Validation of genomic predictions for body weight in broilers using crossbred information and considering breed-of-origin of alleles

Table 1 Overview of scenarios with information on the types of reference population, validation records, and genomic relationship matrix (GRM) that were used

Scenario^a	Reference population	Prediction	Validation	GRM
PB-A	PB offspring	Sire GEBV	Offspring averages	\({\mathbf{G}}\)
CB-A	CB offspring	Sire GEBV	Offspring averages	\({\mathbf{G}}\)
CB-A-BOA	CB offspring	Sire GEBV	Offspring averages	\({\mathbf{G}}_{BOA}\)
PB-I	PB offspring	CB GEBV	Individual records	\({\mathbf{G}}\)
CB-I	CB offspring	CB GEBV	Individual records	\({\mathbf{G}}\)
CB-I-BOA	CB offspring	CB GEBV	Individual records	\({\mathbf{G}}_{BOA}\)

^aIn the abbreviation of the scenarios, the first element indicates the reference population (PB or CB), the second element the validation record (CB offspring averages indicated by A or individual offspring records indicated by I), and a third element “BOA” is added for scenarios that consider BOA
