DESCRIPTION OF NATIONAL GENOMIC EVALUATION SYSTEMS

Country (or countries)	Australia	
Main trait group1
NOTE! Only one trait group per form!	Production	
Breed(s)	HOL, JER	
Trait definition(s) and unit(s) of measurement2
Attach an appendix if needed	Milk in liters, fat and prot in kg	
Source of genotypes (chips used)	Illumina 50K1 and 2, 3K, 9K	
Imputation method for missing genotypes	Beagle	
Propagation of genomic information to non-genotyped descendants and ancestors	No	
Animals included in reference population (males, females, countries included, total number)	Holstein: 3416 Males, 9604 females, total 13020; various countries
Jersey: 948 Males, 4247 females, total 5195; various countries	
Source of phenotypic data (DYD, deregressed proofs, national EBVs and/or MACE evaluations)	DYDs based on national data only	
Other criteria (data edits) for inclusion of records	At least 10 dtrs	
Criteria for extension of records (if applicable)	-	
Sire categories	All	
Genomic model (linear, Bayesian, polygenic effect, genotypes or haplotypes)	Linear, no polygenic, genotypes	
Blending of direct genomic value (DGV) with traditional EBV	Yes, Harris & Johnson
With DGV explaining 80% of genetic variation
Conventional EBV for bulls with <10 dtrs and cows with no own records regressed with factor 0.7 in blending procedure	
Environmental effects in the genetic evaluation model	HYS, age group	
Adjustment for heterogeneous variance in evaluation model	-	
Computation of genomic reliability	Gblup, EDC calculated as lamba*rel/(1-rel) where lambda=11	
Blending of foreign/Interbull information in evaluation	No	
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		
Expression of genetic evaluations
If standardised (e.g. RBV), give standardisation formula in the appendix	Absolute	
Definition of genetic reference base	Annual adjustment based on cows born 4 to 8 years ago	
Labeling of genomic evaluations	Yes	
Criteria for official publication of evaluations	63% and 15 herds, or genomic	
Number of evaluations / publications per year	2	
Use in total merit index	Yes	
Anticipated changes in the near future	-

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.

Parameters used in genetic evaluation

Country (or countries): 	AUS	
Main trait group: 	Yield	
Breed (repeat as necessary): 	HOL	

Trait	Definition	ITBa	h2b	genetic
varianceb	official proof
standardisation formulac	
						
Milk	305 days	X	.25		-	
Fat	305 days	X	.25		-	
Protein	305 days	X	.25		-	

						

						

						

						
						
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.
