What do zoos do when animals are sick?

Zoo veterinarians can give animals routine vaccinations and physical exams to keep them healthy. Animals who are treated for a disease are kept in isolation to reduce exposure to other animals. In addition, animals with injuries are kept separate so they can heal properly.

Researchers at zoos can study animals up-close. They can observe behavior such as mating and nutrition choices. Biologists and veterinarians are also available to treat sick or injured animals. Captive breeding of endangered species makes zoos valuable places for animal survival.

One of the most common forms of mistreatment is inadequate and limited living conditions. For example, tigers and lions have about 18,000 times less space in their captive enclosures than what they would have in the wild, and polar bears have one million times less space.

That captivity can be REALLY bad for both physical AND psychological health. And while zoos have been really helpful is saving endangered animals, it doesn't work out for certain species. For example, most large carnivores like lions and tigers that are bred in captivity die when released into the wild.

Zoos can help to save endangered species by keeping them in a 'safe' environment. Safe as in protected from poachers, predators, habitat loss and even starvation. If a zoo has a breeding programme, this is another way to protect endangered species which may have trouble finding suitable mates in the wild.

MORE DETAILS

Captive animals seldom learn crucial survival skills and often are too habituated to human contact. Lacking a natural fear of humans, they are vulnerable to poachers and ill equipped for life in the wild.

Thankfully, zoo keepers have mastered many techniques to give animals medicine. Once in a while, there are medications that can be hidden in food or mixed with juice, depending on the animal. For primates, sometimes we can hide a pill in a grape, among other grapes.

Zoo visitors are often aspects of a zoo animal's environment that animals cannot control and as such can be stressful, although some species appear to show good adaptability for the changing conditions of visitors, said Dr Samantha Ward, from Nottingham Trent University.
