DESCRIPTION OF NATIONAL GENOMIC EVALUATION SYSTEMS

Country (or countries)	Switzerland (CHE)	
Main trait group1 NOTE! Only one trait group per form!	Production	
Breed(s)	BSW	
Trait definition(s) and unit(s) of measurement2 Attach an appendix if needed	Protein yield (kg)	
Source of genotypes (chips used)	Illumina BovineSNP50 BeadChip (v1 and v2).	
Imputation method for missing genotypes	No imputation.	
Propagation of genomic information to non-genotyped descendants and ancestors	Yes, PA of descendants calculated with GEBV of parents.	
Animals included in reference population (males, females, countries included, total number)	BSW males (Original Braunvieh animals are excluded) with a progeny proof of at least 80% reliability (domestic or MACE).	
Source of phenotypic data (DYD, deregressed proofs, national EBVs and/or MACE evaluations)	Deregressed proofs, calculated from EBV and PA.	
Other criteria (data edits) for inclusion of records	Genomic data was included only if the call rate was at least 80%	
Criteria for extension of records (if applicable)	NA	
Sire categories	NA	
Genomic model (linear, Bayesian, polygenic effect, genotypes or haplotypes)	Bayesian model (Bayes C) using genotypes, without polygenic effect.	
Blending of direct genomic value (DGV) with traditional EBV	Yes, according to Sullivan's (2009) method.	
Environmental effects in the genetic evaluation model		
Adjustment for heterogeneous variance in evaluation model		
Computation of genomic reliability	DGV reliability is identical for all animals and is calculated according to the following formula applied to validation bulls:
rel(DGV) = r2(DGV,EBV)/rel(EBV)

Reliability of GEBV is computed and is at least the highest of DGV and EBV reliabilities.	
Blending of foreign/Interbull information in evaluation	MACE evaluations are included in the SNP effect estimations.	
Genetic parameters in the evaluation	Use Appendix GENO for heritability/genetic variance estimates; for multiple-trait genetic evaluations, provide genetic correlation estimates between traits separately.
Use also appendices PR, CO, BCO, SM, LO, CA, as applicable, if you participate in the international genetic evaluations of Interbull	
System validation	Deregressed proofs of bulls with a first proof after April 2007 were predicted based on proofs of April 2007.	
Expression of genetic evaluations If standardised (e.g. RBV), give standardisation formula in the appendix	DGV standardization is based on reference bulls so that their mean DGV is equal to their mean deregressed proof and the regression of DGV on deregressed proof is forced to 1.	
Definition of genetic reference base	Cows born between 2003 and 2005	
Labeling of genomic evaluations	G for animals with domestic proof
GA for animals with parent average
GI for animals with international proof (MACE)	
Criteria for official publication of evaluations	All GEBVs are official. 	
Number of evaluations / publications per year	3 full releases (April, August, December)
Immediate releases of newly genotyped animals 	
Use in total merit index	GZW is calculated with genomic values.	
Anticipated changes in the near future

a	Indicate, with X, traits that are submitted to Interbull for international genetic evaluations.
b	If repeated records are treated as separate traits, provide heritability estimates and genetic variances separately for each trait, as well as for all traits pooled, i.e. for the trait submitted to Interbull.
c	Expressed as follows: StandEval=((eval-a)/b)*c+d where a=mean of the base adjustment, b=standard deviation of the base, c=standard deviation of expression (include sign if scale is reversed), and d=base of expression.
