Tracking which genes an animal receives from its parents, using genetic markers allows to reduce generation intervals drastically.
Accurate selection of the best animals at an early age has always been one of the holy grails in animal breeding. The development of genomic selection is an important step towards achieving this in a cost-effective way, and is therefore termed as the “most significant development in animal breeding and genetics in the last two decades”.
Genomic selection relies on tracking which genes an animal receives from its parents, using so-called genetic markers. With this knowledge, the animals’ breeding value can be predicted accurately in life. Genomic selection thereby relaxes the need to have performance records on each selection candidate or its close relatives, and allows to reduce generation intervals drastically.
Animal Breeding and Genomics Centre
Within the Animal Breeding and Genomics Centre of Wageningen University & Research Livestock Research we have several projects to develop methodology to estimate genomic breeding values, to predict the accuracy of genomic selection and to optimize design of reference populations.
