DESCRIPTION OF NATIONAL GENETIC EVALUATION SYSTEMS

Country (or countries)	Hungary	
Main trait group1
NOTE! Only one trait group per form!	Longevity	
Breed(s)	HOL	
Trait definition(s) and unit(s) of measurement2
Attach an appendix if needed	Risk of involuntary culling during a cow’s lifetime.  
Unit of measurement is productive life span (PLS) of cow in days	
Method of measuring and collecting data	PLS is calculated from the data from the milk recording system: the number of days between the first calving and the last test date. 
Culling and herd movement data are collected from the national 
Identification & Registration database.  	
Time period for data inclusion	Cows in production at or after January 1st 2000 with an official 
pedigree registration. 	
Age groups (e.g. parities) included	Parity 1 through 10	
Other criteria (data edits) for inclusion of records	Minimum age at first calving should be at least 640 days and at most 1200 days.
Bulls should have at least 15 daughters and/or granddaughters in the analysis. 
	
Criteria for extension of records (if applicable)		
Sire categories	All bulls with progeny information including domestic and foreign AI bulls	
Environmental effects3, pre-adjustments 	None	
Method (model) of genetic evaluation3	S-MGS Survival Analysis, applying a proportional hazard function following a Weibull distribution. 
Longevity is combined with 5 predictive traits in a selection index (amount of information of every trait is taken into account per bull) to increase the reliability. Predictors are calculated as breeding value – parent average. Predictors (with correlation) are: 
			correlation with longevity 

stature 				-0.24
rump angle 			-0.12 
udder depth 			0.41 
overall udder			0.38
log-somatic cell count		-0.41	
Environmental effects3 in the genetic evaluation model	Herd-Year-Season (R, time-dependent): Two seasons per year (starting at April 1 and October 1). 
Parity-Year-Season (F, time-dependent): Six seasons of 2 months starting at day 15 of an unequal month for parity 1 to 10. 
Herd-Size-Change (F, time-dependent): Changes at January 1st of each year or if a cow changes herd. 7 classes: size variation < -90%, -90% – -50%, -50% – -30%, -30% – -10%, -10% – 10%, 10% – 30%, >30%. If shrinkage > 90% records are censored.
Age at first calving (F, time-independent): 30 classes of 15 – 30 days each starting at 640 days. 
RP (C and P) : Relative Production: per year of calving the average and the standard deviation of the 305-day lactation yield, adjusted to age at calving of 27 months, of all cows in the herd is calculated. The relative production is divided into 20 classes per trait. The relative production class is calculated as: 
Relative production class =

*3.5    + 10.5

305-day lactation yield – herd average 	
standard deviation of herd
The minimum relative production class is 1 and the maximum class is 20. Relative production classes are calculated for milk, fat and protein yield in the current lactation n: RPCMn, RPCFn and RPCPn and the previous lactation o: RPPM o, RPPF o and RPPP o. The relative production classes change with each calving; 
Heterosis (F, time-independent): The heterosis effect has 10 classes.
Class 1 includes cows without heterosis, class 2 cows with 0.1 to 12.4 % heterosis, class 9 cows with 87.5 to 99.9 % heterosis and class 10 cows with 100 % heterosis. 
Recombination (F, time-independent): The recombination effect has 10 classes. Class 1 includes cows without recombination, class 2 cows with 0.01 to 6.24 % recombination, class 9 cows with 43.8 to 49.9 percent recombination and class 10 cows with 50 % recombination. 
Genetic Group of the maternal dam (F, time-independent): Based on breed of mgd and the cows year of birth (5 years per class, 1 year for all Holstein classes). 	
Adjustment for heterogeneous variance in evaluation model	No	
Use of genetic groups and relationships	Unknown parents in the sire pedigrees are grouped together according to breed and year of birth.  
A sire-maternal grandsire model is applied where sire and maternal grandsire of the sire and maternal grandsire of the cow are used in the evaluation.	
Blending of foreign/Interbull information in evaluation	No	
Genetic parameters in the evaluation	sire variance (log scale) 0.0153,  gamma 3.64,  h
rho’s were estimated per parity (1,2 and 3+) * stage of lactation (0-15, 16-40,41-140,141-240,241-370, 370+, dry)  
Parity	1	2	3
Days in lactation	ρ
0-15	1.58	2.30	2.46
16-40	3.18	3.27	3.11
41-140	1.14	1.22	1.19
141-240	1.84	2.18	2.08

>370	2.43	2.03	1.71
Dry period	0.00	0.00	0.00	
System validation	Interbull test 2	
Expression of genetic evaluations
If standardised (e.g. RBV), give standardisation formula in the appendix	RBV with mean of 0 and SD 1. Higher RBV indicates better 
longevity.	
Definition of genetic reference base
Next base change	AI bulls born between 1-1-2008 and 31-12-2012 with reliability of at least 50 percent. 
2025	
Calculation of reliability	Reliability according to Meyer (LPS 21: 87 – 100) with h2 on original scale and number of observations = number of culled daughters + 0.5 * number of culled maternal granddaughters. 	
Criteria for official publication of evaluations	Number of daughters for milk >=20 AND number of herds for milk>=10 AND number of daughters for type>=5 AND number of herds for type >=3 AND RELMilk>=60	
Number of evaluations / publications per year	3	
Use in total merit index4	HOL: HGI=Holstein Global Index

Where:
