The process of identifying and removing undesirable animals from the herd.

The process of removing animals that are below average in production, unsound or undesirable.

Removing animals from the herd to assist in herd improvement and maintain herd size. Selection criteria are normally based on factors such as disease, infertility, milk yield, etc.

Originally meant to limit breeding stock by not breeding undesirable animals. In the rodent world, culling almost always means euthanizing part of a large litter or undesirable or infertile animals. (Also called "thinning" when refering to euthanizing part of a litter to make it smaller.)

The process of eliminating less productive or less desirable animals from a herd.

The process of selecting only the best rabbits from a litter for future breeding and show stock by selling or slaughtering the least desirable specimens from a litter.

The elimination of pups in large litters. This is best left to the mother of the litter, who will cull as required, beginning with the weakest pup.

Killing an animal from a population to reduce or stabilise the population

the action of terminating bettas that are either flawed, defective or sick and that the breeder does not want to keep because they cannot be bred or sold.

killing inferior fowl in order to improve the flock's health and quality.

Selective removal of animals for conservation purposes so other species can have food. Scientifically debatable process.

Careful examination for the purpose of selecting or rejecting.

Culling is the process of selection of surplus animals from an animal population. In a wild population the selection is often done by destroying the animal immediately, in a domesticated 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.

The process of eliminating a front face or back face of a polygon so that it isn't drawn.

The removal of non-archival material from file units during the processing of a series. The documents removed may be returned to the donor, donated to another archival institution, or destroyed.

Removing invisible pieces of geometry and only sending potentially visible geometry to the graphics subsystem. Simple culling involves rejecting objects not in the view frustum. more complex systems take into account occlusion of some objects by others, e.g. building hiding trees behind it.

Removing, from the processing pipeline to spare unneeded work, complete objects and surfaces which are completely hidden by other objects, or are facing away from the viewer (i.e. Backface culling) .

Culling is a process for determining items not to draw during the render of a scene. JetStream does a level of prioritized culling with the drop-out method of rendering interactive scenes, but you have a certain level of control over other aspects of culling such as backface, near and far planes.

Skipping a back face of a 3-D primitive during the rendering process.

In 3D graphics: The process of removing non-visible geometry before drawing it to increase efficiency. [ edit
