DESCRIPTION OF NATIONAL GENETIC EVALUATION SYSTEMS

Country (or countries)	Poland	
Main trait group1
NOTE! Only one trait group per form!	Conformation	
Breed(s)	Polish Holstein-Friesian	
Trait definition(s) and unit(s) of measurement2	Stature, chest width, body depth, angularity, rump angle, rump width, rear leg set, foot angle, fore udder, rear udder height, central ligament, udder depth, fore teat placement, rear teat placement, teat length, final score, udder score, legs & feet score, locomotion, body condition score	
Method of measuring and collecting data	Linear or scoring measurements	
Time period for data inclusion	cows born since 1995	
Age groups (e.g. parities) included	First parity cows	
Other criteria (data edits) for inclusion of records	Appraisal is made between 15 and 180 day of  first lactation 	
Criteria for extension of records (if applicable)	None	
Sire categories	All sires are evaluated	
Environmental effects3, pre-adjustments 	None	
Method (model) of genetic evaluation3	ST  BLUP ‑ AM	
Environmental effects3 in the genetic evaluation model	Linear and quadratic regression on age at calving, herd‑year‑season-classifier (F), lactation stage (F)	
Adjustment for heterogeneous variance in evaluation model	None	
Use of genetic groups and relationships	The genetic groups based on unknown parents, sex, birth year and percentage of HF	
Blending of foreign/Interbull information in evaluation	Foreign evaluations are not blended
	
Genetic parameters in the evaluation	see appendix.
	
System validation	Genetic trend estimation by method 3 recommended by the Interbull	
Expression of genetic evaluations
If standardised (e.g. RBV), give standardisation formula in the appendix	RBV, standardised BV with mean=100 and standard deviation=10	
Definition of genetic reference base
Next base change	Bulls born between 2009 and 2011 with at least 10 evaluated daughters in at least 5 herds
	
Calculation of reliability	Approximation using selection index method
	
Criteria for official publication of evaluations	AI sires with min.10 daughters	
Number of evaluations / publications per year	3 	
Use in total merit index4	Conformation subindex is used in total merit index with weight of 25% 	
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.
2) Indicate frequencies per category if the trait is categorical and specify transformation of data if practiced.
3) Use abbreviations for most common effects (see document with list of abbreviations at http://www-interbull.slu.se/service_documentation/General/list_of_abbreviations.rtf) and indicate random (R) or fixed (F).
4) Please give economic weights and indicate how they are expressed (preferably in genetic standard deviation units).
