Fattening beef for froggies. Postweaning evaluations in French beef breeds

This paper presents French genetic evaluations using commercial carcass traits of young bulls and on- field post-weaning growth and morphologic traits recorded on heifers and young cows. Pre-weaning traits are taken into account to avoid selection bias. Heritabilities of post-weaning and carcass traits are moderate. Genetic correlations depend on breeds. Index standardisation, construction of total merit indices and rules of publication are presented.
