in veterinary care, nutritional supplementation, and controlled breeding environments have increased calving rates in recent decades.

Seasonal Breeding Timing

Across all these regions, breeding cycles are timed to match favorable seasonal conditions to maximize calf survival.

Female Breeding Frequency

Female camels are usually bred every two years to allow full recovery after gestation and lactation, although higher-frequency breeding is sometimes practiced under intensive management systems.

Offspring Uses

Offspring are commonly used for transportation, wool production, or sold in local markets, forming a critical part of the livelihood for many camel-rearing communities.

Indian Army Patrol Use

The Indian Army uses Bactrian camels to patrol Ladakh.

Ladakh Patrol Suitability Study

After carrying out trials and a comparative study with single-humped camels brought from Rajasthan, it was concluded that the double-humped Bactrian camel is better suited for this patrol task.

Bactrian Camel Patrol Capabilities

Colonel Manoj Batra, a veterinary officer of the Indian Army, stated that double-humped camels "are best suited for these conditions. They can carry loads of 170 kilograms (370 lb) at more than 17,000 feet (5,200 m) which is much more than the ponies that are being used as of now. They can survive without water for at least 72 hours."

Russian Military Use in Russo-Ukrainian War

The Russian Ground Forces has used Bactrian camels in the 2022–present Russo-Ukrainian war to carry heavy loads such as ammunition and supplies to the frontline.

Early Russian Camel Use Reports

Russian forces have been reported to use camels for transport as early as February 2025.

Captured Deserted Camel

On 28 October 2025, the Ukrainian Ground Forces captured a camel that had been deserted by Russian forces during a Ukrainian counteroffensive near Kharkiv.
