SUBSIDIARY LEGISLATION 437.29

PERFORMANCE MONITORING METHODS AND

METHODS FOR ASSESSING CATTLE’S GENETIC

VALUE FOR PURE-BRED BREEDING ANIMALS

OF THE BOVINE SPECIES REGULATIONS *

31st October, 2003

LEGAL NOTICE 323 of 2003.

(1) The title of these regulations is the Performance

Monitoring Methods and Methods for Assessing Cattle’s Genetic

Value for Pure Bred Breeding Animals of the Bovine Species

Regulations.

(2) The scope of these regulations is to implement the

provisions found under European Union Commission Decision 86/

130/EEC laying down performance monitoring methods and

methods for assessing cattle’s genetic value for pure bred breeding

animals of the bovine species. This Decision finds its legal basis

under European Union Council Directive 77/504/EEC, article 6(1),

first indent.

The Veterinary Services of the territory of Malta are to approve the bodies

responsible for setting the rules for performance recording and assessing the genetic

value and for publication of the evaluation results of pure-bred breeding animals of

the bovine species. The names of the approved bodies must be notified to the

European Commission and the Member States.

In particular, these bodies shall give an account of the recording methods, the

model of performance description, the statistical method of analysis and the genetic

parameters used for each evaluated trait.

Performance Recording

All data must be recorded under the responsibility of the approved body.

1. Beef production traits

(a) Individual performance and, or progeny testing at a station

(i)

The test method and the number of animals tested are to be

indicated.

(ii) The following are to be indicated in the test protocol

- conditions for acceptance into the station,

- if applicable, the on-farm-performance of the test animals

prior to entry into the station,

- identity of the owner of the test animals for individual

performance testing,

- maximum age for the test animals entering the station and the

age of range of contemporary animals on the station,

- length of adaptation and test periods at the station,

- type of diet and system of feeding.

(iii) Traits recorded: the minimum traits to be recorded include live

weight gain and muscular development (beef conformation) and,

if available, other traits such as feed conversion and carcass trait.

Specialised units can operate as stations under the responsibility

of the approved body.

(b) Testing in the field (on-farm).

The test method and the method to validate test results must be provided

by the approved body. The minimum traits to be recorded include live

weight and age and, if available, other traits such as beef conformation.

(c) Testing through survey data from farms and points of sale and slaughter.

If available and appropriate the live and slaughter weights, sales prices,

carcass grade according to the Community carcass classification

scheme, meat quality and other beef traits must be recorded.

2. Milk recording

Recording milk production data must comply with the principles agreed by

competent international bodies (e. g. International Committee for Animal Recording

The performance monitoring methods and methods for

assessing cattle’s genetic value for purebred breeding animals of

the bovine species shall be those as laid down in the Schedule.

*These Regulations have been repealed by Legal Notice 11 of 2024.

BRED BREEDING ANIMALS OF THE BOVINE SPECIES

Reproduction (secondary traits)

When fertility, calving aptitude and longevity are being evaluated, they must be

BRED BREEDING ANIMALS OF THE BOVINE SPECIES

assessed on the basis of data on fertilisation (e. g. non-return-rate), calving score and

on functional age (e. g. Stay-ability, culling age, length of productive life),

respectively.

Morphological (type) assessment

When morphological rating is carried out, it must be done using an approved

recording system.

III.

Genetic evaluation

1. Principles

The genetic evaluation of breeding animals must be carried out under the

responsibility of the approved body and must include the following performance

traits according to the selection objectives

-

milk production traits for animals of dairy breeds,

-

beef production traits for animals of beef breeds,

-

milk and beef production traits for dual-purpose breeds.

Furthermore, it is recommended that the genetic evaluation should also include the

traits of reproductive performance and of morphology for breeds in which recording

of these traits is being practised.

The breeding value of an animal is calculated on the basis of the results of the

performance of the individual and, or of its relatives.

The statistical methods applied in genetic evaluation must comply with the

principles agreed by competent international bodies (e.g. ICAR) and should

guarantee a genetic evaluation unbiased from the influences of the main

environmental factors and data structure.

The reliability of the genetic evaluation must be measured as the coefficient of

determination in accordance with principles agreed by competent international

bodies (e. g. ICAR). When publishing the evaluation results, the reliability as well as

the date of evaluation must be given.

Genetic peculiarities and genetic defects of an animal defined by the bodies

officially appointed for the determination of these characters, in agreement with the

breeders organisations or associations, recognised in conformity with Commission

Decision 84/247/EEC, have to be published.

2. Genetic evaluation of bulls for artificial insemination

The bulls must be subjected to a genetic evaluation on compulsory traits and

breeding values on them must be published. Other available breeding values also

must be published.

These provisions do not apply to breeds threatened with extinction.

(a) Genetic evaluation of artificial insemination bulls for milk production

traits

In the genetic evaluation of dairy traits, the milk yield and content

(butterfat and protein percentage) as well as other available and relevant

data for the genetic aptitude for dairy traits must be included.

The minimum reliability of the genetic evaluation of AI bulls of the

dairy breeds must be at least 0,5 for the main production traits

according to ICAR principles taking into account all information from

relatives.

BRED BREEDING ANIMALS OF THE BOVINE SPECIES

(b) Genetic evaluation of artificial insemination bulls fof beef production

traits

The genetic evaluation of these bulls is carried out on the basis of one of

the following performance testing methods

(i) individual performance testing on station;

(ii) progeny and, or sib test on station or in specialised units;

(iii) progeny and, or sib test on farm; in such a way that the offspring’s

are distributed among the recorded herds to allow a valid

comparison of bulls to be made;

(iv) progeny and, or sib test by means of collecting data on farms, in

auction sales or in slaughter houses in such a way that a valid

comparison of bulls can be made.

If carcass weight and, where appropriate, traits of meat quality, growth

performance and calving aptitude are being recorded, these traits as well as any other

relevant trait must be included in the genetic evaluation of the bull.
