Inclusion of cow records in genomic evaluations and impact on bias due to preferential treatment

Table 3 Correlations between GEBV obtained when including both DYD and YD and when including only DYD for the elite and “randomly selected” groups of cows

Breed	Trait	Elite cows	Randomly selected cows
Montbéliarde	Milk yield	0.740	0.770
	SCC	0.915	0.893
Normande	Milk yield	0.768	0.820
	SCC	0.900	0.909
Holstein	Milk yield	0.931	0.938
	SCC	0.966	0.965

GEBV = genomically estimated breeding values; DYD = daughter yield deviations; YD = yield deviations; SCC = somatic cell count.
