Definition of the Subject

Animal breeding can be defined as a human activity with the deliberate purpose to change existing populations of animals in some desired directions, so that future generations of these animals become more valuable in some sense. A prerequisite for successful animal breeding is that there is a genetic variation in the population in the traits one want to improve in future generations. Other requirements are: clear definitions of the breeding goals, good pedigree files, valid measures of the desired traits, methods of genetic evaluations that can combine information from the pedigree and the measured trait, and finally effective selection of breeding animals with high estimated genetic values (BV = breeding values ) and therefore presumably with relatively large proportion of valuable genes affecting the desired traits.

The selected parents will transmit their genes to the next generation, and depending on the amount of genetic variation in the traits, accuracy...
