Table 2.

Predictive ability for harvest weight and residual carcass weight under BLUP and ssGBLUP for all validation scenarios

Validation strategy	Validation scenarios^a	Harvest weight		Residual carcass weight
Validation strategy	Validation scenarios^a	BLUP	ssGBLUP	BLUP	ssGBLUP
1	Five fold cross-validation^b	0.29^0.001	0.37^0.001	0.24^0.002	0.31^0.002
1	Ten fold cross-validation^b	0.29^0.0003	0.37^0.0004	0.24^0.002	0.32^0.002
2	Full sib validation	0.31	0.38	0.25	0.34
3	Half of the full sibs with phenotypes	–	–	0.23	0.28
4	No phenotypes for all genotyped animals	–	–	0.22	0.24

Predictive ability is measured by the correlation between (G)EBV and phenotypes adjusted for fixed effects in the validation population
