Answer:
In animal breeding people select the animals that will produce the next generation of animals that are on average superior than the present generation of animals.
Selection by nature, natural selection, is very important for the adaptation of animals to the circumstances they are kept.
An important prerequisite for the success of animal breeding is that traits are heritable, which implies that the ability for the trait is passed on from parents to progeny.
Domestication of animals started with the dog. Later on the farm animals were domesticated. Domestication of a species requires specific traits. Within the domesticated species the process is still going on due to new requirements caused by changing circumstances.
Selective animal breeding started 250 years ago with the formation of breeds and herd books. The scientific base for animal breeding is developed in the 20-th century. The application of scientific developments in reproduction in the past 50 years made animal breeding more effective. Recently it got a strong impulse from developments in molecular genetics.
Breeding activities are directly be influenced by and are related to developments in society: required food production by animals and requirements of mankind for animals as companion and for leisure purposes.
Breeding programs with cattle, pigs and poultry yielded sharp increases in the quantity of milk, meat or eggs. Also capabilities of horses improved sharply.
Breeding of animals did not only give positive results: in dogs inbreeding and one-sided selection for conformation traits resulted in dogs with more health problems and less welfare. In farm animals selection for yield implies a risk for a deterioration of quality and fitness traits.
