Summary

Examinded are some of the most important dairy sheep breeds, among the great diversity of the Mediterranean sheep population, by focusing on their phenotypic characteristics, their productive and reproductive potential as well as on the management practices and systems of testing. Information is also given on their genetic parameters, with emphasis on heritability coefficients, and the range of respective selection and breeding schemes, applied under their particular husbandry conditions.

Resume

Parmi la grande diversite qu'offre la population ovine de la region mediterraneenne, on a examine le cas des races les plus importantes de brebis laitieres en s'attachant particulierement a leurs caracteristiques phenotypiques, a leur aptitude a la reproduction et a leur potentiel de production. On s'est attache aussi aux pratiques et aux systemes d'elevage. Les parametres genetiques ont reçu 1'attention necessaire, laquelle a porte en particulier sur les coefficients d'heritabilite et leur selection, ainsi que sur les plans d'elevage.
