The artificial insemination (KB) is a method of procreation, in which semen collected a male breeding animal and instrumentally introduced into the sexual organs of a female breeding animal.

This method is used as an alternative to natural jumping, for example for domestic cattle and domestic pigs, but also for domestic horses and honey bees . The sperm then move actively through the fallopian tubes towards the egg cell, so that one sperm can penetrate each egg cell . With the subsequent fusion of the two nuclei of the egg cell and sperm, the actual fertilization is complete. To determine the optimal point in time, the progesterone test is carried out , among other things . In Austria it is noted in the heat calendar .

If artificial insemination is not promising, artificial insemination ( in vitro fertilization ) can be carried out in reproductive medicine in both humans and animals .

Advantages compared to natural insemination by copulation (natural jump) are, for example, that special sires and refiners can be used as sire animals who live in distant places, protection against covering infections and injuries, the relief of heavily frequented sire animals and the insemination of a large number of females Animals.

In cattle breeding, frozen semen is mainly used , in horse breeding both fresh and frozen semen are used.

In the breeding of English thoroughbreds , artificial insemination - of any kind - is internationally prohibited. A horse conceived in this way will not be entered in the studbook for racehorses and may not take part in public races.

Artificial insemination of queen bees has become an important part of breeding.
