Rodent farming
Rodent farming is an agricultural process in which rodents are bred and raised with the intent of selling them for their meat. They are often categorised in a sub-category of livestock known as micro-livestock, due to their small size. Rodents have been used as food in a wide range of cultures, including Hawaiian, Vietnamese, French, Indian and Thai.
Rodent farming has been suggested as a solution to the world's increased requirements for food associated with an increasing population as a result of a number of perceived benefits with their production and consumption.
As food
Rodents have been hunted and farmed in a number of cultures. The polynesian rat was hunted and consumed by the common people in pre-contact Hawaii.[1] Capybaras, agoutis, and guinea pigs have historically been eaten in South America -- guinea pigs were farmed as far back in 2500 BCE in what is now Peru.[2] Cane rats can grow up to 60 cm in length and weigh up to 10 kg and are hunted as bush meat in western and central Africa.[2] Rats were commonly eaten during the Tang Dynasty in China; they may have been domesticated as they were called “household deer”.[2] The Mishmi people in the Lohit district in India traditionally hunted rats.[3] Dishes with rats captured in wine cellars are described in Larousse Gastronomique and rats are eaten in rural Thailand.[4]
Farming
A perverse incentive led to rat farming in 1902, when rat catchers bred rats in the sewers of Hanoi to collect a reward that the colonial government of French Indochina offered for rat tails.[5]
In the contemporary era, rodent farming has been suggested as a sustainable agriculture method to address current global malnutrition and to meet the needs of the world's growing population.[2][6] Rodent farming can be economically efficient, since they can produce a large number of offspring per year, have a limited gestation period, and have a high feed conversion ratio.[2] They require little space, so could be farmed in urban areas.[2]
Efforts have been made to develop rat farming among the dalit in the Indian state of Bihar; one obstacle to this is that the animal vehicle of the god Ganesh is a rat.[7]
In Cameroon, cane rats is encouraged in economic development efforts.[2][8]
In Australia, a rat farm that provides food for zoos and pet stores was the subject of a 2018 profile.[9]
Management
Rodents can be kept in sheds or cages, and fed grain, pellets, or scraps.[2][9] In nations with strict animal cruelty regulations, such as Australia, the animals must be killed humanely, for example by gassing with carbon dioxide.[9] In nations without these regulations, it is more common for the animals to be killed by drowning or bludgeoning.[10]
