The objective of our study is to contribute to improving the knowledge of sheep production systems in\nthe steppe areas. Our methodology consists to make a survey with a representative number of sheep\nbreeders, and using the principal component analysis (PCA) -which has high capacity of\ndiscrimination- for the typology in order to make a description of each type. The choice of the study\narea was dictated by the volume of sheep production in the region, the latter being the first producer\nnationally. The surveyed sheep breeders were identified in three essential types: transhumant,\nsemi-sedentary and sedentary.
