1. INTRODUCTION

Countries willing to join InterBeef must be members of Interbull and support the ICAR guidelines for data collection (http://www.icar.org/). This document is a description of the necessary actions and relevant files required by a new country willing to join InterBeef.

2. THE ANIMAL INTERNATIONAL IDENTIFICATION

2.1 Format

A unique international identification for each animal is used in the international genetic evaluation system and will be referred to as the Animal International IDentification (AIID). The AIID is constructed using the Interbull rules (referred as Interbull format in the document) and its structure is:

Breed + Country + Sex + Identification number


Ex: CHAFRAM006327826864 refers to


Ex: BAQIRLF125693456875 refers to


2.2 Constructing the international identification number

A country should first construct the international identifications for the animals born on its soil. The general rule for this construction would be that a given identification number is unique within a country and a breed.


When an animal (live animal or issued from AI straw or embryo) is sold abroad, the importing country should avoid re-registration; in case of re-registration the original ID and the national ID should be kept.


The animal ‘IE231112150014’ is, for example, a pure breed Irish limousine female named ‘SHRIFFTOWN RIPPER’. Ireland has constructed its AIID as followed: LIMIRLF231112150014.


The animal ‘FR0384106449’ is a pure breed French Charolais bull named ‘VLADIMIR’. That animal is also used in Ireland under the name ‘VLADIMER’ and the number ‘0384106449’ and has also been re-codified ‘108376849’ and ‘VLR’. France constructs its AIID as followed: CHAFRAM000384106449.


In the international identification number, hyphens, slashes, commas, dots, blank spaces or any other symbols are allowed.


The animal ‘UK9373 70-2/-7’, for example, is a UK Salers female animal and its international identification number would be ‘SALGBRF9373 70-2/-7’

2.3 The New Web Interface at Interbull

Interbull has developed a new database, IDEA (Interbull Data Exchange Area) that allows register users to all the pedigree handling functionalities. IDEA is available at https://idea.interbull.org/

IDEA is exclusive for database users. To become a database user you need to belong to a national evaluation centre participating to the Interbeef evaluation. If you want to join the Interbeef evaluation and therefore have access to IDEA, your national genetic centre needs to be associated to a username and a contact email address. To get your national genetic centre listed among the ones participating to the Interbeef evaluation, you have to:

Send an email to interbeef@hgen.slu.se providing information on your national genetic centre: Full name and address of the organization and full name and email address of the designated contact person. Clearly state the breed(s) and trait(s) you wish to participate with. If your organization provides data as a joint evaluation including other countries, you clearly have to state for which other countries and breed(s) your organization provides pedigree and performance information.

Upon reception of your request, Interbull will send you by email a link to an IDEA-test environment together with a username and password so that you will be able to get acquainted with the IDEA functionalities and the user manual which is located under “Help”.

The national pedigree file must be first checked with the CheckPedigree.py script provided by Interbull Centre. The checking programs are available under “Software”. The zip files produced by the Python scripts represent the only valid infiles for the database; no other files will be accepted by the system.
When your pedigree enters the database it undergoes a series of checks called “verification process” aiming at identifying the correct authoritative organization of each and every animals listed in your pedigree. In general the system has been built in such a way that it accepts information only if these comes from the authoritative organization. Therefore, whenever you submit pedigree data, the system first checks that the combination “country-breed” in the animal ID matches with the combination your organization “owns”. If so the records are considered correct and stored in the database, if this is not the case then the records will be listed in the appropriate authoritative organization account waiting for verification, i.e. waiting for the authoritative organization to provide the correct pedigree information. In case the authoritative organization is a country or organization that does not yet participate to the Interbeef evaluation, then the animals will appear as verified by Interbull until eventually that country/organization would join the service.

Example:
Ireland submits the following pedigree records to the database:

601 CHAIRLM458962315289 CHAIRLM789456123652 CHAIRLF369852147852 1985 OMAR IRL
601 CHAFRAM865412398745 CHAFRAM231658479851 CHAFRAF845693274125 1988 OSCAR IRL

In the first case the animal is an Irish Charolais sent by Ireland. Ireland is therefore the authoritative organization for that animal so the record gets stored in the database. In the second case the animal appears to be a French Charolais sent by Ireland. Ireland is no longer the authoritative organization for this bull therefore the system will send the record to the French account and will wait for France to provide its correct pedigree information.

3. THE REQUIRED FILES

There are 5 groups of files to be created by a country willing to join the international beef genetic evaluation:

A country willing to join InterBeef needs to include at least one breed and one trait in the process of the international genetic evaluation. The objective of the present document is to help a new member country in the construction of these files.

NB: Since the verification of the International ID is done via database, national cross-reference files are no longer needed. For more information about IID verification, please refer to the IDEA user manual.

