Culling Totally Explained

Everything about Culling totally explained

Culling is the 'selection' (removing or killing) of surplus animals from an animal population. In a wild population the selection is often done by killing the animal immediately. In a domestic situation the culling process involves selection and the selling of surplus stock. The selection may be done to improve breeding stock, for example for improved production of eggs or milk, or simply to control the group's population for the benefit of the environment and other species.
   Culling for population control is common in wildlife management, particularly on African game farms and in Australia in national parks. In the case of very large animals such as elephants, adults are often targeted. Their orphaned young, easily captured and transported, are then relocated. Without proper elephant socialization, young male elephants are believed to become unruly and dangerous to other elephants, wildlife and humans. Culling is controversial in many African countries, but reintroduction of the practice has been recommended in recent years for use at the Kruger National Park in South Africa, which has experienced a swell in its elephant population since culling was banned in 1995.
   In fishing tournaments, culling refers to releasing smaller fish that won't be used to count towards an angler's total weight. For instance, if an angler is allowed to weigh in only 4 fish, he might keep his first four 2 pound fish in the livewell until he starts to catch bigger fish. As he catches bigger fish, he can release (or cull) the smaller fish.
   Also, in the United States, game animals such as elk may be informally culled if they begin to excessively eat winter food set out for domestic cattle. In such instances the rancher will inform hunters that they may "hunt the haystack" on his property in order to thin the local herd to levels that don't excessively impact the winter feed supplies. Other instances include issuance of extra hunting licenses or additional "special seasons" during harsh winters or overpopulation by state fish and game agencies.
   In certain cases culling may also be undertaken to check outbreak of certain viral or other infections and diseases among animals or birds. This has become widespread in India and some other East Asian countries where there are outbreaks of the deadly H5N1 virus among poultry. Huge number of chickens and some other fowls are being culled (as of January 2008) in order to contain spread of the avian flu.
   Culling would require a lot of safety steps to be maintained in such cases of culling animals/birds since even a minor fault can cause the infections to spread out from the affected animals/birds to the population at large. Safety measures may include wearing special protective clothing and breathing apparatus to keep the workers culling the affected animals/birds.
   Chick slaughtering is the culling of newly hatched male chickens for which breeders have no use. In an industrial egg-producing facility, about half of the newly hatched chicks will be male and would grow up to be roosters, which don't lay eggs and therefore there's no incentive for the breeder to keep alive. Most of the male chicks are usually killed shortly after hatching.
