They distinguish systematic "breeding"—the interference in normal sexual patterns—by enslavers with an aim to increase fertility or encourage desirable characteristics—from pronatalist policies, the generalized encouragement of large families through a combination of rewards, improved living and working conditions for fertile women and ...
Animal breeding is a branch of animal science that addresses the evaluation (using best linear unbiased prediction and other methods) of the genetic value (estimated breeding value, EBV) of livestock. Selecting for breeding animals with superior EBV in growth rate, egg, meat, milk, or wool production, or with other desirable traits has ...
In order to be considered fully domesticated, most species have undergone significant genetic, behavioural and morphological changes from their wild ancestors, while others have changed very little from their wild ancestors despite hundreds or thousands of years of potential selective breeding. A number of factors determine how quickly any ...

A stud farm or stud in animal husbandry is an establishment for selective breeding of livestock. The word "stud" comes from the Old English stod meaning "herd of horses, place where horses are kept for breeding". [1] Historically, documentation of the breedings that occur on a stud farm leads to the development of a stud book. Male animals made ...
Many animal species have specific mating (or breeding) periods e.g. (seasonal breeding) so that offspring are born or hatch at an optimal time. In marine species with limited mobility and external fertilisation like corals , sea urchins and clams , the timing of the common spawning is the only externally visible form of sexual behaviour.
Artificial insemination of farm animals is common in the developed world, especially for breeding dairy cattle (75% of all inseminations). Swine are also bred using this method (up to 85% of all inseminations). It is an economical means for a livestock breeder to improve their herds utilizing males having desirable traits.
