DESCRIPTION OF NATIONAL GENETIC EVALUATION SYSTEMS

Country (or countries)	ITALY	
Main trait group1
NOTE! Only one trait group per form!	Health	
Breed(s)	Simmental	
Trait definition(s) and unit(s) of measurement2
Attach an appendix if needed	SCS Test day from 6 to 360 days	
Method of measuring and collecting data	Test day records are collected each 4 weeks (A4 and AT methods) as well as each 6 weeks (A6 method) 	
Time period for data inclusion	Calving year from 1994 to today	
Age groups (e.g. parities) included	All parities	
Other criteria (data edits) for inclusion of records	Cows with at least 2 records in the first lactation and herd-test day classes with at least 3 records	
Criteria for extension of records (if applicable)		
Sire categories	All	
Environmental effects3, pre-adjustments 	None	
Method (model) of genetic evaluation3	TDM repeatability single trait	
Environmental effects3 in the genetic evaluation model	Herd test-date(F), Parity by age at calving by days in milk (F) by calving year (classes of 5 years), calving season (month) (F)	
Adjustment for heterogeneous variance in evaluation model		
Use of genetic groups and relationships	Relationship up to 10 generations and genetic groups for unknown parents	
Blending of foreign/Interbull information in evaluation		
Genetic parameters in the evaluation	See Appendix SM for heritability/genetic variance estimates; 	
System validation	Method 1	
Expression of genetic evaluations
If standardised (e.g. RBV), give standardisation formula in the appendix	RBV	
Definition of genetic reference base
Next base change	Cows born in between yyyy-7 and yyyy-5 where yyyy is currently year.

Every run	
Calculation of reliability	Accf90 program provided by I.Misztal	
Criteria for official publication of evaluations	Bulls with an official proof for production traits and reliability for SCS at least 50%	
Number of evaluations / publications per year	2	
Use in total merit index4	no	
Anticipated changes in the near future	Use in total merit index

Riunione della Commissione Tecnica Centrale del libro Genealogico ANAPRI del 4 Giugno 2004 “VALUTAZIONE GENETICA PER LE CELLULE SOMATICHE NELLA RAZZA PEZZATA ROSSA ITALIANA” Daniele Vicario, Paolo Carnier	
Key organisation: name, address, phone, fax, e-mail, web site	ANAPRI (ASSOCIAZIONE NAZIONALE ALLEVATORI BOVINI DI RAZZA PEZZATA ROSSA ITALIANA) via I.Nievo,19 I-33100 UDINE-ITALY. Tel. ++39 0432 224111 Fax. ++39 0432 224137, anapri@anapri.it,

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).

Parameters for national genetic evaluations for udder health traits as provided to Interbull

Country (or countries):	ITALY	
Main trait group:	Health	
Breed(s):	SIMMENTAL	

Trait	h2a	Genetic
Variancea	official proof
standardisation formulab	
Milk Somatic Cell:	14.4	0.44831	((Eval-0,0112080229)/0.4987086025)*-12+100	
Clinical Mastitis:
				
a	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.
b	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.