3.1 General

3.1.1 The Different InterBeef steps

The construction of these files follows several steps:

3.2 Fileformats

3.2.1 The national pedigree file (601 file)

3.2.1.0 General

The 601 file is a national pedigree file and must contain pedigree information of all animals included in the performance file in an animal-sire-dam format. Sires, dams and ancestors must also have an entry in this file as an animal; unknown ancestors should be coded ‘UUUUUUUUUUUUUUUUUUU’.

To ensure sufficient pedigree information it is recommended that pedigree information of animals born within a period equivalent to a minimum of three generation intervals should be included. The 601 file is a file issued per country or organization providing pedigree information according to the format shown in Table 1. The 601 files can contain one breed or multiple breeds.

3.2.2 The performance file (602)

3.2.2.0 General

All animals with a performance must have a line as animal in the 601 pedigree file. The performance file must be constructed in agreement with the 601 file and be consistent with the international identification of the animal.
It is expected that countries participating with data support the ICAR guidelines for beef recording.
As indicated in the ICAR recommendations, any group of animals kept for the same purpose and at the same location shall be regarded as a whole herd. For a performance record to be considered an official record, the whole herd as defined above must be recorded. Each herd is identified with 15 digits identification, coded as characters:

All performance traits are associated with their environmental effects and complementary information (one observation line per measurement) as described in Table 2.

3.2.2.0.1 Crossbreed animals

At the combined Interbeef Technical- and Working group meeting in Padova, Italy, the 11:th - 12:th of October it was decided to include crossbreed animals in the animal weaning weight evaluation for all breeds of evaluation (HER,AAN,BSM, LIM and CHA). This means that performance records for crossbreed animals in the performance file will be included in the international genetic evaluation. A calf with sire breed = breed of evaluaiton (i.g LIM,CHA, BSM,HER or AAN) and dam breed = any other breed is considered to be cross breed and should have breed code XXX (i,g XXXIRLM123456122333). The pedigree records for the crossbreeds should be uploaded in IDEA as usual.

3.2.2.1 Special information for calving traits

Calving traits present a direct and a maternal component. For some traits, such as stillbirth and birth weight preparation of a file602 can be difficult because of the absence of an international ID for a dead calf. Given that Interbeef is an international data sharing platform, it is absolutely necessary that records are exchanged in a standardized way and that data quality must be ensured at the best of our capacity. Based on these two principles, there is a strong intention to keep phenotypic records under an universal formats capable of handling all possible traits (files 602 and 603). Likewise, only valid international animal idetification is admitted into the system (file 601).

Phenotypic records for calving traits will therefore be reported as maternal traits (the International ID of ANIMAL in the file602 will refer to the dam ID) with the necessary information to fit a model for the direct trait added in the "environmental effects" fields of file 602. This includes additional information about the calf, such as sire of the calf, sex of the calf, calf birth date and calf ID (when available). Consider, for instance a record for calving ease (cae). In file 602, a typical record could be reported as shown in Table 2 and in session "Examples performance and parameter files" - calving traits

When calf additional information is reported in File602 (Table 2), the equivalent parameter File603 should also refer to the same variables. Although calf additional information is reported in the "environmental effects" field, it is not necessarily intended to be fit as an effect into the statistical model for the maternal trait. Since records on file 602 refer do the CALF DAM, in the parameter file the type of effects refer to the model for the maternal trait only. Therefore, variables that are reported in File602 to be used in the direct trait model should be labeled as "C" in the effect type field, so it is clear they are not fixed or random effects, neither covariates in the maternal trait model.

In the example in session "Examples performance and parameter file" for calving traits, calf sex, parity, season and age at calving are included as a fixed effects (effect type "F" in File603), while calf sire, calf birthdate and calf ID are labelled as effect type "C", which means they will not be fitted in the maternal trait model, but used for modelling the direct effect. For instance, calf ID, calf sire and calf birthdate would be needed to create a pedigree structure for the direct trait analyses.

3.2.4 ET file (604)

3.2.4.0 General

The ET file (604) contains a list of ET IDs which will be included in the pedigree used for the international evaluation. Country willing to get international breeding values for ET animals based on parent average will have to provide the file at each evaluation. This file is not a mandatory file. Please note: For calving traits, the embryo transfer field in the 602 file is related the the calf and not the the dam itself.

3.2.5.0 General

The OFCL file (605) contains a list of IDs of animals with official proof in the participating country. According to a new proposal for the publication policy, if the national proof of an animal is considered as official, the international predicted breeding value of the animal on the scale of that country would be publishable.

All transferred files should be written in ASCII format and use character encoding: UTF-8

Specifically for the pedigree files, organizations will find access in IDEA to two Python scripts, CheckPedigree.py and CheckLinks.py. Aim of these scripts is to assure that pedigree and linking information are correct prior entering the database environment. To run the script type at the prompt:

Python2.6 CheckPedigree.py –m {organization code(1)} –f {pedigree file name}

For more information about the CheckPedigree.py and the CheckLinks.py see Appendix I (a and b).

