Animal welfare in zoos

The welfare of zoo animals varies widely. Many zoos work to improve their animal enclosures and make it fit the animals' needs, but constraints such as size and expense can complicate this. The type of enclosure and the husbandry are of great importance in determining the welfare of animals. Substandard enclosures can lead to decreased lifespans, caused by factors as human diseases, unsafe materials in the cages and possible escape attempts (Bendow 382). However, when zoos take time to think about the animal's welfare, zoos can become a place of refuge. Today, many zoos are improving enclosures by including tactile and sensory features in the habitat that allow animals to encourage natural behaviors. These additions can prove to be effective in improving the lives of animals in captivity. The tactile and sensory features will vary depending on the species of animal. There are animals that are injured in the wild and are unable to survive on their own, but in the zoos they can live out the rest of their lives healthy and happy (McGaffin). In recent years, some zoos have chosen to move out some larger animals because they do not have the space available to provide an adequate enclosure for them (Lemonic, McDowell, and Bjerklie 50).

An issue with animal welfare in zoos is that best animal husbandry practices are often not completely known, especially for species that are only kept in a small number of zoos. To solve this organizations like EAZA and AZA have begun to develop husbandry manuals.
