Integration of beef cattle international pedigree and genomic estimated breeding values into national evaluations, with an application to the Italian Limousin population

Table 2 Overview of the implemented scenarios: names, data and purpose^a

Scenario	Scenario type	Data^a,b			Purpose
Scenario	Scenario type	Origin	Prior to January 2019	January 2019 to April 2019	Purpose
NAT_JAN	Input	National	⬤		Used to avoid double-counting in BLEND_APR
NAT_JAN	Input	Foreign			Used to avoid double-counting in BLEND_APR
INT_JAN	Input	National	⬤		Publishable sires’ information to be integrated into BLEND_APR
INT_JAN	Input	Foreign	⬤
NAT_APR	Validation	National	⬤	⬤	A national evaluation without integration. Used for comparison with BLEND_APR
NAT_APR	Validation	Foreign
BLEND_APR	Validation	National	⬤	⬤	A blended national evaluation that integrates publishable sires’ information of INT_JAN (corrected for NAT_JAN) into NAT_APR
BLEND_APR	Validation	Foreign	⬤
REF_{APR_trunc}	Reference	National	⬤	⬤	Reference scenario to validate scenarios’ adequacy
REF_{APR_trunc}	Reference	Foreign	⬤		Reference scenario to validate scenarios’ adequacy
REF_APR	Reference	National	⬤	⬤	Reference scenario to validate scenarios’ predictivity
REF_APR	Reference	Foreign	⬤	⬤	Reference scenario to validate scenarios’ predictivity

National = Italian phenotypes; Foreign = phenotypes and genotypes from other countries except Italy; ⬤ = data used in the scenario.
^aThe integration procedure was tested with or without genotypes in international evaluations; national evaluations were always pedigree-based
Input = scenarios the output of which is used as input in validated scenarios; Validation = scenarios validated and compared; and Reference = scenarios used as reference
^bAll scenarios used the full international pedigree
