Optimization of Swine Breeding Programs Using Genomic Selection with ZPLAN+

Optimization 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...

Modelling genomic selection schemes in Bavarian pig breeding programs using ZPLAN+

Integration of genomic information into sport horse breeding programs for optimization of accuracy of selection.

Reliable selection criteria are required for young riding horses to increase genetic gain by increasing accuracy of selection and decreasing generation intervals. In this study, selection strategies incorporating genomic breeding values (GEBVs) were evaluated. Relevant stages of selection in sport horse breeding programs were analyzed by applying selection index theory. Results in terms of accu...

Economic evaluation of genomic breeding programs.

The objective of this study was to compare a conventional dairy cattle breeding program characterized by a progeny testing scheme with different scenarios of genomic breeding programs. The ultimate economic evaluation criterion was discounted profit reflecting discounted returns minus discounted costs per cow in a balanced breeding goal of production and functionality. A deterministic approach ...

Optimising 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...
