Précision de l'évaluation génomique chez la poule pondeuse

Abstract : Selection is very important for the egg production domain, which is a growing market worldwide. This market has a very segmented nature, with every country having special specifications, depending on consumers expectations. This means that breeding companies have to produce birds which are adapted, or adaptable, to various breeding conditions, while still being able to produce eggs suitable for consumers expectations. Egg production market is also a very competitive, detained worldwide by only 3 enterprise groups. This means that the selection of the different lines, which are dedicated to fulfill differents production criteria, is a critical step. The genetic progress of selected populations is distributed worldwide, and optimize it is a way to stand out from the competitors.For the last few years, genomic selection is put in place in different sectors. Among other things, this methodology allowed to improve genetic progress in cattle industry, which was a precursor in the utilisation of it. This evaluation methode seems highly promising for the avian sector. To precisely estimate the effect of using it, it is necessary to know the accuracy of genomic evaluation. The main objective of this work is to estimate the precision of genomic evaluation on layers egg quality traits under different scenarios, in comparison with what is observed when using genetic evaluation.
