Résumé
The purpose of this study was to examine the opportunities group breeding schemes offer to sheep breeders in practice. Two breeding schemes were considered in this study to examine the genetic progress made over a 20 year period through finding the most appropriate genetic models, which best described weaning weight of lamb, and estimating the genetic parameters. A focal point in this study is the potential role of group breeding schemes in helping to achieve rapid genetic progress in sheep production traits. In a subsequent section, the application of the concept of group breeding schemes such as sire referencing schemes in the genetic improvement of sheep breeds in Iran are considered and alternative strategies using these concepts are presented. Finally, proposals for appropriate genetic improvement schemes for the sheep industry in Iran are discussed, taking into account the current genetic resources and husbandry systems, as well as the culture, attitudes and aspiration of Iranian sheep farmer
