Résumé

Dans les schémas de sélection actuels, l'appréciation du potentiel génétique d'une vache laitière ne peut se réaliser que tardivement avec l'instauration d'une production. Il est également bien établi que la régulation endocrinienne de la lactation est un phénomène complexe dans lequel l'hormone de croissance (GH) et son médiateur hépatique l'Insulin-Like Growth Factor I (IGF-I) jouent un rôle central. Dans ce texte, les différentes applications possibles de ces hormones en tant que critère de sélection en production laitière sont discutées.

Summary

In the present scheme of selection, evaluation of the genetic merit of dairy cows is only realized after first lactation. It is also well known that endocrine control of milk production is a complex phenomenon in which growth hormone (GH) and insulin-like growth factor I (IGF-I) play a key role. In this context, the possible application of these hormones as predictive criteria of selection in dairy breeds is discussed herein.
