Livestock animals are selected to meet certain objectives. The pivotal first step of any selection programme, as well as for its further development or reorientation, is therefore to precisely define the selection objectives to be pursued. They are expressed as a set of traits to be improved, together with their respective weightings.
Objectives most often include a set of production and product quality traits, along with morphological and functional traits. In order to be effective, these selection criteria must be fairly inheritable and easily measurable on individual specimens (or their relatives). Selection criteria have become more and more complex over time in order to incorporate more and more diverse demands.
The objectives of French dairy breed selection programmes are currently geared to take into balanced consideration (based on weightings specific to each breed) various criteria surrounding:
For meat breeds, the selection criteria are notably focused on:
Since the early 2000s, the progress of genomic analysis has opened up new perspectives. For instance, it has already enabled incorporation of specific criteria regarding the elimination of genes causing susceptibility to certain diseases (such as scapie for sheep production).
Criteria like advanced compositional analysis of milk (casein, triglycerides, etc.) and meat quality (tenderness, juiciness, flavour, etc.) will soon be included in selection programmes (Phenofinlait and Qualvigène research programmes).
The purpose of all French selection programmes for cattle, sheep and goat breeds is to enable each breed to best meet the needs of the various sector links, from breeders to consumers. The goal is to optimize breed potential and shape evolution to concord with production system and market developments.
This is why the selection objectives for each breed are only defined and revised (priority traits defined and weighted in relation to one another) once consensus has been reached between the representatives of the various sector supply chain links, from breeder to distributor. To that end, there is a Selection Organization for each breed.
Each Selection Organization, a true "parliament" for the breed of interest, is made up of three colleges:
With technical support provided by the INRA [French national institute for agronomics research] and the Institut de l’Elevage, these organizations, which have received Ministry for Agriculture approval, are in charge of defining breed orientations (selection objectives) but also:
