Animal species’ dietary requirements are directly influenced by their domestication. For this case study, we’ll divide it into four categories and discuss the impact in comparison to wild counterparts.
Wild: These populations go through their whole life cycle without the intervention of humans. They can forage or hunt for their entire dietary requirements as needed.
Because they are reliant on people for nutrition, the following categories are unable to follow their natural feeding impulses and requirements.
- Raised in Captivity
- Captured from Wild
- Raised commercially
Raised in Captivity/Captured from Wild (in zoos, botanical gardens or for human gain): These populations are nurtured by humans but (except in zoos) not normally bred under human control. They remain as a group essentially indistinguishable in appearance or behaviour from their wild counterparts. Examples include Asian elephants, animals such as sloth bears and cobras used by showmen in India, and animals such as Asian black bears (farmed for their bile), and zoo animals, kept in captivity as examples of their species. (It should be noted that zoos and botanical gardens sometimes exhibit domesticated or feral animals and plants such as camels, mustangs, and some orchids
Raised commercially (captive or semi-domesticated): These populations are ranched or farmed in large numbers for food, commodities, or the pet trade, commonly breed in captivity, but as a group are not substantially altered in appearance or behaviour from their wild cousins. Examples include the ostrich, various deer, alligator, cricket, pearl oyster, raptors used in falconry and a ball python. (These species are sometimes referred to as partially domesticated.)
Domesticated: These populations are bred and raised under human control for many generations and are substantially altered as a group in appearance or behaviour. Examples include sweet potato, garlic, pigs, ferrets, turkeys, canaries, domestic pigeons, goldfish, koi carp, silkworms, dogs, cats, sheep, cattle, chickens, llamas, guinea pigs, laboratory mice, horses, goats and (silver) foxes.
As a result, animals often suffer from the following:
- Food intolerance and allergies due to additives in their food
- Bad breath
- Bad teeth
- Skin allergies and related illnesses
