Abstract Text:

This paper presents the preliminary results obtained during the implementation of a genomic evaluation for egg weight in laying hens. One originality of the project is to have used a population of crossbred hens to estimate GEBV of purebred sires. Moreover, hens were divided in 2 groups fed with 2 diets of Low Energy and High Energy. The genomic evaluation from performances of crossbred daughters is more accurate than traditional genetic evaluation in purebred. The interaction genotype x diet seems to be low.

Keywords:
