Reproductive Technologies and Genomic Selection in Cattle
The recent development of genomic selection induces dramatic changes in the way genetic selection schemes are to be conducted. This review describes the new context and corresponding needs for genomic based selection schemes and how reproductive technologies can be used to meet those needs. Information brought by reproductive physiology will provide new markers and new improved phenotypes that ...
متن کاملOptimising Multistage Dairy Cattle Breeding Programs with Regard to Genomic Selection
Multistage dairy cattle breeding schemes consisting of 4 selection paths were optimised in order to maximise the genetic gain per year with regard to genomic selection on 2 genomically estimated breeding values differing in costs and accuracy. Results clearly show that the selection of bull dams is the major field of application for low-density genotyping but also emphasise the selection of sir...
متن کاملOptimization of Swine Breeding Programs Using Genomic Selection with ZPLAN.
The objective of this study was to evaluate the present conventional selection program of a swine nucleus farm and compare it with a new selection strategy employing genomic enhanced breeding value (GEBV) as the selection criteria. The ZPLAN+ software was employed to calculate and compare the genetic gain, total cost, return and profit of each selection strategy. The first strategy reflected th...
متن کاملBreeding and Genetics: Genomic Selection in Dairy II
A posteriori and modified granddaughter designs were applied to determine haplotype effects for Holstein bulls and cows with BovineSNP50 genotypes. The a posteriori granddaughter design was applied to 52 sire families, each with > 100 genotyped sons with genetic evaluations based on progeny tests. For 33 traits (milk, fat, and protein yields; fat and protein percent; somatic cell score; product...
متن کاملIntegrating genomic selection into dairy cattle breeding programmes: a review.
Extensive genetic progress has been achieved in dairy cattle populations on many traits of economic importance because of efficient breeding programmes. Success of these programmes has relied on progeny testing of the best young males to accurately assess their genetic merit and hence their potential for breeding. Over the last few years, the integration of dense genomic information into statis...
