DESCRIPTION OF NATIONAL GENETIC EVALUATION SYSTEMS

Country (or countries)	POLAND	
Main trait group1
NOTE! Only one trait group per form!	FEMALE FERTILITY	
Breed(s)	POLISH HOLSTEIN-FRIESIAN	
I	hco: conception rate for heifer
crc: interval from calving to first insemination
cc1: conception rate for older cow
cc2: days open (interval from calving to conception)
int:  days open (interval from calving to conception) 	
Method of measuring and collecting data	Data are routinely collected in national milk recording system 	
Time period for data inclusion	Calvings since 1995	
Age groups (e.g. parities) included	Heifers and cows (three parities)	
Other criteria (data edits) for inclusion of records		
Criteria for extension of records (if applicable)	Records are not extended	
Sire categories	All	
Environmental effects3, pre-adjustments 	None	
Method (model) of genetic evaluation3	MT BLUP AM for crc, cc2, int
MT BLUP AM for conception rate in three parities
hco=cr1,  cc1=average of cr2 and cr3 weighted by repeatability	
Environmental effects3 in the genetic evaluation model	Herd-Year (fixed), Month of calving (fixed), Age of calving – linear regression (fixed) for crc, cc2 and int.
Year-Month of insemination (fixed), Age at first insemination - linear regression (fixed), Herd-Year of first insemination (random) and additive animal effect for hco and cc1.	
Adjustment for heterogeneous variance in evaluation model	None	
Use of genetic groups and relationships	Based on sex, birth-year and HF percentage	
Blending of foreign/Interbull information in evaluation	None	
Genetic parameters in the evaluation	Use Appendix GE 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	Method 3	
Expression of genetic evaluations
If standardised (e.g. RBV), give standardisation formula in the appendix	Breeding Values are standardized to mean 100 and SD of 10	
Definition of genetic reference base
Next base change	Bulls born between 2009 and 2011 with at least 50 daughters in at least 30 herds	
Calculation of reliability	Yes	
Criteria for official publication of evaluations	At least 10 daughters	
Number of evaluations / publications per year	3	
Use in total merit index4	Yes, fertility subindex is used in total merit index with weight of 15%	
Anticipated changes in the near future		
Key reference on methodology applied	Genetic evaluation for fertility traits in Polish Holsteins

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).
