INRA and animal genetics

Methods for the use and the management of animal genetic resources are one of our main fields of investigation.

Genetic evaluation, which is one of our historical activities, remains a priority regardless of the evolution of the legislative context. Indeed, methods for the genetic management of populations are directly associated with the concept of sustainable development and farming for three reasons:

(1) The acceptance and sustainability of selection are improved by contributing to the definition of selection objectives that include all the different levels of the system from the breeder, to the producer, the processor and the consumer. This requires research developments in modelling but also lasting relationships with those that represent society.

(2) The sustainability of the animal production sectors depends on their profit gain. One of the key factors to selection efficacy is the quality of genetic evaluation, i.e. the quality of the estimation of the genetic value of animals. This activity is continously evolving with new methods, with the traits analyzed and the type of information used. Integrating genomic data, structural as well as functional, is both a stake and a challenge for the Animal Genetics division.

(3) Finally, the management of resources also implies the preservation of genetic diversity on the long-term and the transmission of this heritage to future generations. In the selected populations, methods for genetic improvement must be developed that limit loss of genetic variability. The scientist must also rely on todays context of market segmentation in order to valorise or preserve populations that are little adapted to today's predominant conditions. This requires characterising these populations, searching for economic niches and, in the most difficult cases, accompanying conservation actions that are underway or even organising ex situ conservation.
