'''Environmental effects, pre-adjustments''' What are the records adjusted for (age, heterogeneous variance, days open, etc)? Are pre-adjustments additive or multiplicative, i.e. affecting only the mean or both mean and variance? Write the relevant pre-adjustment equations and provide a copy of the key reference. How often are pre-adjustment factors updated (last update)? Give the base in months for age adjustments, if applicable. Sex code Character 1
Line 39: Line 37:
'''Method (model) of genetic evaluation '''Use abbreviations for most common effects (list of abbreviations available on our website under Service> Service Documentation >Abbreviations to use in Interbull forms) e.g. MT-ML-RR-AM, Survival kit. If weighted analysis (e.g. records in progress) please give weights.

ID number of bull Character 12

Guideline to Form ID

You are kindly asked to fill in a Form ID to describe the identification system in your country and submit the form to the Interbull Centre ( interbull@slu.se ). Please follow these guidelines as closely as possible when filling out the form in order to accomplish this and in order for forms to be as homogeneous across country as possible.

General Guidelines

  • Write in English.
  • Do not modify the form, i.e. keep all appendices even if they are empty, but feel free to add for
    instance tables with genetic (co-)variances.

  • Be detailed, but concise.
  • Quantify answers wherever possible.
  • use one form per breed or one form for all breeds.
  • If the ID system has been modified at any time, please fill in tables with Description of changes in ID system and repeat each question for each time the system has been modified.
  • Give as detailed information as possible, but remember that some information is better than no information!

Specific Guidelines:

Country (or countries) Give the complete name. Write all country names if joint evaluation.

Breed(s)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.

Rules to define breed codes How do you define the difference between, for instance, HOL/RED and SIM/MON. Briefly state the criteria for the 3 character breed code (position 1-3 in the international ID*).

Distinct ID number ranges If distinst number ranges is used for e.g. different breeds, sex, birth years etc please state the number ranges

Re-use of ID If yes please state the rules for re-use.

Semen straw information Briefly describe the relation between information on semen straws and the (International) ID. Please indicate where a cross-reference list can be found in case of inconsistencies.

National vs International: Is the 19 character international ID also used as national ID? If not, please describe what the rules for transforming national bull ID's to the International bull ID's
