Important Notes 1

  1. Each Organisation providing data for a specific breed-trait(s) evaluation will receive:
  • evaluations’ results for all animals included in the related breed-traits group evaluation, for the trait(s) the Organisation provided the data, expressed on its own base and scale and dedicated exclusively for the purpose of international genetic evaluation;

Important Notes 2

  • evaluations’ results for all animals included in the related breed-traits group evaluation, for the trait(s) the Organisation provided the data, expressed on base and scale of all Organisations participating in the same breed-trait(s) evaluation. These results may only be used for internal validation purposes.

The use of these two kinds of results for any other purposes must be regulated by specific contracts agreed with all other Organisations involved in the specific evaluation.

Important Notes 3

  1. In terms of publishing evaluations’ results, each Organisation **is allowed to publish only results expressed on its own base and scale contained in the files {trt}MD_pub{BRD}_runid.csv**, related to animals identified as publishable according to Interbeef publication rules.

Important Notes 4

  1. Individual Organisations are responsible for publishing results of the international evaluations according to their own requirements; publication should distinguish between the Organisation’s domestic predicted genetic merits and the international predicted genetic merits.
