Genetic benefits of genomic selection breeding programmes considering foreign sire contributions

Table 7 Predicted cumulative NPV relative to a base scenario with zero foreign sire contributions

Foreign genetic trend	RSC	FSC	RSC	FSC
Foreign genetic trend	High (0.5)		Low (0.2)
Low (0.08)	2.21	1.82	− 0.02	− 0.11
Equal (0.10)	3.11	2.46	0.54	0.52
High (0.12)	4.22	3.09	1.37	1.15

Results reported in units of standard deviation of the true breeding goal per cow at 20 years for scenarios modelling the impact of introducing foreign sires at high and low starting sire merit with low, equal, and high foreign genetic trends relative to the domestic trend and sire contribution type
NPV net present value, RSC responsive sire contributions, FSC fixed sire contributions
