DESCRIPTION OF NATIONAL GENOMIC EVALUATION SYSTEMS

Country (or countries)	ITALY	
Main trait group1
NOTE! Only one trait group per form!	PRODUCTION	
Breed(s)	SIMMENTAL	
Trait definition(s) and unit(s) of measurement2
Attach an appendix if needed	Milk, fat and protein kg	
Source of genotypes (chips used)	ILLUMINA 54 v1/v2	
Imputation method for missing genotypes	yes	
Propagation of genomic information to non-genotyped descendants and ancestors	No propagation	
Animals included in reference population (males, females, countries included, total number)	Males,
ITALY, GERMANY and AUSTRIA (1.647 bulls)	
Source of phenotypic data (DYD, deregressed proofs, national EBVs and/or MACE evaluations)	Deregressed proofs from national and MACE evaluation	
Other criteria (data edits) for inclusion of records	Based on genotypes, individuals that are incompatible with their
declared parents are removed. Also, animals with call rate (fraction
of markers with genotype results) < 0.90 were removed. Only SNP
with minor allele frequency > 0.01 were included.
Animals with more than 3,000 missing genotypes and with inconsistencies in the mendelian inheritance were excluded from the analysis. Edits on SNP were based on the number of missing records (MISSING < 0.025), Mendelian inheritance conflicts, absence of heterozygous individuals, minor allele frequency (MAF < 0.02), deviance from Hardy-Weimberg equilibrium (HWE < 0.001).	
Criteria for extension of records (if applicable)	None	
Sire categories	AI Bulls	
Genomic model (linear, Bayesian, polygenic effect, genotypes or haplotypes)	Snpblup model.	
Blending of direct genomic value (DGV) with traditional EBV	YES:
gEBV = (Edc_EBV*EBV + edc_DGV *DGV) / (edc_EBV + edc_DGV)
EBV = Traditional estimated breeding value
DGV= Direct Estimated Genmic value
gEBV=Genomically Enhanced Estimated Breeding Value	
Environmental effects in the genetic evaluation model	None	
Adjustment for heterogeneous variance in evaluation model	None	
Computation of genomic reliability	Genomic reliability of gEBV:
(edc_EBV + edc_DGV) / ( (edc_EBV + edc_DGV) + k)
where     k = (4- h2)/h2	
Blending of foreign/Interbull information in evaluation	None	
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	Internal validation: rel pedigree index vs rel GEBV.	
Expression of genetic evaluations
If standardised (e.g. RBV), give standardisation formula in the appendix	As traditional pubblication of EBVs	
Definition of genetic reference base	cows born in 2010	
Labeling of genomic evaluations	GEBV	
Criteria for official publication of evaluations	Official since December 2015 for selection of young bulls; published only for :
•	bulls having no daughters or less than 20 daughters with at least 4 testday records each.
•	young bulls after 2 months from starting date of semen distribution	
Number of evaluations / publications per year	3 calibration and 6 pubblications	
Use in total merit index	None	
Anticipated changes in the near future	Applying SINGLE STEP model by using genomic relationship matrix

1) Either: Production (e.g. milk, fat, protein), Conformation, Health (e.g. mastitis resistance, milk somatic cell, resistance to diseases other than mastitis), Longevity, Calving (e.g. stillbirth, calving ease), Female fertility (e.g. non-return rate, interval between reproductive events, number of AI’s, heat strength), Workability (e.g. milking speed, temperament), Beef production, Efficiency (e.g. body weight, energy balance, body conditioning score), or Other traits.

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.
