Genomic selection strategies in a small dairy cattle population evaluated for genetic gain and profit

Publikation: Bidrag til tidsskrift/Konferencebidrag i tidsskrift /Bidrag til avisTidsskriftartikelForskningpeer review

Small dairy cattle populations are challenged because of the low reliabilities of genomic predictions. We have demonstrated that low reliabilities of genomic predictions sets limitations for moving towards more genetic efficient breeding schemes with more intensive use of young bulls without progeny testing. Strong positive interaction effects between increased reliability of genomic predictions and more intensive use of young bulls exist. From an economic perspective a juvenile scheme is always advantageous. The main future focus area for the smaller dairy cattle breeds is to join forces that increase reliabilities of genomic predictions.
