Guideline to Form BEEF

You are kindly asked to fill in a Form BEEF for all official traits (weaning weight, carcass traits, conformation etc) as they are recorded in your country, and submit the form to the Interbull Centre ( ). Please follow these guidelines as closely as possible when filling out the form in order to accomplish this and in order for form to be as homogeneous across country as possible.

General guidelines:


Country (or countries)

Give the complete name. Write all country names if joint evaluation.

Trait name

Give complete name of the trait


Give the complete name of the breed(s). If a breed is evaluated together with a different breed, write the breed of evaluation in parenthesis.

Trait definition

Indicate how the trait is defined (e.g. weaning weight as weight at 200 days, weight at 210 days etc).

Method and frequency of measurement

Indicate source of data (e.g. scale, chest circumference etc) and how often data is collected

Who does the performance recording?

Breed associations, breeders, national association, as specified by ICAR general rules of performance recording

Method of collecting data

Explain briefly how records are collected

Which animals get recorded?

Please indicate if the recording involves pure breeds only or if it includes pure and crossbreeds.

Is birthday recorded?

Indicate yes or not.

Is day of recording available?

Indicate yes or not.

Is the data adjusted and/or selected? If yes please describe the methodology applied

Indicate yes or not. If yes, please provide the name of each adjusting factor together with a detailed description of the methodology used to adjust the data. If data is selected please provide a detailed description of the methodology used. Give reference(s) if available.

Time period for inclusion of data

Give a date, e.g. since 1985 etc.

Criteria (data edits) for inclusion of records

e.g. acceptable limits for phenotypic expression, missing pedigree, status of herd/animal, etc.

Is embryo transfer applied? How are ET animals identified? Is recipient mother ID recorded?

Indicate if the technique is, rarely or widely, utilized. Provide a sample of all possible different ID typologies for ET animals in Appendix II Beef, as they are currently identify in your country. Please indicate, also, if the recipient mother ID is recorded.

How do you treat incomplete data?

e.g. if herd is missing would the whole record get deleted or it would be kept assigning it to a common herd id? Please specify all possible scenarios that apply.


Model used for genetic evaluation

Use abbreviations listed in the attached list of abbreviation to define the type of model used. (e.g. ST-AM-FR-DAM-MPE)

Environmental effects

State nature of these effects (e.g. continuous, discontinuous), number of levels, and in parenthesis how they are treated (e.g. fixed=F, random=R).

Use of genetic groups and relationships

Is the relationship matrix modified in any way? What is the grouping based on? Birth year? Country of origin? Etc?

Genetic parameters in the model

Give ALL genetic parameters assumed in genetic model (h2, σ2p, r , c2, etc.) in Appendix I BEEF.

Adjustment for heterogeneous variance in evaluation model

Indicate whether heterogeneous variance is adjusted for in the model. If yes, please provide the methodology applied together with reference(s), if available.

System validation

Explain the validation process: check on data quality /model, trend estimations ...

Definition of genetic reference base Next base change

How is the genetic (reference) base defined: cow or bull; Fixed or rolling; birth year, calving year or proof year; etc.

Assessment of index quality (computation of reliability, connection)

Briefly state how reliabilities are calculated, what the criteria are to define connected herds. Include references if available.


Expression of genetic evaluations

EBV, ETA, etc. If standardized, please provide standardization formula and factors

Criteria for official publication of evaluations

Minimum reliability or number of daughters / herd, etc.

Number of evaluations / publications per year

1, 2, 3 …? Which month(s)?

Anticipated changes in the near future

State the nature and the date of the anticipated / planned change.

Key reference on methodology applied

Please name the key references, which are used as the basis of the current genetic evaluations.

Key organization : contact person, address, phone, fax, e-mail, web site

Be explicit.