If the scripts detect no errors in the pedigree or link file then a zip file “IB-ORGCODE-yyyymmddThhmmss.zip.” or “IB202-org_code-yyyymmddThhmmss.zip” would be created. The zip file produced by the Python scripts represent the infile for the Interbull database; no other file would be accepted.


For the time being before the database would be ready to accept performance and parameter file the nomenclature for these types of files would be:

COUNTRY.BREED.FILE.TRAIT_TYPE.DATE(2)

For example, a file from Ireland with performance for Limousine sent on 2010-01-18 would be called: IRL.LIM.F602.AWW_20100118
A parameter file from the same country and breed would be called IRL.LIM.F603.AWW_20100118

(1) For the Org.Code, see Reference section. (2) date yyyymmdd format

README for CheckPedigree.py

Updated: 2012-12-12

Information about the program:

CheckPedigree.py will perform a series of checks on your pedigree data to insure that the data is all right. If no errors are detected then a zip file will be created. The zip file represents your checked pedigree file to upload to the Interbull Centre IDEA database. For technical reason the program rejects files containing more than a million of data.

The checks relate to:

  • Check the international identification numbers (animal, sire and dam)
    • Correct three digit country code as in the ISO 3166 standard (no missing countries allowed)
    • Correct three digit breed code according to the Interbull breed codes
    • Correct construction of the numerical part of the ID (registration numbers, right justified, leading blanks as zeros)
    • Missing sires and dams shall be coded as UUUUUUUUUUUUUUUUUUU (i.e. with 19 U)
  • Check the animal's birth date
    • Has to be reported in the format YYYYMMDD
    • If you know only the year of birth then enter it as YYYY0000
    • If you know year and month of birth then enter them as YYYYMM00
    • Missing birth dates are coded as 00000000 (or blanks or a single 0)
  • Check that a male (or female) animal will eventually appear only as sire (or dam)
  • Check for inconsistent duplicate records (different sire, dam or birthdate)
  • Check that an animal is always younger than its parents and grandparents

Before Running the Program:

  1. Install Python (version 2.5 to 2.7) if necessary

  2. Create a working directory/folder
  3. Download the CheckPedigree.py program from https://idea.interbull.org/software and copy it to your new directory

  4. Copy your pedigree file to the working directory

Running the Program:

  • Ensure there is a working network connection
  • Use the command: python CheckPedigree.py -m <ORGCODE> -f <filename>

  • Use your uppercase ORGCODE as shown on the upper right hand side of the IDEA page.Your organization code is reported within brackets beside the "Logged in as" information.

  • The program checks its internal version with the value stored on the Interbull server. You will have to download the most recent version if there is a mismatch.
  • If you want to inspect a pedigree file containing more than a million record you can do so by adding a "-t" at the end of the command line. By doing so, your pedigree will be only tested for its correctedness but no output will be created. The command line to use will be therefore: python CheckPedigree.py -m <ORGCODE> -f <filename> -t

After Running the Program:

If no errors are detected, the pedigree file will be written into a zip file called IB-ORGCODE-yyyymmddThhmmss.zip. Upload the zip file to Interbull's data exchange site: https://idea.interbull.org/.

In case of errors, no zip file will be created. Please correct your data and re-run the program until the data successfully pass all required checks.

Specific information about your pedigree data, descriptive statistics and a summary of errors are written to the file CheckPedigreeLog.txt.

All errors are listed in detail in the file called CheckPedigreeErrors.txt. The following table describes the brief error messages more fully:

Error message

Description

Inconsistent duplicates

An animal appears twice with different sire, dam or birth date

Warning duplicates

An animal appears twice but with same sire, dam and birth date

Illegal character errors

The numerical part of the international ID is not valid

Breed-country error

The breed-country combination is not recognized
- see file CheckPedigreeAuth.txt (created by the program)

Sex coding error

The sex code is neither M nor F

Parent sex error

A male animal (or a female) appears in the dam (or sire) column

Birth date errors

Malformed entry for birth date

Ancestor check

Animal appears older than its parents or grandparents
- if a parent's birth date is unknown, grandparents are checked

Pedigree loops

Animal appears further back in its pedigree tree as an ancestor of itself

Too many animals detected

For technical reason the number of pedigree lines that can be submitted in each file has been limited to 1 million. If your file exceeds such limit you need to split its content into two (or more) files and test each of them with the CheckPedigree.py program

Note

Please do not modify the program to circumvent any checks. Doing so would be pointless because the same checking routine is used again inside IDEA to double-check the pedigree file uploaded in the zip file.
