Captive elephants

Elephants can be found in various places such as a zoo, sanctuary, circus, or camp, usually under veterinary care. They are often used for educational purposes, for entertainment, or for work.

The history of keeping elephants in captivity goes back a very long time. The earliest evidence of captive elephants dates to the Indus Valley Civilization about 4,500 years ago. Since then, elephants have been used around the world in war, ceremony, and for labor and entertainment. The first elephant arrived in North America in 1796, and London Zoo, the first scientific zoo, housed elephants beginning in 1831.

Before the 1980s, zoos got their elephants by capturing them from the wild. But as wild elephant numbers decreased, zoos began breeding elephants in captivity instead. The first successful birth of an Asian elephant in North America happened at the Oregon Zoo in 1962, and the first African elephant birth took place at the Knoxville Zoological Gardens in 1978. Today, most zoos get their elephants through breeding.

In 2006, there were 286 elephants in American zoos, with 147 African elephants and 139 Asian elephants. Many Asian elephants live in captivity, with about 15,000 in work camps, temples, and ecotourism sites. The wild population of Asian elephants is estimated to be between 40,000 and 50,000, while the wild population of African elephants is estimated to be between 400,000 and 600,000, according to the International Union for Conservation of Nature (IUCN).

History

Further information: Cultural depictions of elephants

Elephants have been kept by people since around 2,000 BCE in the Indus Valley civilization. They have helped with jobs like working in forests and even fighting in battles led by leaders like Hannibal. Elephants have also been important in cultural events, such as being part of temples, and have been shown in places like circuses, elephant polo games, and zoos.

The idea of a white elephant comes from a special white elephant that was too sacred to work. Long ago, the kings of Siam would give these elephants to people they did not like, knowing it would cost a lot to care for them.

Behaviour and training

Further information: Elephant cognition and Animal training

Elephants have the biggest brains of all land animals and have been known for their smart behaviors since ancient times. They share many behaviors with humans, such as feeling sadness, learning new things, helping each other, and remembering. In the wild, elephant groups are led by a female called a matriarch. When male elephants grow up, they usually leave the group and may join other males.

In places where elephants are kept, it can be hard to give them the same social life they would have in the wild. Male elephants can become very aggressive when they are looking for mates, which can be dangerous.

Elephants in captivity can be trained to do different jobs. They can remember commands and sounds, which helps them learn. In Nepal, elephants help forest rangers and entertain tourists. In Myanmar, they help with logging. In North America, Australasia, and Europe, they often work in circuses or zoos.

There are different ways to train elephants. In "free contact," the elephant and trainer are together without a barrier. This can be good for exercise but can be dangerous. In "protected contact," there is a barrier, and training uses rewards. In "no contact," elephants are only handled when they are calm from medicine. Each method has its own good and bad points for the elephants and the trainers. Some places use a mix of these methods depending on the elephants.

Reproduction

Most elephant groups kept in places like North America, Europe, and Asia cannot grow on their own. Without more babies or new elephants from the wild, some of these groups might disappear in the next 50 years. This happens because many female elephants cannot have babies and there are too many males compared to females.

To help more baby elephants be born, people work hard to increase the number of births. Moving elephants between places for breeding can be very hard and stressful for the elephants. It might be better to move young males, who would naturally leave their families in the wild, instead of females, who usually stay with their families.

Because moving elephants can be so difficult, some caretakers use a method called artificial insemination to help female elephants have babies. This can use semen from males in other places or from wild males to keep the group of elephants more diverse.

Hand-rearing

When baby elephants lose their mothers, special care is needed to help them grow. The right milk mix is very important. People often use human infant milk but add extra things like special cow milk, certain bacteria, and fats to help the babies stay healthy. They also add vitamins, minerals, and foods like rice water and rice cereal to help the babies get used to eating solid foods.

Welfare

Elephants are smart animals that need special care when they live in places like zoos. They need big spaces to move around and live with other elephants, just like they do in the wild.

In the wild, elephants walk long distances to find food and water, but in zoos, they have these things closer, so they don’t need to walk as much. Experts suggest that each elephant should have a lot of space to live in. Some zoos are working to keep elephants in bigger groups to make them happier.

People watch for certain behaviors to know if zoo elephants are healthy. For example, elephants that play in water or dust are showing they are comfortable, which is good. But if they pace back and forth a lot, it might mean they are not happy. Keeping elephants healthy and comfortable in zoos is very important.

Health

Infectious diseases

Tuberculosis

A report from the Centers for Disease Control found that about 2% of African and 12% of Asian elephants in North American zoos might have a sickness called tuberculosis.

Elephant endotheliotropic herpesvirus

Elephant endotheliotropic herpesvirus (EEHV) is a type of virus that has caused many young Asian elephant calves to become very sick or pass away, both in the wild and in captivity. In North America, it has been linked to 58% of deaths in young Asian elephants born in zoos between 1962 and 2007. There is no cure, but treatments like special medicines and care can help some elephants survive.

Noninfectious diseases

Foot and musculoskeletal diseases

Many captive elephants have problems with their feet, such as overgrown nails or painful sores. These issues can make it hard for them to walk, and sometimes zoos have to make very hard decisions to keep them comfortable. Elephants in the wild wear down their feet naturally by walking, so zoos try to help by giving them proper foot care.

Elephants can also develop joint and muscle problems, especially as they get older. These issues might be made worse by not having enough space or soft surfaces to walk on.

Obesity

A study found that many zoo elephants are overweight or obese. This might affect their health in ways we are still learning about, but it could be linked to problems like difficulty having babies, joint pain, and heart issues. Zoos are trying new ways to help elephants stay healthier by changing their diet and giving them more exercise.
