laying down performance monitoring methods and methods for
assessing cattle's genetic value for pure bred breeding animals of
thebovinespecies
(86/130/EEC)
THE COMMISSION OF THE EUROPEAN COMMUNITIES,
Having regard to the Treaty establishing the European Economic
Community,
Having regard to Council Directive 77/504/EEC of 25 July 1977 on
pure bred breeding animals of the bovine species(1), as last amended
by the Act of Accession of Greece, and in particular the first indentof Article 6 (1) thereof,
Whereas under the first indent of Article 6 (1) of Directive 77/504/EEC
it is for the Commission to determine, in accordance with the proce-dure laid down in Article 8 of the abovementioned Directive, the
performance monitoring methods and methods for assessing cattle's
genetic value;
Whereas the methods for performance monitoring and assessing cattle's
genetic value already being applied in the Member States are broadlysimilar;
Whereas it is therefore necessary to align the modalities of these
methods more closely so that the results are comparable;
Whereas the measures provided for in this Decision are in accordance
with the opinion of the Standing Committee on Zootechnics,
HAS ADOPTED THIS DECISION:
Article 1
The performance monitoring methods and methods for assessing
cattle's genetic value for pure bred breeding animals of the bovine
species shall be those as laid down in the Annex to this Decision.
Article 2
This Decision is addressed to the Member States.1986D0130 — EN — 11.03.1986 — 000.001 — 2

ANNEX
The genetic merit of a bovine animal may be calculated using one or a combi-
nation of the following methods, all the data accruing from the test results shall
be accessible:
1.Performance Testing
(i)Performance Testing on a station
(a) The name of the body or of the authority responsible for the station
and the name of the competent authority for the calculation and
publication of the results shall be given.
(b) The design of the test and the number of animals involved in it shall
be stated.
(c) The following items shall be clearly stated:
— conditions for acceptance into the station,
— on farm performance of bulls prior to entry into the station if
applicable,
— ownership and maximum age of young bulls entering the station
at the time of the test and the range of ages of contemporary
bulls in the station,
— length of the adaptation period and test period in the station,— type of diet and system of feeding.
(d) For traits being recorded; the minimum traits to be recorded must be
liveweight. For beef breeds in addition feed intake and muscle
assessment.
(e) The method used for estimating genetic merit must be unbiased. The
genetic merit of tested bulls must be stated as a breeding value or
contemporary comparison for eachtrait.
(ii)Performance testing on a farm
A performance test may be carried out outside a station providing that at
the end of the test a breeding value can be calculated following estab-
lished zootechnical principles.
2.Milkrecordingandassessmentofthebreedingvalueoffemalesformilk
traits
Milk yield records used for the assessment of the breeding value of females
must be obtained under an official system of milk recording complying with
standards laid down by the International Committee for Recording the
Productivity of Milk Animals.
The name of the body or of the authority responsible for the calculation and
publication of the results shall be given.
Milk records used in the determination of the breeding value of females
must:
— have a standard length of lactation for calculation purposes of 305 days,
— be adjusted for any important environmental influences by appropriate
means.
The method used for the estimation of genetic merit must be unbiased and
the result expressed as a predicted difference or breeding value with asso-
ciated accuracy values for all traits concerned.
A detailed description of the method used must be given or referenced. Traits
evaluated must be defined, the base reference and standard deviation of the
traits must be stated and the date of calculation of the figures must be given.
3.ProgenyTesting
(a) The name of the body or of the authority responsible for the station and
the name of the competent authority for the calculation and publication
of the results shall be given.
(b) The genetic merit of the sire shall be calculated by assessing the qualities
of a suitable number of its offspring in relation to:
(i) Dairy characteristics:
— a detailed description of the progeny test method must be given
or referenced,
— the daughters should not be selectively procured or selectively
treated,1986D0130 — EN — 11.03.1986 — 000.001 — 3
▼B
— first lactations must be used and later lactations may be used;
lactation records used must have a maximum length of 305 days
►C1and be obtained under an official system of milk
recording ◄complying withstandards laid down by th e Interna-
tional Committee for Recording the Productivity of Milk
Animals,
— influences other than the genetic merit of the sire must be elimi-
nated by appropriate procedures in the determination of its
breeding value or predicted differences,
— the quantity and composition of the milk produced and other
relevant data shall be included when calculating breeding values
►C1or predicted differences ◄,
— if data are available concerning fertility and the viability of the
progeny they shall be published,
— the method used for estimating breeding values or predicted
differences must be unbiased,
— results must be published in the form of predicted difference or
breeding values withassociated accuracy values for th e main
production traits recorded. Traits evaluated must be defined, the
base reference and the standard deviation of the traits must be
stated and the date of calculation of the figures must be given.
(ii) Beef characteristics:
— a detailed description of the progeny test method must be given
or referenced,
— the progeny should not be selectively procured or selectively
treated,
— four types of progeny tests are recognized:
A. central testing in specialized progeny testing units;
B. planned progeny testing in cooperating commercial beef
production units;
C. analysis of data from on-farm recording schemes for pedigree
and/or commercial herds. The progeny should be distributed
amongst herds in such a way that a valid comparison between
bulls is possible;
D. survey type data collected on identified progeny at sale or
slaughter premises.
In types A and B animals must be selected in a random way at a
young age, and brought together into contemporary groups
balanced withrespect to bulls involved. In types C and D all
qualifying records must be used in assessing the breeding value
of the bulls
— bulls for progeny testing must be used at random in herds from
which it is planned to procure progeny for testing,
— influences other than the genetic merit of the sire must be elimi-
nated by appropriate procedures in the determination of its
breeding value,
— the carcase characteristics (where these are part of a selection
programme) and its quality and other relevant data shall be
included when calculating breeding values,
— if data are available concerning fertility and the viability of the
progeny they shall be published,
— the method used for estimating breeding values must be
unbiased,
— results must as far as possible be published in the form of
predicted difference or breeding values withassociated accuracy
values for the main traits recorded. Traits evaluated must be
defined, the base reference and the standard deviation of the
traits must be stated and the date of calculation of the figures
must be given.1986D0130 — EN — 11.03.1986 — 000.001 — 4
